I have been dealing with a faulty cluster on a 01 silverado diesel. Recently bought the truck and needed the odometer fixed to title the truck. The service screen and odometer booth where not working. Was at a loss until i saw this video. After a close examination of the board with an ohm meter . I determond the same diode was bad on my cluster as this video. I managed to get a diode that ohm @ .533 that was close enough to the .60 that yours showed. Installed it and all is good. Powers up and functions as it should. Was also impressed with the mileage being lower than i thought it would be. Thank you for the information contained in this video.
Thanks for posting this operation. I just bought a 2000 GMC and have a cluster issue. So I’m absorbing as much info on this, before I jump into it. So knowing other issues ahead of time helps so much when in unknown waters. Just to share another known issue with these things, there’s a black & white (ground?) wire going to the main plug on cluster that fails. It goes to the back of the engine some where. Not sure of its failure origins, but wanted to share the knowledge. I made sure I liked 👍 and subscribed to your channel.
Hello, Love your video. I have a 2002 chevy silverado 3500 with instrument issues. Odometer and gear selector not illuminating, diesel gauge not working, trans Temp doesn't seem to work, and temp doesn't seem to work. Battery light stays on. Volts gauge oil gauge, blinkers, mph and r p m seem to wrork. If I tap on the dash the Rpm needle jumps and the blinker arrows come on . Can I send my instrument cluster to you for repair?
I have the gas gage problem I replaced the gas stepper motor. I tanked the car full and put it in Ignition Position on and set the needle to full but when I shut it off it goes to the bottom right. Could it be the sending unit for a 1999 Buick Regal? And were is that? Thanks!
on my 99 silverado i remember the odometer being dead when i bought the truck, i pulled it apart soldered some broke/cracked connections, put it back in the truck and about had a stroke. Discovered the damn thing had 319,000 on it.
I bought my 2003 Tahoe because i thought had 130 miles but the cluster lights went off, so i found somebody to fix it and he told me he can put any miles he want on it and any body that knows about it can do the same, i felt bad cause the guy that sold me the truck could've paid someone to put 130000 miles to sell it and cause i wouldn't buy any car over 200000 miles, i hope those are the right miles
You ever think about swapping engines with the odemtor have the old engines miles still on there some people swap the engines out and dont put the engine miles on the cluster
@@Nelval573 were I'm located the odometer is supposed to show the miles of the chassis, not the engine. Replacing the engine is not a justification to roll back the odometer.
I had my cluster out earlier today to chase down an electrical issue that seems to be an inoperative BCM, and out of curiosity, pulled my cluster out to see why my Check Engine, ABS, and Brake lights have never worked since I bought the truck. Someone unsoldered and removed them from the board. Sigh. Any idea what LED should go in place of them?
Question, I have the same board and probably could just follow your steps because I have the exact same issue. Problem is time to tinker with stuff like this. Do you offer a service where I can send my cluster in to have it fixed?
Question!!! Where can I get the twist sockets for the replaceable bulbs for the 99-02? Mine has the Wagner PC194 bulbs which are soldered to the bulb sockets. Someone had replaced one of mine because it was removable, but there are no identifying marks on the socket besides a 6 or 9↕️. It is grey. All the ones I've found online are the wrong size or have the locking tabs in the wrong place.
I've always had plenty of good cores to pull working ones from. Those bulbs usually last 300k+ miles. I've never needed to track down the socket part number. Sorry I can't help.
@@jeffescortlx your good. Yeah, I can buy the replacements for those pretty easily, but I'm afraid the bulbs won't come out of those either. One is blown in my cluster so I just figured why not go to LEDs. Multiple attempts buying sockets to no avail. They all twist too far past the contact strips on the board, if I turn back a little it won't be secure. Does no one change these over to LEDs properly? All I can find are the wrong darn sockets.
@@jonathanst89 I'm my experience most of those pre-assembled 194 LEDs only last about 90 days and then start flickering and failing. You can solder them in directly.
@@jeffescortlx I bought the LEDs separately from the sockets because I have a particular brand LED I always use thats never failed me on headlights, tail lights, turn signals. I agree though with that prepackaged junk, those paper clip contacts are just sad lol I don't really want to solder anything, I'm not very good at it and I want to be able to easily go back to halogen or other LEDs. I'm just going to keep looking for the sockets, I know they're out there somewhere!
HI Jeff, thanks for sharing all of your awesome videos and help! I've browsed through several but cant find my issue. Have you seen a cluster in this 99-02 range that displays solid Security light, Low Fuel, and Battery light. But the truck starts and runs perfect (so I dont think it's Passlock), fuel guage shows empty when full, and also have an ABS and Airbag light. Then the security thing drains the battery dead over night. Someone in a forum said they swapped clusters and it fixed it, but my cluster solder looks great with no burns or anything unusual. Thanks so much!
For anyone else searching, this other video solved my security light, battery light, and low fuel light and guage problem. th-cam.com/video/KxGE8bPCGco/w-d-xo.html Now I just need to figure out why I have an ABS and airbag light together.
This would be great to know. Mine does the same thing intermittently but when I put my foot on the brake pedal just enough for the brake lights to come on it all comes back to normal. And when I lose all those gauges and the lights come on I lose OBD2 communication because my gauge monitor loses connection. I’ve tried almost everything I can think of with no luck
@@jeffescortlx I’ve checked and rechecked the grounds. And if I did it right, I’m pretty sure there’s power/signal going to the engine speed and vehicle speed connectors. For those 4 prong connections to the needles for the tach/speed needles, should one of those be ground? With everything disconnected, one lead on A8, should I have continuity through one of the four slots?
@@jeffescortlx so tested more with the multimeter. With the engine running, A2 (engine speed signal) is getting a constant 6.15v, but revving the engine to increase RPM doesn’t change that voltage at all. I’m guessing it should increase voltage as the RPM’s increase?
@@jeffescortlx I don’t think so, I doubt it, though. I had my scanner connected to the OBDII port and it was showing rpm and vehicle speed in the live view.
Any way I can some info when to send you my 2002 Chevy Silverado 2500 hd cluster ? I tried the ground but I keeps acting up . I hope you are able to help me 🙏🙏
Jeff, your videos are very informative. . I am replacing the needles in my 99 sierra cluster. 2 of my air core motors free spin like you e shown in your vids. In one, you used a syringe and oil to form them up. Can you tell me what setup you use to rejuvenate them? Than you, Bill Dalbey
@@jeffescortlx thank you Jeff for your quick reply. I ended up going to a local you pull yard and checked used clusters until I found a motor for my fuel gauge and oil pressure gauge too. Ended up finding a much nicer face too. (Mine has all of the orange "warning" hash Mark's faded off. That's why I bought new needles off of ebay.) What type or grade of oil do you use to fill the air coils and is the syringe just pushing the oil into the housing around the pointer pin? Thank you again for your knowledge sharing and your channel.
Jeff, Sorry about the oil question. I went through your older replies to other folks and got the answer. I put my cluster back in my truck this evening. Calibrated all of my gauges and every thing worked fine. When I started the truck, my tach isnt working. I used a better face and moved my air cores that were functioning properly, 1 at a time, so as to make sure they went to the proper location. I took the truck for a drive. Used my GPS to check speedo. Everything is functioning except the tach. I pulled the cluster and re installed the motor to insure that it was seated properly. No change. Also, I used the fully functioning circuit board from my old cluster so my odometer would be accurate. The tach was fully functional before this. Where do I go from here?
@@jeffescortlx , you were absolutely right. The motor for my tach was 180 degrees out. Thank you so much for your knowledge and willingness to share it.
Hi Jeff, I have repaired the solder joints on my 2000 Silverado cluster and I am trying to find a pinout to bench test the odometer display on the cluster only. Is there any way you could help me figure that out? Thanks so much I’m advance. Great information in your videos.
jeffescortlx thanks for the reply. I brought the cluster to work with me to repair the solder joints and don’t have the truck with me. I was just hoping there were 2 pins I could supply power and ground to in order to test the odometer display by itself. Is that a possibility or is it way more complicated than that? If it is I’ll just wait until I get home with it and can plug it back into the truck. Thanks again.
@@Mkearns97 You'll need +12 constant, +12 ignition and ground for bare minimum to boot it up. Wiring diagrams are floating around with a Google search.
Great Video. I have 2002 Suburban that makes a pulsating clicking noise that goes away when I dim the interior lights. Do you have any information or video on this issue. Thanks!
I have the exact same issue with the massage center and PRNDL but when I press the dash for a moment it comes back, so I am guessing a bad contact or solder joint, add to that I have a faceplate that's totally warped, and cant seem to find someone to fix the the message and PRNDL intermittent AND the faceplate at the same time, very frustrated. issue
Great video very informative. I have a 99 Chevy that the odometer display will only show anything if I push the reset button very hard for about 30 seconds. I was just going to replace it, do you think it could be caused by the same issue. I’d take it in but I use my truck too much to be without it at all. I generally do all my own repairs. I’m no technician I’m horrible diagnosing. However I’m a good mechanic I can swap parts.
So I have a 99 gmc sierra 1500 5.3v8 recently my gages sometimes while driving or sometimes just idling the truck will run stay running but my batter light comes on my volts stay up but my fuel say empty my rpms says 0 and then when it decides to come.back everything works like normal but one morning I started it up let it idle and my battery light came on. My gas my rpms needle started dancing up down up down my milage started to flip from trip to odometer trip to odometer any thoughts
I have an 02 Silverado and recently replaced the gauge bulbs with leds in the twist sockets drove it for a few days then it blew a the transistor by the barcode on the board but I can’t find one or any info on it, wandering what I can replace it with
Can I send you my 99 cluster? If so, how much to repair display and possible other issues that might be wrong with it? And also, what's the turn around time on a repair?
i replaced the needles on my 02 yukon and i noticed that the speedometer needle is a lil off. When the meter is at 20 it feels like i’m going 30. Do you know why this could be ?
Is there a way to keep my Stability Control error from lighting up on my 2002 Escalade message center? The ABS/EBCM Modules are no longer available for it and I don't want to spend anymore money on it having it rebuilt.
I guess you would have to find someone to write you a modified file and reflash the module. But it would probably be cheaper to just have it repaired rather than hire a software engineer?
I still need more information about it I wanted to see how to swap it out the (PRND321) (diode) my meter is reading right at the number on the resistors and makes a sound I really don’t know what’s the problem with my Diode…
Unfortunately I’m back I did the ground cable repair on the cluster harness a while back. It worked perfectly up till 2 days ago now my gauges have all stopped working but my back lights miles work battery light flashing everything works fine truck is getting 14v at obd2 port with my scanner tool
@@BRED23 I'm not sure what all the fuse box labels are. Some of them are labeled to be for the instrument cluster and some are not. I would recommend giving a look over all of the fuses, both under the hood and in the dashboard.
0 blown fuses cluster will randomly start working and the chime will sound when the cluster dies temp gauge seems to be completely dead now when the gauges work the PRND321 will not shine on but once the cluster “dies” gauges go off the PRND will turn on like normal
GM full size clusters pre-2003 use what's called an air core motor. They have been discontinued for quite a while now. You can sometimes find NOS on eBay, but prices are over 4x over what they should be.
I have a 1999 gmc sierra and the kilometres only show when the key is in accessory. We know the following works, Speedo, check engine light, oil pressure and battery works. The PRNDL is delayed when going to P. The fuel level and oil gauges doesn’t read. I scanned the pcm and it shows the amount of fuel left in litres and percentage so I know the sending unit works…. The red battery symbol is on when key is to run position. Off position says Security. Is this a gauge cluster issue or wires from pcm to cluster? AllData doesn’t show fuel level sending wires from PCM to gauge cluster fuel gauge for some reason. When I plug the harness in with key on, the gauges all pin high and fall back down.
You're not going to see the fuel sending unit wires going directly to the instrument clusters on these Chevys. The fuel level information is sent over the low speed bus. It sounds like you're missing one of the ignition circuits, probably a blown fuse.
@@jeffescortlx fuses and grounds are all good. Sorry I should correct that, the gauges not working are fuel level and coolant temp. Watching your other video, you mentioned that could be the small circuit board not functioning? eeprom?
@@oxygen454the fuel and temp signals are received through the bus. The other gauges are not. But if you had no communication you would have other issues like the message center and warning lamps not reading correctly.
