I feel like you just called out every issue with my truck 😂
Wow me too I have an 89 silverado. I already fixed the head gaskets. No more oil leak. But lol every other thing tho weird electrical issues. Like my speed Guage and miles gage only work when they want haha. I've replaced my back right bulb like 3 or 4 times only had truck like a year in 4 months. My wipers only work good on high, (I thought it was the blinker switch on the steering culum.
Me to 😅
Rite... same here haha
Oooooooooo😂😂😂😂😂
Of the problems you cited, I have only had to deal with the doors pins and bushings. But I have had a few other issues such as intake manifold gaskets that failed, causing an intermittent vacuum leak. Gaskets replaced at 240,000 miles in my 1994 Sierra K1500. I now have 270,000 on my pickup, and it still runs well. Solid and reliable.
So many of these trucks still on the road after 30 years. They dont build em like this anymore
NOPE. In 2005, (I was just retiring at GM) I saw a farmer friend's then future son-in-law's 2001 Silverado 1500 in my friend's driveway. That 2001's rear bumper had more rust showing than the rear bumper on my '97 K1500 GMC SLE----Being a GM worker, that pissed me off---FACT...
@@bobhoffman5581 So what happened Bob? Did GM start seeing dollar signs ( for their board of directors ) and decided to screw the employees and customers by cost cutting for the almighty buck? No more bailouts if they go bankrupt. They created the mess, let them clean it up instead of making the taxpayers do it for them. I’m not just talking about GM, but every car company in the world. I’d like to see what would happen if no one bought a car or have their car serviced for a year at a dealership. But that’s just a pipe dream. The dealers would find a way to live high on the hog by charging the taxpayers for their high lifestyles they’ve grown accustomed to. You can’t win. One could try I suppose, but the lawyers would bankrupt that consumer so fast that the person wouldn’t even have time to blink their eyes.
1993 C1500.
Wiper motor control: Intermittent interruptions with wiping. I disassembled the motor/controller board housing and discovered numerous broken solder paths on the circuit board. The repair was zero cost and zero parts. I just resoldered the broken electrical paths. Jumper wire may be necessary to add to the mix depending on how bad.
Body grounds: Yep. Front passenger body-to-frame and frame-to-engine replaced on passenger side engine bay. A year later I reworked the fuel filler neck grounding strap.
93 K1500 ext cab here...
I will eventually deal with the tail lights and my wiper motor/board.
Pulled engine months ago and sent short block to machine shop. They bored it 0.020 over and put flat top pistons in it. Block, crank, and con rods are the only original parts now.
906 iron vortecs, edelbrock dual plane intake, Comp cams 212/218 & .450 lift flat tappet, custom throttle body bored to 46mm w/ 18lb regulator spring by SPRPerformance, all dialed in by Brian @ TBIChips with a solid chip tune.
My machinists recommended an oil cooler delete for my setup, so that's what I did. Large/short filter screws onto block with small threaded adapter (sits about 1" away from front driveshaft).
Those factory oil cooler lines were why the under and driver's side of my engine bay was caked in oil and dirt.
If your blinkers are blinking fast or shorting out your trailer lights REPLACE THE TAIL LIGHT BOARDS!! Learned this the hard way

#6 starter failure, these trucks had a serious lack of heat shielding around the starter.
#7 fuel pump, internally mounted in the fuel tank and if you're like me and have the optional 32 gal tank, trust me when i say you dont want that pump failing you when the tank is full!!!

Just take the bed off…. Or cut an access in the bed if it’s a work truck
289,364 miles and still holding up. have too love these types of trucks. easy to fix when u know what's wrong with them.
Those miles give me hope on mine i just did a whole rear end frame restoration 1996 silverado k 1500 with 139,179 miles with roughly 37,000 on rebuilt trans strait pipe 5.7 350 things a beast love it, ill keep it good till i pass it on to my son
@@rtgflamez2249 and please look 👀 into classic car 🚗 insurance it’s cheaper and better coverage. Also you get guaranteed value instead of blue book 📖 value. At this current time OBS Chevys are being valued at 10-20k depending on condition of course. But please look into classic car insurance you pockets and you will thank me later.
I started to have a small electrical issue but it happened once and never happened again and after watching this, I'll check my ground wires. Thanks!

Also be ready for replacing the fuel pump and the rear end if you run big wheels and tires on the stock 10 bolt. After 17 years of driving my 2000 Escalade (1st gen), I've had to replace those items a couple of times with 249,000 miles on the odometer. Thanks for not calling it an OBS.
Owned my 88 for 10 years or so now and this top 5 isnt kidding.
Great video, I recently got a 1988 Chevy Scottsdale and the biggest issue right now is the door bushings. Do you have a in depth video for replacing them?
I have some of these problems with the 3 of my OBS Chevys.
