I'm a big guy got it off in under 15mins waited till night to do it now just pick up a new one tomorrow just needed to find the tools that work I preferred a small flathead to take clip off and harness and no damage observed. Thank you for the video does help alot otherwise I'd just send it to a shop.
Amen to these trucks being good trucks!! I got a 98 and an 04. Yhe last two decent gens! My 04 is my baby but I'm really falling in love with this 98 lately!
People, PLEASE READ. Thanks for the video. I just replaced the switch on my bosses personal 88 GMC 1500. I didn't follow troubleshooting 101. There were no brake lights at all, so I assumed it was the switch. After I went through a couple hours of cussing the GM engineers trying to fit my big self under the dash to replace the switch, there still wasn't any brake lights. I didn't realize there was a 30 amp fuse under the hood for the brake lights and it was blown. Make sure you check ALL the fuses. The third brake light didn't work because both bulbs were blown. So before, you crawl under the dash and attempt this, use a test light or volt meter to verify at different locations.
+Rick P on a newer one there is a fuse under the hood, on a 88-94 its under the dash, The rear brake light circuit is independently fused, i guess for a trailer. I burned up a bunch of these switches from high use, I blame traffic for it, so its nothing new for me lol I replaced it 3 times
I know this is 8 years ago but just bought a 95 1500 ( wt) that was kept in a garage since new and just rolled 100k miles. It’s so straight and. Original paint is almost flawless. Every since I sold my 97five years ago I’ve been looking and I found this gem. Prly swap to a 350 one day but for now I can deal with the 4.3.
ya TBI is real easy 4.3 to a v8. Think you can even reuse the same harness just change the ECM Memcal on the truck and then. of course 350 TBI, Distributor knock sensor etc v8 van shroud. I remember Dude who came by had to sell his old truck for a van.. And I was like "yea but its a 305" and he had good point "Atleast its a v8" Yea.. 100% 305 works
This switch also effects Transmission( Torque Converter Lockup) and your cruise control use. Check here first it’s cheap and easy and the only problem the most of the time.
@@ausexplosion1550 there are 3 contacts in the brake light switch. One for the brake light, one for the tcc lockup and one for cruise control. The switch has to send signal to all 3 components so that they know when brakes are being applied. If the tcc doesn’t release when brakes are applied it will burn up the converter or stall the vehicle. Same as cruise control, if the brake switch doesn’t send signal to the cruise control, then when you are cruising down the road with cruise control on and you press the brakes the vehicle wouldn’t slow down and stop cruising. The surge problem (rpm hunting) issue I had in my truck wasn’t resolved until I replaced the brake light switch. My tcc would constantly lock and unlock while cruising and make the rpm’s jump up and down. I had a bad contact in the brake light switch.
The video was a great assist. I have a 94 sierra and the switch was replaced by a mechanic when I bought it 2.5 years ago. I read a great forum piece that said if your 3rd light was out but hazards still work then it is the switch. I watched the video and was able to replace the old one in about an hour. It is not easy to get to but if you watch the video and feel up around there you will get the idea. My old one had a c clip and not a spring clip. I put the c clip back on for now but will change to the spring clip soon.
Yea they had some with a round disc like clip that slide over the pedal rod. Too bad I could not get a better shot of how the clip goes on. You have to remove the steering volume, which I Have a few times and the access to that switch is awesome!
Damaged shifter mechanism from pulling too hard when brake interlock solenoid won"t release from PARK has led me to this switch.The switch is easily repaired. Carefully release locks around switch body and one in middle and remove switch cover.Remove the small copper plate and using a pair or crecent wrenches,bend the small plate very gently in direction of pedal shaft wear.Bend just barely past 180 deg.Push wear spot toward pedal shaft.You're just taking up the play.The contacts can be removed for cleaning but looked great after 321k.Put tiny spot of grease each side of copper plate and worked great! Getting clip off was a bitch and wire harness could be 3in longer.Hope this helps!
That clip is a booger! I have a 94 Suburban with an aftermarket alarm that is taking up a lot of space under the dash. I'll try the pick since it worked for you. The other thing, I swear I used to hear a relay click when the brake lights came on, but the schematics show no relay on the burb.