Jeff, I have an 02 Tahoe cluster that is possessed. Nothing works on the cluster except the check engine light, no gauges, no display. When the cluster is plugged in, random things happen like the rear AC blower will come on, the door locks will click, and there are odd noises behind the dash. The battery will eventually go dead, unless I leave the cluster disconnected. I tried reflowing the primary plug header and also the fluorescent display header, but it didn’t help. I purchased the truck dirt cheap, because the PO couldn’t figure it out, and he says the thing only has 75k on the clock. I’m going to try a known working cluster in it today, to see if maybe the issue is in the trucks wiring, as I don’t have a test setup. Any thoughts on this thing? If the good cluster checks out, I would like to send this possessed one to you.
The 99-02 full size are known to have a bad ground going to the cluster. I don't remember the pin # off the top of my head, but it's a black wire with a white stripe. Start with that.
What is the resting position for the oil pressure gauge when the cluster is turned on on the bench test but not connected to PCM? The one I have the pointer goes to 3pm mark :)
For the 99-02 the oil gauge has a analog input, on its own independent wire. I have a fixed resistor feeding it to trick it into thinking it has a sender plugged in. I take note of the needle position if a known good calibrated cluster, and reseat the needle to that position.
The cluster on my 2000 silverado the display and lcd screen works sometimes, flickers or freaks out sometime and is black (blank)most of the time. Would you be able to fix mine?? And if so what is the charge??
My dash cluster message center and the mileage part work when the want sometimes you just got to tap the cluster and they light up and sometimes it goes back out any thoughts on what would cause this
Can you do a video on a 99 f-150 cluster with tachometer for a 4.6l v8 I have a odometer with digital read that fluctuates on or off and mid way and sometimes it works well I heard it would have loose solder on the connection pins that give the signal to the display.
I'm having an issue of keeping my cluster lit up. I have a 99 sierra and the PRND321stays illuminated for about a minute after unplugging and replugging the cluster then it shuts off again. I don't see any bad soldier joints. Please help.
You talked about the gas gages on the 99-02 clusters. Are you familiar with the “hummingbird” effect in the 95-98(00) Clusters for trucks? If so, what is your thought on that? Have you repaired any older boards like those?
Interesting. I had heard of that as well, and some guys have replaced the motors, but they continue to do it. I’ll look further into it, as I know the newer steppers like what you use on these clusters don’t work for the older boards.
@@PeteyG708 being that brand new air core motors are not manufactured, they probably replaced a bad one with another used bad one and that is why the problem wasn't fixed.
Jeff, you seem to know these 99-02 clusters, can you tell me where to locate the 25020 chip for the odometer on this board. I'm familiar with the 03-06 clusters but cant seem to figure out where its located? Could you point me in the right direction. Thanks.
is there a way to recalibrate air core stepper motor because my cluster pointer are wrong. is there a tension you need to put to calibrate the needle to a zero or is there a other way ? thanks
Will a 2002 GMC HD 2500 instrument cluster work in a 2002 GMC 1500 Sierra? Trying to get a cluster with trans temp gauge. Or, can a trans temp gauge be added to my cluster?
@@jeffescortlx I've taken it to emissions once before, with no issue I passed. I cant see the silhouette to the check engine light how do I check a cel?
Hi. My oil pressure gauge has been bouncing back and forth for years now and now my PRND321 display is flickering . I have a video on my channel showing the issue. It has a brand new crate engine so its not the oil sensor. Is it more than likely the air core gauge going out or the sensor?
Do you know what D2 does on the circuit board? Mine shows 100 mV in both directions. Also do you know what size it is? I'm not sure how to tell. Thanks :) FYI ~ I have partial failure, the PRND, Speedo, tac, and possibly other guages don't work. Oil pressure, turn signals, and voltage appear to work (not sure how to test others without a bench setup).
100mV is not enough to turn on a diode. Sounds like you have a logic issue. Volt and oil are analog inputs. While the gas and temp come in through data.
@@jeffescortlx awesome help. My speedo and tac are also non functional. I am trying to find pin out and signal type for the connector so i can trace if is a problem with truck wiring or cluster. Do you know where i might find that info?
I've got a 2002 and i replaced the air core for the oil pressure, well i screwed up and messed it and another one up so the needle is now way off. and i've been looking and can't seem to find out how to re calibrate them
jeffescortlx yeah I have a 02 and a 01 cluster. I wanna take the tranny gauge out of one and put it in the other. Just curious what bulbs are they but I suppose I could just take one out and bring it in
I have a 2000 GMC and the oil pressure Gauge goes to the 40 PSI when I the turn the truck off. Is this cluster drawing power when the key is off. Thank you for your time and videos.
If both screens are flickering, you probably have a bad ground, it's a black wire with white stripe. When asking a complete stranger for free advice to fix your problem, a please and thank you go a long ways.
@@jeffescortlx sorry about that man totally forgot I really do appreciate your help and advice thank you.. I have been trying to get to the bottom of this with no luck... so your saying the ground is bad on the wiring harness that actually plugs in to the cluster? Thanks again man.
Yes, the 99-02 chassis have the cluster ground wiring terminating at a location that likes to rot. It's pretty common to see it go bad in locations like Minnesota where road salts eat everything up. Add a fresh ground to the cluster harness (black wire white stripe), wire taps work nice for this, there are some bolts behind the cluster that make good grounds. It's like a 5 minute fix, go for it.
Can u help me out ... I have a 02 Escalade and the speed needle doesn’t move and the mileage doesn’t turn either... but everything else works fine just those 2 things.....
Would you know why my fuel gauge takes over an hour to register fuel on a 2001 Silverado? I replaced the fuel pump and now it takes forever to show how much fuel is in the tank. Thanks in advance
Can the air core motors on these be "fixed" or do they need to be replaced? I have a cluster that the oil press. gauge is erratic at idle, but will move to a solid position once you are moving.
If it has lost it's fluid smooth movement, you can use a syringe filled with heavy oil and inject it down the shaft opening. Although replacement is a lot less messy.
I had read something about them using fluid to create resistance, but wasn't sure that applied to all motors. Thanks for info. Do you have a video about removing and calibrating the needles for these year? Seems the 03-07 models take all the glory in the repair scene and how-to lol.
Your right there isn't much info floating around on the 99-02. They are not as easy to recalibrate since they don't have a stop location that can be marked. Sorry I don't have any videos on this yet.
Is the recalibration strictly a "professional" type of deal or is it possible to pull off as a DIYer? Is it possible to attach needles while vehicle is running and compare to say OBD scan info to position them correctly?
I am curious if you know why so many of these can cause parasitic draw. It seems like everyone on the internet says they are the most common cause of parasitic draw in those vehicles. But why is that the case?
I loved the vid, more informative than any I seen for this yr. But, if you could slow down when you show the diod discolouration issue it'd help. No other complaints, ty for the help
Hey Jeff im having an issue i hope you can help with. I have a 2002 cluster just like the one in the video, i have removed the eeprom to correct the milage from my old cluster and i believe i have fried the eeprom trying to read the data. Can i use a 95202 eeprom to replace the old one? Not much info on finding out how to read those older chips.
If I remember correctly the 99-02 are a different eeprom than 03-06. Did you want to buy a pre-programmed one? I could dig around for one this weekend.
@@jeffescortlx because it's missing. The guy my friend got the Tahoe from had tried to fix it before he got it and upon inspection I found it and a cap missing. Found the replacement cap but having difficult finding Diode. It's one of them glass diodes.
@@shaunjeffries3136 the glass diodes are just used as polarity protection. Measure the physical dimensions and find a package size that fits. A diode good for a couple amps should be ok. Most of those only pass a half amp.
Hi Jeff, I just bought a used 2002 z71 chevy, not sure how I missed that some of my cluster lights weren't working :-(. None of my upper left corner strip or upper right corner strip as in this video lights are not working except turn signals in that area, everything else seems to work. Any ideas, or where I can send it for repairs? My gut is also telling (did this guy swap otu the cluster for something with less miles) :-(.
The 99-02 have user serviceable lamps, no need to send it out. Remove the back and just twist to unlock the sockets. Look for junk yard stock numbers written with marker to confirm if it's possibly not original.
That's typically a sign the previous owner found out it was cheaper to take a hammer to the warning indicator light then it was to actually fix the problem.
jeffescortlx awesome, I hadn't thought about just using the factory modules outside of the vehicle like that. I am contemplating trying to use an arduino and a CAN shield to do the same thing just for the fun of it, but I'm sure that route will be torturous at best.
That would be good for learning how it works. But for the quick and dirty a scan tool will work to. I also use a GM tech2 for bench comunication. It can do sweeps and turn on warning lights.
Luckily i have an autel maxisys so i can do the sweep with it, but the control freak in me really wants the ability to control them individually :-) It is nice to know that you can have the vci communicate with just the one "module" on the bus like i saw in a different video you put up. I wish i would have come across your videos earlier, i have bought quite a few reman clusters because i didn't know the causes of the common faults. In the last couple of years i've been self studying electronics design & repair and trying to apply it to what i do in my auto repair shop making a little extra money in the process (which is good because my one man shop barely pays its own bills lol). You should put together a video of your knowledge relating to automotive electronics repair, i would pay for that. I just wish there were some type of class covering clusters mainly, common faults and fixes, and general skills to pin down uncommon faults.
where can we get the motors for these clusters, i have searched with no avail. Also, is there any way to recalibrate them without a tech II? i want to change my needles out as they are very faded but dont want to change up the readings. Thank you, Brendan
jeffescortlx thank you so much! I know exactly why you got so many subscribers as you mentioned in a recent video. You post incredibly detailed videos and are always helpful. I hope your channel continues to grow.
Hi Jeff, I have been struggling with my 02 gmc sierra 1500 gauge cluster for months now. The speedometer and odometer are not working right now. When scanned with a computer it has diagnostic trouble code P0608 which says to check the wiring between the instrument cluster and the PCM. I have hooked up a multimeter from the PCM to the gauge cluster and the wire has continuity in it. I have taken it to a GMC dealership and they said that the speedometer fails their sweep test when they send a command to sweep the speedometer. They said it jumped straight to 50mph when it should sweep all the speeds slowly. They wanted to replace the stepper motors in the cluster. Should I replace the speedometer stepper motor? Any thoughts on why the odometer is stuck at 149k miles? Anything else to check? Its funny that the code pulls up for a bad wire connection between the PCM and cluster, but I'm leaning towards instrument cluster problems. thanks!
Sounds to me the cluster isn't seeing the VSS signal. That gen 99-02, when I sweep with my tech 2, will not do a full range sweep like the 03-06 do. So with it only sweeping up to 50-60mph doesn't alarm me. They use air core motors, not stepper motors, your thinking 03-06 style.
jeffescortlx if the cluster is not seeing the signal, any thoughts why there is continuity with a multimeter from the PCM and the Cluster? Do you think the PCM pin that sends the signal is bad? When the car is hooked up to a scanner it can see the vehicle speed, so I know the vehicles computer is calculating it correctly.
@@jeffescortlx I just barely tested my cluster in a friends truck and the speedometer and odometer are both working on my cluster. So you are right, the signal must not be making it to the cluster. My friend had to head to work or else i would have tried his cluster in my truck, just to confirm. I don't know what to think because I stretched my multimeter leads all the way from the wire connector at the PCM, to the wire connector at the cluster and my multimeter beeped with continuity. All I can think now is the PCM is not actually sending the signal through the pin, or there is just enough resistance or something on the wire causing the signal to fade out. Any thoughts?
Hello, i wanted to ask you a question. I have a 2003 Suburban another vehicle cut me off and I had to slam on the brakes I slammed them so hard that a rusted brake line burst at the exact same time my fuel gauge went to the line above "E" and the light came on. I thought that the level indicator might have got jammed because of the abrupt stop but my mechanic checked it used a new pump & sending unit and a spare cluster he had at the shop but the fuel gauge still reads at the line above "E" and the light is on. When you start the truck the needle looks like it goes down a notch to "E" the back to the line above "E" at time this occurred I had put 20 gals in the tank. Any ideas as to what might be going on? Thanks for any thoughts. Mac
The first thing you should do before you start throwing parts at it is hook up a scan tool. You can confirm the sending unit signal and run tests on the cluster. Since the Orange low fuel light is coming on it's probably a problem between the sending unit and ECU.
I love the videos! Having a 1999 Silverado when either directional is blinking my voltage gauge bounces just a little bit on every blink. Would that be the cluster or something else?