But let’s be honest you really don’t see as many fords from this time period still driving around... they do exist but rare
And fortunately these OBS chevys are all over the place in SC
And have a low market value compared to up north because we don’t have much rust in SC and these trucks are all over the place
I see the Fords all the time as well as the Chevys. I see the Dodges as well
Don't see nice ones very often by me up north these days
Fuel Pumps and door handles also. I second the damn circuit boards too. Had the truck 2 years and already gone through 3.
Just bought a 95 yesterday in the light rain, turned wipers on and they wouldn't turn off, and both doors sagged when open. Thanks for the tips!
Quick update to wiper motor, there was a callback on them. Got mine replaced free at gm shop.
If the door's still saggin, after changing out the door bushings, open door and stick a 2x4(one I used was about 4 ft) into lower hinge, and push the door like your going to shut it, take the board out, see if it shuts better, if not try it again, or until you get it where you want it.
i have a 1998 gmc c1500 just did complete front end work ,this is truck run kick 1000% azz
I have 1996 K3500, owned sine 2001 with same body style. As of 2020 Yes to 3 of 5 items ... wiper circuit board, oil leaks and rear taillight circuit board. The Ground and hinges are still good. 160k miles orig 7.4 liter engine, rebuilt 4l80e. I have replaced fuel pump twice and intake manifold gasket once. Over half of the miles it is towing and/ or had slide in truck camper.
+dave edvalds Thanks for the feedback, we appreciate it!
got a 92 c15 350 tbi replaced distributor, spark plugs/wire, rebuilt tbi, fuel pump, iac, map sensor, tps sensor, knock sensor, egr still good, and good grounds but I still have a miss in it somedays better than others
Not bad, my rear dif is sloppy need to change out
I have a '89 Chevy K1500 i want to remove the front torsion bar suspension system and replace with leaf spring suspension , my question is , is this possible and what's the full parts list ?
Would the ground strap cause it to misfire constantly?
What manual transmission and differential oil does it take? I have a Chevrolet Cheyenne pickup year 1995, 305 tbi 5.0-liter 8-cylinder engine, 238 thousand kilometers and I don't have the vehicle manual, they are the same models from 1988 to 1995
more videos about GMT400 platform....awesome videos ;)
I don’t know if it’s just me or it’s very common issue but I just sold my old work truck last week that was a 95 extended cab that would slowly leak power steering fluid throughout the year. I then bought a 94 single cab project earlier this year to ls swap it that also leaks power steering fluid. And now I just bought a really rare 98 k1500 crew cab last month that leaks puddles of power steering fluid when I make I turns. Swapping the power steering hoses on these trucks would fix it for me but having 3 trucks with the same exact issue couldn’t be a coincidence right?
Put some lucas stop leak in there if you dont wanna change hoses yet, stopped mine from leaking but it was small.
And make check timing with a light
Best replace rear tail light boards with new LED that comes with lense. I have many of the Dorman replacement boards sitting on a shelf- junk.
Pop in and out the pins and bushings.....a freaking nightmare 😫
Great video ! You look like one of my favourite boxers, Angel Manfredy !!!
Every time I stop at a parts stores on my 94 K1500 for stuff that shouldn't fail, the clerk always says: "Yep, that's common for those trucks."
Wiper board
Wiper arm
Door hinges
Window regulators
Ground wires
So much rust.
Rusted braked lines
Rusted out fuel tank
Rusted cab corners
And so on
Ally of that rust is from where you live I live in Alabama and have a 1997 k1500 and it doesn’t have a single spec of rust on it all original( we get zero snow and don’t have salt laying everywhere
Great video! I have had all of these common problems.
+Steven Kappes Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
Mine almost hit 500k now transmission giving me he'll I will be trying to upgrade a 2500 4x4 tho would be nice to get a 4 door tho :-(
#6 on the 350 engine, the pot metal water connector coming off the rear of the intake manifold that goes to the cabin heater. What a crappy design.
replace with a 3/4 plumbing fitting
Some of this affect 96+ and for the wipers that's usually only on 97
6 is the ecm plugs into the distributor control module sensors.. plug-in knowing to get worn out and starts up and stalls out and stubborn to restart again
+Blair Joseph Bernard Thanks for the feedback!
those grounds that are broken lead to front bearings to go bad.
You forgot the oil cooler lines. They always have issues and leak on this model. I have replace mine so many times then I care to count.THanks for the video.
Delete them
If a chassis ground is melted but intact is that an issue?
no radio or heat controls display dark. might be ground. didnt think of that one cool i hope.. now to found out how to test 4wheel without takin the actuater out. to be sure its engauging
Good information, thank you.
+Otsenre s Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
For me it was cracked heads, stripped gear on the distributor cap, fuel pump, and ABS smooshy brakes on my 97 GMC Sierra K1500.
+James M Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
What you do about your brakes?
@@chaotic476 bleed the abs pump/module assembly and properly adjust your drum brakes... this helps a whole lot!
You forgot fuel pumps, especially on the 88.