Shannon Looper yea, large pick tool is what you need, Small does not work too hot! I did not have one in years past, With some creative wiggling its easy to get it off, I had this switch on and off in 10 minutes, I never did it so fast! When I took the column out a few years ago, WOAH big room! I have about 30 new GM brake light clips, I should sell some. The 94 burban does not have the relay on the firewall?
everything on my truck is starting to fail. my step dad left me with a mess when he passed away. a few months ago. the blower fan went out, breaks light switch failed, the power steering return hose started to leak, and the interior lights wouldn't shut off one day so i just pulled them. besides that i had to put the bed back on and get a new tail light harness. also had to put a side mirror back on. its a pos truck but it drives better than my car because the trans failed on it. i just have bad luck with vehicles.. every year is a struggle.
When I have my hazards on, and I press the brake pedal at the same time, My hazards stay solid and stop flashing. Also when I’m driving, my combination flasher relay buzzes & activates on and off like I have my flashers on even tho I’m driving.
The round one found on the 2000 Tahoe limited... is No fun. I found that using a long flat screwdriver and pressing from the center outwards. Will cause the Clío the get loose, also trying to pop it upwards helps too. Motorist pulled up next to me on a red light and let me know that I didn’t have brake lights. I was wondering why he was getting so close to me 😂
Video was really helpful for understanding the clip. I didn't have lockpicking tools since I'm not a burglar but I was able to reach over the column with my hand and rotate it to the position needed to just apply enough downward force and it came out.
Your KEY piece of information here is , there is a RELAY in the brake light circuit! It's NOT on the firewall, but I will forgive you for that mistake. It's inside the "relay center", a black plastic housing mounted on the top of the front left wheel well. If if turns out to be my problem, I will send you kisses.
Mine has the relay on the fire wall. Other years maybe had it on the inside. Its not my mistake. You need to Figure out your own wire diagram they changed alot of on these trucks year to year. or with different options
@@jonyates3918 You need to tap into I guess the brake light wire and ground it. Then the wires run to the back And probably a Key on 12v source. U need a diagram to tell which wire is what
Not sure if they had a relay on the fire wall over the brake booster like this one has Or maybe they added that when they added the 3rd brake light in 1993 or 4 I forget
I need to do this exact job and I'm dreading it! What were the engineers thinking when they hid that part way up there...a moving part that would have to eventually be replaced.
Do you know if the brake light switch controls getting the transmission in and out of park or just simply turns on or off brake lights?? My brake lights wont work on my 98. Fuse and bulbs are good. Only haven't checked relay or switch. Plan to fix this week so any pointers or tips would be great! Any ways to test switch or relay? Taillights, blinkers and hazards work just no brakes on all rear lights.
We're can you get a replacement lock ring for the break switch. I went to my local automotive stores and they gave me a wild look. Never seen it before. And your right that clip ring hard get off
Get a long pick set and you can work the clip off, You need 2 pics I used like a semi curved one that's on a angle and I think a straight or a 90. Just make sure u dont poke yourself or any wires. Ya I changed this switch like 5x they dont last You can take them apart and clean all the contacts and sometimes they work again
One of my brake lights doesnt work at all ! Just one wire is good , bulb is good ! I dont know whats wrong with it any idea, my truck is a 1992 chevy cheyenne
Well.. unplug the switch connector if the lights go off most likely its the switch. If they still stay on the relay could be sticking or you have a bad short somewhere
Supposedly you can push the parking brake and if the dash brake light gets brighter, it's not your parking brake switch. It might be the fluid level or pressure differential switches.
What are the symptoms of a bad brake switch? I have an issue with my 95 where the 3rd light turns on but the other brake lights won't turn on when pressing peddle. All the other lights work as far as reverse and running light
+thesmoothone Brake light switch is going to kill them all. I think the rear tail lights have a fuse to protect them independently, as in towing a trailer and the trailer shorts out. That. or check the ground by the rear of the frame on the drivers side. Don't RULE out bad circuit boards on the tail lights either. Of course check the bulbs, i bet you did that already
Great video. Thanks for posting. You just saved me a ton of work, I just pulled and managed to replace without to many cuss words.. Ok that's a total lie. It's a bitch but I got it done.