Clusters that use air core motors that have gas gauge issues are 99.999% the fault of the sending unit and or gas tank wiring. Not the air core motor.
my dash illumination is intermittent on left side of cluster. assuming are bad soldering joints?
The bulbs are not soldered in on 99-02, they are on a socket.
on my 99 silverado i remember the odometer being dead when i bought the truck, i pulled it apart soldered some broke/cracked connections, put it back in the truck and about had a stroke. Discovered the damn thing had 319,000 on it.
What did the previous owner tell you it had for miles when you bought the truck?
I bought my 2003 Tahoe because i thought had 130 miles but the cluster lights went off, so i found somebody to fix it and he told me he can put any miles he want on it and any body that knows about it can do the same, i felt bad cause the guy that sold me the truck could've paid someone to put 130000 miles to sell it and cause i wouldn't buy any car over 200000 miles, i hope those are the right miles
You ever think about swapping engines with the odemtor have the old engines miles still on there some people swap the engines out and dont put the engine miles on the cluster
@@Nelval573 were I'm located the odometer is supposed to show the miles of the chassis, not the engine. Replacing the engine is not a justification to roll back the odometer.
I had my cluster out earlier today to chase down an electrical issue that seems to be an inoperative BCM, and out of curiosity, pulled my cluster out to see why my Check Engine, ABS, and Brake lights have never worked since I bought the truck. Someone unsoldered and removed them from the board. Sigh. Any idea what LED should go in place of them?
It would depend on the make, model and year of vehicle.