My 91 k1500 has a very small missfire I live in California it always passes smog at cold start you can bearly feel the missfire but once the truck has warmed up you can feel the truck vibrate. I have driven the truck with the misfire since 2013 and it drives fine at highway speeds just missfires at idle stuff I have changed to the truck are spark plugs, the wires, whole distributor, motor mounts and transmission mount, my rear differential took a shit at 140k Miles too, fuel filter change with injector cleaner and a tbi rebuild, one thing I did notice is that my thermostat is a 160f and oe is 190 I believe throw out any ideas I really want to fix this truck it's in perfect condition z71 150k miles summit white with the burgundy interior and it has a sunroof
I found people describe the same issue after doing "custom" exhaust work on their truck; something about the timing on the last cylinder.
Try changing your ignition coil
I have a '89 K 1500 and it had the SAME problem this is how I fixed it = Change the - Engine Temperature Control Unit - it cost 16 dollars - it sends messages to computer about temp , if unit is bad it will send wrong numbers to the computer and then the computer will send the wrong settings to the throttle body injectors and your motor will run either too rich or too lean - And that my friend is your vibration . And it's a simple fix. the other plus to this is you will get better millage when fixed. Good Luck Rick Out.
I had a 94 throttle body fuel injected 2Dr Blazer and if I remember correctly that slight misfire is normal if it’s as slight as I think 🤔 yours is if it’s not throwing codes with the old school code let thing and u hit it with the timing light 💡 and everything is perfect 👌 I believe your all good sir. I now have a 98 2Dr Tahoe same truck 🛻 just as u know it’s Vortec fuel injected but I prefer the TBI easier to fix less electrical B.S. and in my opinion the TBI 350 block set up is more reliable so kudos to you sir if I could I would switch back to TBI or straight carb any day those things are bullet proof literally. The only reason they changed was for the EPA and to be more competitive in the MPG aspect of marketing but more so I believe the EPA other than that the 350 block is one of the greatest inventions known to man.
What is the tool for the spring to change the pins and bushings
Just a small spring compressor that you can get from amazon
Vice and zip ties.
i have a 92...yes the wiper board is a problem ..most is broken solder joints ..motor will last the truck...how i know retired from delco ..have the same motor an board in my 95 transport ,,easy fix..never had any other problems like you said but i know tail lights are one of them
My old '95 k2500 has every one except the tail light board.
(Plus alot more you didn't cover, lol)
Still a dependable truck with almost 200k on it, when I sold it.
+dm7097 Thanks for the feedback!
Calling a GMT400, K1500 a car is a cardinal sin (jk). Regardless thanks for the video.
FUEL PUMP FUEL PUMP FUEL PUMP
Not even dude that's your problem you probably always run your truck on E
@@miguelplascencia6093 nah its a very common issue on this things lmao 🤣
"Special tool" you mean zip ties.....
Surprised you didn’t mention the spider injectors
What’s the point in flipping the air filter cover upside down?….I’ve seen it heard the theories tried both ways….couldn’t tell a difference.
1989 c1500 here. Anybody have a problem with a shudder when at highway speeds and gradually increasing?
Hey Chilly, my 89 k1500 does this but not all the time. I'm guessing driveshaft u joints. If u got a bunch of miles maybe Check those
My 1991 5.7 v8 2nd gear shift hard. Is that a common problem? Anyone have suggestions?
Thanks
My 95 does it too when it's cold
You need a new valve body, common on these.
Well I'll be DIPPED
Correct order and everything
You have 2 of these vehicles videos
I like the rims on the thumbnail truck
Yep my 95 does the same crap! Lol
I have an 89 Chevy and have 3/5 problems😂
Pretty much everything you said has happened to my truck. Lol
Now I wanna damn fix mines haha
3 major problems: 10 bolt rear end, 4l60e, vortec intake gaskets.
The vortec trucks have significantly more running issues than the TBI trucks from what I have seen.
dont frgt rocker panels
+john Harrison Thanks for the feedback!
Yeah you are right on haha.
oxygen sensor bigy
🤣🤣 these trucks have problems with them you guys are crazy these things are tanks
+Jonathan Requena Thanks for the feedback!
Lol what about the shitty "intake vent" or the horrific clear coat job!?
funny you have 2 top 5 issues with these trucks why didnt you just do top 10 lol
No wonder Chevy went broke they can’t sell any
This truck actually sold well lol
They sold millions of these trucks lol idiot
these sold crazy well
They are one of the oldest trucks you still see on a daily basis to this day. I love my lifted 94 K1500
73-98 chevy/gmc trucks. Biggest hunks of junk i ever owned. Glad i got rid of all mine. Most of them went to the crusher
Kept buying em?
Why junk?
Im positive theres ALOT more than 5 ! Maybe 5 dozen. #1- being a "chevy"
Not Just Chevy But All Vehicle Manufacturers Produce Junk.
Expensive Junk....
Ok “Linda”