If is hot like it is here I would of cussed like 800 times. But I know its cheaper doing it myself, the job will get done and no one will crash me (I hope) and I wont get pulled over for not having working brake lights. The people around here don't even tell you "Your lights don't work!" Because so many drive junk with 2-3 ALL OUT BULBS, Busted out lights. And there are U pull junkyards everywhere to get a replacement!
Ghetto Wagon my friend thanks for your video I have a question I have a92 Chevy 1500 and only my left brake light doesn’t work I already switch light bulbs and nothing it turns on when you have lights on but if you press Brake pedal it doesn’t light up
could be a bad fitment at the switch or you are using garbage new switches because the quality of everything is poor now. Also check the condition of the harness and connector pins that go into the switch. Also check the brake light relay if your model has one they can do bad But you would need to verify that the circuit works to the relay need a diagram.
My early 94 Chevy is a different issue I have brake lights,turn signals, reverse lights, license plate lights and hazard 4 Way flasher lights, but the 3rd brake light does not work..
No but its just 2 bolts under the dash and 4 at the fire wall optional.. unbolt the steering shaft. The steering column comes right out I usually remove them when I need to work on them, take them apart inside in the AC, fix it, reinstall.
tonychevyobs 1500 I'm now installing my third switch. My brake light switch leaves my brake lights on all the time. Replacing the last one for the same thing about the lights staying on. The reason why I replaced it the first time was that when I purchased my GMC the brake lights didn't work at anytime.
I have a 1990 GMC Sierra. I don't have any tail lights, turn signals or brake lights. Ground seems good. Power to the back is there. However, when I hook up the camper trailer the lights on truck are dim, but brake lights work on camper. help!!!!
Good video. Be careful if you do "drop the steering column" if you need to reposition yourself and grab ahold of the wheel your truck may jump out of park and slam into a tree with you upside down In the floorboard like mine did. Not the best most complete instructional.
I just installed one on my 94 K1500, and it works, but there seems to be too much play and wobble so It doesn't accurately read it, any suggestions to get it to work right?
+Legal Zephyr You are saying the brake light switch moves too much? in what direction? side to side or forward and back? If its side to side the clip is not on all the way. Front to back play, the switch could be just crap, mine moved too much like that and that's why it worked when it wanted to Its a weird fitment, if its loose the brake switches contact wont close. What brand switch? ACD? or aftermarket
It is an Autozone brand, "Duralast" i'm pretty sure, and the play is side to side, I put in a washer, it fixed it a bit, but now i have to angle it a certain way for it to work 100% of the time. And I don't know how to do a permanent fix.
I believe it was the round one. Well, at least the end was round. Also, The guy I bought it from gave me a Delco one, should I try putting that one in?
I like the delco one over aftermarket, I always used delco, I only replaced this switch twice and its been USED in Northeast traffic! On n off the brake I think most 94s use the square clip. It locks on to a small groove that you can barely see. When the steering column is out its real easy. Legal Zephyr
I am having the opposite problem as thesmoothone. My third break light on my 97 Silverado IS working but the tail lights on the bed do not. I have park lights and turn signals but no break lights. The previous owner had a trailer light set up which I've disconnected and gone back with factory hook up but nothing has changed. All fuses and bulbs are good. I'm puzzled since the break light and park light are the same bulb; and since the park light works it's not a connection issue. Any ideas?
I got a 94 Chevrolet silverado k1500 and when I barely push on the brake maybe 1 inch.. I have brake lights but if I push all the way down they go completely out... any suggestions?? maybe try new switch??
It could be worn out. The problem with this switch was not the contacts, the brass contact piece on it was just bent from use. It engaged when it wanted about 1 out of 10 brake applications. Get a AC delco switch they seem to last the longest. Made in Mexico!
replaced switch, now when brake pedal is pushed the lights come on for about the first third of travel and then goes out when pedal is fully depressed. Any idea what is going on?
Switch man not be adjusted right on the push rod, Also make sure that the clip is locked on right. Some brake light switches I noticed the brass colored piece that slides over stud on the brake pedal is sometimes not bent well. If you bend it so it fights tighter the brake lights are more sensitive. I had a "bad switch" that needed just a bend and it worked again perfect.
My yukon Brake light don't work but my trun signals work fine. I went out and bought a brake light switch,I'm having a hard time installing it. Please help
how are you having a hard time? what is making it hard? the kind of clip I had wasn't like this one it was meant to never be removed... I have to remove all the steering wheel and at the end I was able to take the stupid clip off but it was hard... what is making hard on your end?