It's an LED. A piece of electrical tape over it will do.

@@jeffescortlx oh I see it my bad. I don’t know how I missed that.
Love your videos man but I was wondering if you could maybe show a video on replacing gauge motors on a 99-02 gm cluster?👍
I need to see this video too i really somebody removed the light bulb for the check engine light
Question!!!
Where can I get the twist sockets for the replaceable bulbs for the 99-02? Mine has the Wagner PC194 bulbs which are soldered to the bulb sockets.
Someone had replaced one of mine because it was removable, but there are no identifying marks on the socket besides a 6 or 9↕️. It is grey. All the ones I've found online are the wrong size or have the locking tabs in the wrong place.
I've always had plenty of good cores to pull working ones from. Those bulbs usually last 300k+ miles. I've never needed to track down the socket part number. Sorry I can't help.
@@jeffescortlx your good. Yeah, I can buy the replacements for those pretty easily, but I'm afraid the bulbs won't come out of those either. One is blown in my cluster so I just figured why not go to LEDs. Multiple attempts buying sockets to no avail. They all twist too far past the contact strips on the board, if I turn back a little it won't be secure. Does no one change these over to LEDs properly? All I can find are the wrong darn sockets.
@@jonathanst89 I'm my experience most of those pre-assembled 194 LEDs only last about 90 days and then start flickering and failing. You can solder them in directly.
@@jeffescortlx I bought the LEDs separately from the sockets because I have a particular brand LED I always use thats never failed me on headlights, tail lights, turn signals. I agree though with that prepackaged junk, those paper clip contacts are just sad lol
I don't really want to solder anything, I'm not very good at it and I want to be able to easily go back to halogen or other LEDs. I'm just going to keep looking for the sockets, I know they're out there somewhere!
HI Jeff, thanks for sharing all of your awesome videos and help! I've browsed through several but cant find my issue. Have you seen a cluster in this 99-02 range that displays solid Security light, Low Fuel, and Battery light. But the truck starts and runs perfect (so I dont think it's Passlock), fuel guage shows empty when full, and also have an ABS and Airbag light. Then the security thing drains the battery dead over night. Someone in a forum said they swapped clusters and it fixed it, but my cluster solder looks great with no burns or anything unusual. Thanks so much!
For anyone else searching, this other video solved my security light, battery light, and low fuel light and guage problem. th-cam.com/video/KxGE8bPCGco/w-d-xo.html
Now I just need to figure out why I have an ABS and airbag light together.
This would be great to know. Mine does the same thing intermittently but when I put my foot on the brake pedal just enough for the brake lights to come on it all comes back to normal. And when I lose all those gauges and the lights come on I lose OBD2 communication because my gauge monitor loses connection. I’ve tried almost everything I can think of with no luck
Could you do something similar to this video but maybe tracing down why the speedometer and tachometer don’t work ?
It's usually from a damaged wire/ harness
@@jeffescortlx I’ve checked and rechecked the grounds. And if I did it right, I’m pretty sure there’s power/signal going to the engine speed and vehicle speed connectors. For those 4 prong connections to the needles for the tach/speed needles, should one of those be ground? With everything disconnected, one lead on A8, should I have continuity through one of the four slots?
@@jeffescortlx so tested more with the multimeter. With the engine running, A2 (engine speed signal) is getting a constant 6.15v, but revving the engine to increase RPM doesn’t change that voltage at all. I’m guessing it should increase voltage as the RPM’s increase?
@@m3talc0re The signals are based on frequency and not voltage. Can your multimeter read Hz?
@@jeffescortlx I don’t think so, I doubt it, though. I had my scanner connected to the OBDII port and it was showing rpm and vehicle speed in the live view.

Jeff, your videos are very informative. . I am replacing the needles in my 99 sierra cluster. 2 of my air core motors free spin like you e shown in your vids. In one, you used a syringe and oil to form them up. Can you tell me what setup you use to rejuvenate them? Than you, Bill Dalbey
This video here shows that process:th-cam.com/video/TLtDw_Sjh1o/w-d-xo.html
@@jeffescortlx thank you Jeff for your quick reply. I ended up going to a local you pull yard and checked used clusters until I found a motor for my fuel gauge and oil pressure gauge too. Ended up finding a much nicer face too. (Mine has all of the orange "warning" hash Mark's faded off. That's why I bought new needles off of ebay.) What type or grade of oil do you use to fill the air coils and is the syringe just pushing the oil into the housing around the pointer pin? Thank you again for your knowledge sharing and your channel.
Jeff, Sorry about the oil question. I went through your older replies to other folks and got the answer. I put my cluster back in my truck this evening. Calibrated all of my gauges and every thing worked fine. When I started the truck, my tach isnt working. I used a better face and moved my air cores that were functioning properly, 1 at a time, so as to make sure they went to the proper location. I took the truck for a drive. Used my GPS to check speedo. Everything is functioning except the tach. I pulled the cluster and re installed the motor to insure that it was seated properly. No change. Also, I used the fully functioning circuit board from my old cluster so my odometer would be accurate. The tach was fully functional before this. Where do I go from here?
@@williamdalbey4867 it's possible you installed the motor 180° off.
@@jeffescortlx , you were absolutely right. The motor for my tach was 180 degrees out. Thank you so much for your knowledge and willingness to share it.
Hi Jeff, I have repaired the solder joints on my 2000 Silverado cluster and I am trying to find a pinout to bench test the odometer display on the cluster only. Is there any way you could help me figure that out? Thanks so much I’m advance. Great information in your videos.
Why not just plug the cluster back into your truck instead of building a bench testing rig for a one time use?
jeffescortlx thanks for the reply. I brought the cluster to work with me to repair the solder joints and don’t have the truck with me. I was just hoping there were 2 pins I could supply power and ground to in order to test the odometer display by itself. Is that a possibility or is it way more complicated than that? If it is I’ll just wait until I get home with it and can plug it back into the truck. Thanks again.