If only one tail light is not working.....could break light switch still be out??....I replaced bulb housing and all bulbs on driver side but only works periodically. Had stealing column replaced due to auto theft earlier in year.
if you have an old chevy may want to check the taillight board, Take both tail lights out, plug the working side into the non working side and visa versa The board is different as in the fitment but the connector fits. If the problem travels side to side you need a new board on the non working side. Or you can just use a test light make a pin, stick it in the connector behind the taillight and make sure the correct wire lights up the test light when the brakes are applied. There is a ground by the frame on the drivers side near the bumper. that can get crappy. Also there is a connector for the taillight harness around the same spot which can get corroded or damaged. Check that out for a good clean pin fitment.
I replaced the board on the now working after new bulbs made no difference. I will clean that ground up......I saw that earlier today as well and connector.......I will work those two areas next. I appreciate your input.
I have an 88 chevy silverado c1500 and my parking brake light keeps turning on my dash but the parking brake is not engaged. Do you have an idea on what it could be?
i got a 98, brake lights stay lit up wont dim when off the brake, turn signals dont work or reverse lights checked fuses and ground would brake light switch be the problem?
+mike beas If the lights stay lit all the time the switch could be sticking. Unplug the connector at the switch see if the lights turn off. If they do, most likely the switch is bad. I am not sure about a 95+ truck as they changed the wiring but make sure the brake relay is working correctly as well.Test it with battery power and a volt meter.
+Ghetto Wagon thanx o got it fixed. Apparently my luck is bad enough that both circuit boards on the taillights went out at the same time. I changed them both after putting brake lights switch, turn signal switch, and relay. A lot of time and labor for such a easy fix. Thanx for the info though.
Unplug the switch connector, if they go off it may, if the switch is the problem that is creating the short. That or the relay could be shorting out. if. You have trailer wiring, check out all that in the back for shorts to ground. Alot have some aftermarket T connector that connects between the chassis harness and the taillight harness. Cheap kits fail
im wondering. my brake lights sometimes stay on. if i lift back on the brake pedal, they go off. they dont always stick on..but i cant see whats happening going down the road, just if it happens when im parked but i can guess. My truck is an 89 c1500. could this still be the issue, or is that something else entirely?
I have a 89 c1500 & my brake lights stay on constantly even after I let go of the pedal.. I had to disconnect my battery to keep it from draining it. Could this be the reason ? TIA
@@GhettoWagonwhere is this relay located? (I've got 1988 k1500) Frustrated beyond belief...... I've got a wiring schematic, but it's not that helpful for me, other than wire colors. Another question, there's three bulbs in a taillight. The top bulb (single filament) never lights up...since I have no brake lights, is this the bulb that should be lit? Thank you!
Bottom bulbs on the tailights are for the brakes signals. 1988 wont have a relay on the fire wall think they added that when they put a 3rd brake light later on But maybe its there, Relay on the fire wall by the brake booster @@coeneschamaun1735
I have a 96. Your vid helps. I would add...everything happens after the clip comes off. The switch for the 96...looking at it...one would think "how in the world does this come out?". Believe me this is the worst design for maintenance imaginable. That clip is above the switch and its mount....you might be able to see it with one eye and a light just in the right angle. What a joke. This is what makes the shade tree guy cuss at modern engineering.
I could see only the bottom of the switch but I used the feel method with the clip. It came off easy but was a bi.ch getting back on (the clip). I also wasn't sure where the unit clipped on to but I moved it around and figured it out.
Thanks. I think I have to change this bugger again! These new parts do not last. Even AC delco. :( I lose lights @ half brake pedal. bad fitment maybe Ill have to take apart the switch and fix it
yea dorman makes a kit. 13808 Dorman. I The clips suck really. go get a used one or seach any other parts store even Napa I have a bunch of GM clips in my hoard.
Not really sure what you are saying The switch should clip onto the brake booster push rod. Put the switch on the peg, rotate the switch so its on the brake booster rush rod, then install the clip. The switch moves forward and back just a small amount to activate the lever inside the switch.