Great video very informative.
I have a 99 Chevy that the odometer display will only show anything if I push the reset button very hard for about 30 seconds. I was just going to replace it, do you think it could be caused by the same issue. I’d take it in but I use my truck too much to be without it at all. I generally do all my own repairs. I’m no technician I’m horrible diagnosing. However I’m a good mechanic I can swap parts.
You probably just have fractured solder joints.

Is there a way to keep my Stability Control error from lighting up on my 2002 Escalade message center? The ABS/EBCM Modules are no longer available for it and I don't want to spend anymore money on it having it rebuilt.
I guess you would have to find someone to write you a modified file and reflash the module. But it would probably be cheaper to just have it repaired rather than hire a software engineer?
I see...I was hoping someone could point me to a wire I could open to cut the signal for that error message
There is not a one single wire for each warning message. They all share a serial data wire. If you cut that you loose everything.

If you're 100% sure you don't have a blown fuse it might be time to send the cluster in for service.
@@jeffescortlx checking fuses today after work saw a couple videos of a couple fuses to check if you can list them taht would also help
@@BRED23 I'm not sure what all the fuse box labels are. Some of them are labeled to be for the instrument cluster and some are not. I would recommend giving a look over all of the fuses, both under the hood and in the dashboard.
0 blown fuses cluster will randomly start working and the chime will sound when the cluster dies temp gauge seems to be completely dead now when the gauges work the PRND321 will not shine on but once the cluster “dies” gauges go off the PRND will turn on like normal
I’m sure my starter is bad and is on its way out will change that hopefully it works also looking into ground straps

I have a 1999 gmc sierra and the kilometres only show when the key is in accessory. We know the following works, Speedo, check engine light, oil pressure and battery works.

The red battery symbol is on when key is to run position. Off position says Security. Is this a gauge cluster issue or wires from pcm to cluster?
AllData doesn’t show fuel level sending wires from PCM to gauge cluster fuel gauge for some reason.
When I plug the harness in with key on, the gauges all pin high and fall back down.
You're not going to see the fuel sending unit wires going directly to the instrument clusters on these Chevys. The fuel level information is sent over the low speed bus.
It sounds like you're missing one of the ignition circuits, probably a blown fuse.

Jeff, I have an 02 Tahoe cluster that is possessed. Nothing works on the cluster except the check engine light, no gauges, no display. When the cluster is plugged in, random things happen like the rear AC blower will come on, the door locks will click, and there are odd noises behind the dash. The battery will eventually go dead, unless I leave the cluster disconnected. I tried reflowing the primary plug header and also the fluorescent display header, but it didn’t help. I purchased the truck dirt cheap, because the PO couldn’t figure it out, and he says the thing only has 75k on the clock. I’m going to try a known working cluster in it today, to see if maybe the issue is in the trucks wiring, as I don’t have a test setup. Any thoughts on this thing? If the good cluster checks out, I would like to send this possessed one to you.

What is the resting position for the oil pressure gauge when the cluster is turned on on the bench test but not connected to PCM? The one I have the pointer goes to 3pm mark :)
For the 99-02 the oil gauge has a analog input, on its own independent wire. I have a fixed resistor feeding it to trick it into thinking it has a sender plugged in. I take note of the needle position if a known good calibrated cluster, and reseat the needle to that position.