Blackhawk5656 Weird. Never knew they had a OBD2 code for that. Searched it, Yup. There is a code for it. It triggered the CEL? or was it a hidden code. I see it starts with a "p" so I assume it threw the CEL. I believe the switch when I took it apart had TWO circuits in it, Best I would guess is that maybe one leg is dead? So the lights work but its not sending a signal to the PCM. I dont deal with OBD2 vehicles too much. OBD1 is the best . I think if You had a fancy scan tool like a GM TECH 2 or a high end snap on it would have a table you can check for inputs and the PCM would register if the brake switch is on or off. The tech 2 I used to use had all sorts of cool stuff!
+Ghetto Wagon yeah I'm guessing that its just not sending a signal to the pcm. which is fine as long as my lights work. I have to replace my egr valve though
Nahh I just used the brakes alot. NYC traffic for years Now here in moronville, 5 min long stop lights. Current probably burns em up. OEM one was made in Mexico too back in 94
I dont think they were the made in Mexico parts can be hit or miss. Should of seen the pile of ac compressors I sent back. All were made in Mexico none were even worthy of use. Just slapped together wrong clutch. Locked solid. Now nothing is even made in mexico. Not China. USA/ Canada parts were the best can't argue with that. (Now hardly any exists) Japan parts were also very good Australia same. Mexico was just the land used by corporations in the US to exploit Mexican workers paying them less for the same job that used to be in the States all to fit a cost and they profit more. Now they use China for that.
unless you have child sized hands, your going to have to drop the steering column. Took about an hour from start to finish. Zero fun factor. Damn engineers.
Well with that kinda thinking you probably wont be able to fix it. Let me know when you figure out out a way to light up under the dashboard with about 1/2 inch or less space to work to get the switch on and off
Does this switch effect the dashboard lights? Each time I step on the brakes, my dashboard and radio lights come on/dime and no brake lights...turn signals are not working either in the rear
shouldn't that sounds like you may have a broken ground. There are light grounds in the back by the frame behind the right wheel wheel and some grounds in the front by the radiator support on either side Also check the ground straps from the body to the frame Engine to frame engine to body ETC
@@GhettoWagon so I changed out the whole wire harness and now just the left lights works lol And when u turn on all lights, everything lights up in the rear reverse etc thanks for the ground tips doe I'll check
I'm a big guy got it off in under 15mins waited till night to do it now just pick up a new one tomorrow just needed to find the tools that work I preferred a small flathead to take clip off and harness and no damage observed. Thank you for the video does help alot otherwise I'd just send it to a shop.

@@jonyates3918 You need to tap into I guess the brake light wire and ground it. Then the wires run to the back And probably a Key on 12v source. U need a diagram to tell which wire is what
have no power to brake light switch thinking relay dont know witch one under hood 1988 chev 3/4 ton 4x4 fuse is good any thoughts?
Not sure if they had a relay on the fire wall over the brake booster like this one has Or maybe they added that when they added the 3rd brake light in 1993 or 4 I forget
I need to do this exact job and I'm dreading it! What were the engineers thinking when they hid that part way up there...a moving part that would have to eventually be replaced.
Just did this...took about 45 mins. It's big balls but not impossible. Thanks for your help!!

Its easy to get to when the stirring column is out.
Do you know if the brake light switch controls getting the transmission in and out of park or just simply turns on or off brake lights?? My brake lights wont work on my 98. Fuse and bulbs are good. Only haven't checked relay or switch. Plan to fix this week so any pointers or tips would be great! Any ways to test switch or relay? Taillights, blinkers and hazards work just no brakes on all rear lights.
Having this problem how did you fix it
We're can you get a replacement lock ring for the break switch. I went to my local automotive stores and they gave me a wild look. Never seen it before. And your right that clip ring hard get off
Get a long pick set and you can work the clip off, You need 2 pics I used like a semi curved one that's on a angle and I think a straight or a 90. Just make sure u dont poke yourself or any wires. Ya I changed this switch like 5x they dont last
You can take them apart and clean all the contacts and sometimes they work again
It's NOT a "break switch".
And YOU'RE right (NOT "your right") would have sounded better, like you attended grade school.
One of my brake lights doesnt work at all ! Just one wire is good , bulb is good ! I dont know whats wrong with it any idea, my truck is a 1992 chevy cheyenne
You think I have to switch mine
My problem is that when I hit the brakes the brakes lights stay on (any ideas)
Well.. unplug the switch connector if the lights go off most likely its the switch. If they still stay on the relay could be sticking or you have a bad short somewhere
Supposedly you can push the parking brake and if the dash brake light gets brighter, it's not your parking brake switch. It might be the fluid level or pressure differential switches.
Thats only for ABS problems.
@@GhettoWagon what's ABS?
What are the symptoms of a bad brake switch? I have an issue with my 95 where the 3rd light turns on but the other brake lights won't turn on when pressing peddle. All the other lights work as far as reverse and running light
+thesmoothone Brake light switch is going to kill them all. I think the rear tail lights have a fuse to protect them independently, as in towing a trailer and the trailer shorts out. That. or check the ground by the rear of the frame on the drivers side. Don't RULE out bad circuit boards on the tail lights either. Of course check the bulbs, i bet you did that already
Did you ever find o what it was mine is having the same problem
Great video. Thanks for posting. You just saved me a ton of work, I just pulled and managed to replace without to many cuss words.. Ok that's a total lie. It's a bitch but I got it done.
I only cussed twice while doing it. That has to be a record
If is hot like it is here I would of cussed like 800 times. But I know its cheaper doing it myself, the job will get done and no one will crash me (I hope) and I wont get pulled over for not having working brake lights. The people around here don't even tell you "Your lights don't work!" Because so many drive junk with 2-3 ALL OUT BULBS, Busted out lights. And there are U pull junkyards everywhere to get a replacement!
I totally agree, thanks for standing on ur head while videoing this! Kudos man👍👍👍
this video is not for 88 to 98 the switch is different under 94 there is no clip
Ghetto Wagon my friend thanks for your video I have a question I have a92 Chevy 1500 and only my left brake light doesn’t work I already switch light bulbs and nothing it turns on when you have lights on but if you press Brake pedal it doesn’t light up
My brake lights stopped working I replaced the switch they worked for about a month then stopped working again. Any thoughts ?
could be a bad fitment at the switch or you are using garbage new switches because the quality of everything is poor now. Also check the condition of the harness and connector pins that go into the switch. Also check the brake light relay if your model has one they can do bad But you would need to verify that the circuit works to the relay need a diagram.
My early 94 Chevy is a different issue I have brake lights,turn signals, reverse lights, license plate lights and hazard 4 Way flasher lights, but the 3rd brake light does not work..
Check out the ground on the frame in the back. Drivers side by the bumper
@@GhettoWagon ,I didn't think that was it, because it has brake lights that work, but the light on the back of the cab the 3rd brake light does not.
I don’t understand how u got that camera down there I damn near ripped my truck apart trying to get me and a light under there
Need to remove more stuff. Remove the lower dash plate and the column bracket
Do you have any videos of how to lower steering column?
No but its just 2 bolts under the dash and 4 at the fire wall optional.. unbolt the steering shaft. The steering column comes right out I usually remove them when I need to work on them, take them apart inside in the AC, fix it, reinstall.
thanks just got my new switch
tonychevyobs 1500 I'm now installing my third switch. My brake light switch leaves my brake lights on all the time. Replacing the last one for the same thing about the lights staying on. The reason why I replaced it the first time was that when I purchased my GMC the brake lights didn't work at anytime.
What exactly was the issue that led you to find out it needed this switch ?
What does the brake light switch do? energizes the relay to do what? Light the brake lights
@@GhettoWagon .... I know that... I've read that it also will keep the vehicle locked in Park while idling after driving... So that's why I asked...
@@poppagrouch4781 Cant on these. They had no interlock on these old Chevy's
I have a 1990 GMC Sierra. I don't have any tail lights, turn signals or brake lights. Ground seems good. Power to the back is there. However, when I hook up the camper trailer the lights on truck are dim, but brake lights work on camper. help!!!!
Good video. Be careful if you do "drop the steering column" if you need to reposition yourself and grab ahold of the wheel your truck may jump out of park and slam into a tree with you upside down In the floorboard like mine did. Not the best most complete instructional.
Set the E brake
I just installed one on my 94 K1500, and it works, but there seems to be too much play and wobble so It doesn't accurately read it, any suggestions to get it to work right?