Hi. My oil pressure gauge has been bouncing back and forth for years now and now my PRND321 display is flickering . I have a video on my channel showing the issue. It has a brand new crate engine so its not the oil sensor. Is it more than likely the air core gauge going out or the sensor?

To find out if your cluster is drawing power with the key off, remove the fuse and replace it with your multimeter set to measure current.

Yes, the 99-02 chassis have the cluster ground wiring terminating at a location that likes to rot. It's pretty common to see it go bad in locations like Minnesota where road salts eat everything up. Add a fresh ground to the cluster harness (black wire white stripe), wire taps work nice for this, there are some bolts behind the cluster that make good grounds. It's like a 5 minute fix, go for it.

Hey do you you have a video of recalibrate a 99 Sunfire gauge cluster
Not a video no. Just put the needles back on in the same start position they were before you took them off.
would you tell me what is the wire that turn warning low oil level on when oil pan is low?
Do you still fix these?
Yes
Can the air core motors on these be "fixed" or do they need to be replaced? I have a cluster that the oil press. gauge is erratic at idle, but will move to a solid position once you are moving.
If it has lost it's fluid smooth movement, you can use a syringe filled with heavy oil and inject it down the shaft opening. Although replacement is a lot less messy.
I had read something about them using fluid to create resistance, but wasn't sure that applied to all motors. Thanks for info. Do you have a video about removing and calibrating the needles for these year? Seems the 03-07 models take all the glory in the repair scene and how-to lol.
Your right there isn't much info floating around on the 99-02. They are not as easy to recalibrate since they don't have a stop location that can be marked. Sorry I don't have any videos on this yet.
Is the recalibration strictly a "professional" type of deal or is it possible to pull off as a DIYer? Is it possible to attach needles while vehicle is running and compare to say OBD scan info to position them correctly?
Its just a matter of putting the needle back on in the correct position, only catch is you can't do it with the cluster off.
I am curious if you know why so many of these can cause parasitic draw. It seems like everyone on the internet says they are the most common cause of parasitic draw in those vehicles. But why is that the case?
In my experience is the 03 is the most common for draw issue, not the 99-02 style.

I have a 2002 cluster just like the one in the video, i have removed the eeprom to correct the milage from my old cluster and i believe i have fried the eeprom trying to read the data. Can i use a 95202 eeprom to replace the old one? Not much info on finding out how to read those older chips.
If I remember correctly the 99-02 are a different eeprom than 03-06. Did you want to buy a pre-programmed one? I could dig around for one this weekend.
jeffescortlx the chip has 42926 at the top and i believe st 9048 at the bottom. Not sure if the other chip will interchange?
It's been a while since I've messed with a 99-02 eeprom, I can't remember the details from memory, but can look into it when I get back in my office.
jeffescortlx if you would not mind that wouldbe greatly appreciated!
jeffescortlx not sure if you had a chance to check it out? Not trying to be a burden. Thank you sir.
I have an 01 silverado.The dash gauges will only work IF I depress the trip meter plunger
Any idea what went bad??
Fractured solder joints.
OK ,Thanks
Are you available to repair this unit?
@@thom9040 yes.
What would it cost??
@@thom9040 the link to my contact information is in the pinned top comment.
I'm looking for some diode info on a 03 Tahoe gauge cluster. How can I find the info to get a replacement?
How do you know it has a bad diode? What diode are you referring to? There are several.
@@jeffescortlx because it's missing. The guy my friend got the Tahoe from had tried to fix it before he got it and upon inspection I found it and a cap missing. Found the replacement cap but having difficult finding Diode. It's one of them glass diodes.
He must of had some clumsy hands to knock off those parts. It's just a general purpose diode, .7-.5v drop.
Ok when I looked for it in DigiKey there was almost 200 that came up. How would I go about figuring out which one it was?
@@shaunjeffries3136 the glass diodes are just used as polarity protection. Measure the physical dimensions and find a package size that fits. A diode good for a couple amps should be ok. Most of those only pass a half amp.
If I require your service how can I get in touch with you to discuss options.

Hi Jeff, I just bought a used 2002 z71 chevy, not sure how I missed that some of my cluster lights weren't working :-(. None of my upper left corner strip or upper right corner strip as in this video lights are not working except turn signals in that area, everything else seems to work. Any ideas, or where I can send it for repairs? My gut is also telling (did this guy swap otu the cluster for something with less miles) :-(.
The 99-02 have user serviceable lamps, no need to send it out. Remove the back and just twist to unlock the sockets.
Look for junk yard stock numbers written with marker to confirm if it's possibly not original.
What would be your pricing if id send you a cluster to get worked on? Got a 01 gmc 1500 and the display does the same thing.
$100
jeffescortlx can you email me? Dereknovack@gmail.com.
Can I put one like that on a 99 Chevy Tahoe ?
Yes
What if the “service engine soon” light and 4wd light won’t come on?
That's typically a sign the previous owner found out it was cheaper to take a hammer to the warning indicator light then it was to actually fix the problem.
Dang.. I’m repairing the odometer tonight and didn’t know if there was anything I could do for it. What about 4wd light?
@@adamcrawford9023 you'll have to do some trouble shooting to see what's going on.
Ok thanks
What setup are you using to drive the fuel gauge? They are bus controlled on these aren't they? Thanks
You are correct. I have a 2003 avalanche ECU&BCM in a box wired with pots for sensors. Talks to pretty much anything.
jeffescortlx awesome, I hadn't thought about just using the factory modules outside of the vehicle like that. I am contemplating trying to use an arduino and a CAN shield to do the same thing just for the fun of it, but I'm sure that route will be torturous at best.
That would be good for learning how it works. But for the quick and dirty a scan tool will work to. I also use a GM tech2 for bench comunication. It can do sweeps and turn on warning lights.
Luckily i have an autel maxisys so i can do the sweep with it, but the control freak in me really wants the ability to control them individually :-) It is nice to know that you can have the vci communicate with just the one "module" on the bus like i saw in a different video you put up. I wish i would have come across your videos earlier, i have bought quite a few reman clusters because i didn't know the causes of the common faults. In the last couple of years i've been self studying electronics design & repair and trying to apply it to what i do in my auto repair shop making a little extra money in the process (which is good because my one man shop barely pays its own bills lol). You should put together a video of your knowledge relating to automotive electronics repair, i would pay for that. I just wish there were some type of class covering clusters mainly, common faults and fixes, and general skills to pin down uncommon faults.
Sounds like your moving in the right direction, keep up the good work.

Not sure if you answer questions, but if you do....how much would this type of repair cost?
Depends on the year/make/model
where can we get the motors for these clusters, i have searched with no avail. Also, is there any way to recalibrate them without a tech II? i want to change my needles out as they are very faded but dont want to change up the readings.
Thank you,
Brendan
The older air core are not available new as far as I know, so you have to scavenge from good used ones. You have to calibrate with power on.
jeffescortlx with power on, with no data, do they go to their home position
@@brendan747 that's how I do it. You can set the needels with signal, as long as you know where it's supposed to point.
jeffescortlx thank you so much! I know exactly why you got so many subscribers as you mentioned in a recent video. You post incredibly detailed videos and are always helpful. I hope your channel continues to grow.
@@brendan747 thank you.
Does the cluster store the mileage information?
Yes.
I have a display from a 08 skidoo summit , would you be interested in looking at it.
Sorry but I'm backed up on repairs, don't have time to take on new projects at the moment.
How can I get in contact with u?? Would like u to take a look at mine as well..

Hi Jeff,
I have been struggling with my 02 gmc sierra 1500 gauge cluster for months now. The speedometer and odometer are not working right now. When scanned with a computer it has diagnostic trouble code P0608 which says to check the wiring between the instrument cluster and the PCM. I have hooked up a multimeter from the PCM to the gauge cluster and the wire has continuity in it. I have taken it to a GMC dealership and they said that the speedometer fails their sweep test when they send a command to sweep the speedometer. They said it jumped straight to 50mph when it should sweep all the speeds slowly. They wanted to replace the stepper motors in the cluster.
Should I replace the speedometer stepper motor? Any thoughts on why the odometer is stuck at 149k miles? Anything else to check? Its funny that the code pulls up for a bad wire connection between the PCM and cluster, but I'm leaning towards instrument cluster problems. thanks!
Sounds to me the cluster isn't seeing the VSS signal. That gen 99-02, when I sweep with my tech 2, will not do a full range sweep like the 03-06 do. So with it only sweeping up to 50-60mph doesn't alarm me. They use air core motors, not stepper motors, your thinking 03-06 style.
jeffescortlx if the cluster is not seeing the signal, any thoughts why there is continuity with a multimeter from the PCM and the Cluster? Do you think the PCM pin that sends the signal is bad?
When the car is hooked up to a scanner it can see the vehicle speed, so I know the vehicles computer is calculating it correctly.
Do you have have a different cluster you can plug in for testing?
@@jeffescortlx I just barely tested my cluster in a friends truck and the speedometer and odometer are both working on my cluster. So you are right, the signal must not be making it to the cluster. My friend had to head to work or else i would have tried his cluster in my truck, just to confirm.
I don't know what to think because I stretched my multimeter leads all the way from the wire connector at the PCM, to the wire connector at the cluster and my multimeter beeped with continuity. All I can think now is the PCM is not actually sending the signal through the pin, or there is just enough resistance or something on the wire causing the signal to fade out.
Any thoughts?
@@morgandurocher2023 What was the fix for the this?
We can't find you email button ... we'd like to send ya my son sons cluster... keeps falling on and off
You found it.
What type of diode was used?

Hey jeff my cluster speedometer gauge is not working and the mileage is staying same and not changing. Would you think it is the sending unit?
I would think so. Try to get your hands on a good scan tool to confirm before you start throwing parts at it.
jeffescortlx Hey I got a junkyard board and just put my eeprom on that one and I powered it up and now it is in km any ideas?
The cluster came out of a Canadian truck? The face probably read kilometers instead of miles per hour?
jeffescortlx That's what I thought at first but I powered it up before hand and it was in mph I'm stumped.
What about the gauge face of the parts cluster? Does it show 120 MPH?
That strange symbol is an alien attack message. Prepare! ;)
do you do repairs still? I have a cluster giving me peculiar issue. maybe you can help. hope to hear back from you.
I still do repairs yes.
jeffescortlx website I can checkout or email so I can get further info?

Hello, i wanted to ask you a question. I have a 2003 Suburban another vehicle cut me off and I had to slam on the brakes I slammed them so hard that a rusted brake line burst at the exact same time my fuel gauge went to the line above "E" and the light came on.
I thought that the level indicator might have got jammed because of the abrupt stop but my mechanic checked it used a new pump & sending unit and a spare cluster he had at the shop but the fuel gauge still reads at the line above "E" and the light is on. When you start the truck the needle looks like it goes down a notch to "E" the back to the line above "E" at time this occurred I had put 20 gals in the tank. Any ideas as to what might be going on?
Thanks for any thoughts.
Mac
The first thing you should do before you start throwing parts at it is hook up a scan tool. You can confirm the sending unit signal and run tests on the cluster. Since the Orange low fuel light is coming on it's probably a problem between the sending unit and ECU.
Thanks for your time and knowledge
anybody know what part i need to replace the motor for the oil gauge on 2001 tahoe
Oil pressure sending unit.
I love the videos! Having a 1999 Silverado when either directional is blinking my voltage gauge bounces just a little bit on every blink. Would that be the cluster or something else?
What if you have replaced several sending units? What could it be
Wiring or the cluster. Put a scan to on it run some sweeps