+Legal Zephyr You are saying the brake light switch moves too much? in what direction? side to side or forward and back? If its side to side the clip is not on all the way. Front to back play, the switch could be just crap, mine moved too much like that and that's why it worked when it wanted to Its a weird fitment, if its loose the brake switches contact wont close. What brand switch? ACD? or aftermarket
It is an Autozone brand, "Duralast" i'm pretty sure, and the play is side to side, I put in a washer, it fixed it a bit, but now i have to angle it a certain way for it to work 100% of the time. And I don't know how to do a permanent fix.
Legal Zephyr
It could be just a crappy molded switch. Did you have the PITA square clip originally or the round washer looking clip?
I believe it was the round one. Well, at least the end was round. Also, The guy I bought it from gave me a Delco one, should I try putting that one in?
I like the delco one over aftermarket, I always used delco, I only replaced this switch twice and its been USED in Northeast traffic! On n off the brake I think most 94s use the square clip. It locks on to a small groove that you can barely see. When the steering column is out its real easy. Legal Zephyr
I am having the opposite problem as thesmoothone. My third break light on my 97 Silverado IS working but the tail lights on the bed do not. I have park lights and turn signals but no break lights. The previous owner had a trailer light set up which I've disconnected and gone back with factory hook up but nothing has changed. All fuses and bulbs are good. I'm puzzled since the break light and park light are the same bulb; and since the park light works it's not a connection issue. Any ideas?
Ezekiel 9:1 did you ever find out what it was mine is the same problem
Check your tail lamp circuit boards. It's the part where you plug all your light bulbs into. I had to replace mine not to long ago.
Thanks for the video man! haha we are going to try to do this in 9 degrees!
Ive done it when it was cold. Its easy with a pick took to pop the clip off
How do you remove clip please go into detail with that
Pry it with a pick tool on the hooked end. its easy
I got a 94 Chevrolet silverado k1500 and when I barely push on the brake maybe 1 inch.. I have brake lights but if I push all the way down they go completely out... any suggestions?? maybe try new switch??
It could be worn out. The problem with this switch was not the contacts, the brass contact piece on it was just bent from use. It engaged when it wanted about 1 out of 10 brake applications. Get a AC delco switch they seem to last the longest. Made in Mexico!
Tim Baker
Yea I hope it fixes it The fitment is crucial for the switch to work, it engages in a weird way
+Ghetto Wagon just replaced it about 30 mins ago.. and it's works like new now! appreciate it!
Will this fix cruise control problems as well
If the brake light is causing it
My rear brakes lights are stuck on . Even when I unplug the switch could it be the same thing
not the switch
replaced switch, now when brake pedal is pushed the lights come on for about the first third of travel and then goes out when pedal is fully depressed. Any idea what is going on?
Switch man not be adjusted right on the push rod, Also make sure that the clip is locked on right. Some brake light switches I noticed the brass colored piece that slides over stud on the brake pedal is sometimes not bent well. If you bend it so it fights tighter the brake lights are more sensitive. I had a "bad switch" that needed just a bend and it worked again perfect.
My yukon Brake light don't work but my trun signals work fine. I went out and bought a brake light switch,I'm having a hard time installing it. Please help
how are you having a hard time? what is making it hard? the kind of clip I had wasn't like this one it was meant to never be removed... I have to remove all the steering wheel and at the end I was able to take the stupid clip off but it was hard... what is making hard on your end?
If only one tail light is not working.....could break light switch still be out??....I replaced bulb housing and all bulbs on driver side but only works periodically. Had stealing column replaced due to auto theft earlier in year.
if you have an old chevy may want to check the taillight board, Take both tail lights out, plug the working side into the non working side and visa versa The board is different as in the fitment but the connector fits. If the problem travels side to side you need a new board on the non working side. Or you can just use a test light make a pin, stick it in the connector behind the taillight and make sure the correct wire lights up the test light when the brakes are applied. There is a ground by the frame on the drivers side near the bumper. that can get crappy. Also there is a connector for the taillight harness around the same spot which can get corroded or damaged. Check that out for a good clean pin fitment.
I replaced the board on the now working after new bulbs made no difference. I will clean that ground up......I saw that earlier today as well and connector.......I will work those two areas next. I appreciate your input.
Yea NP chck if you have power and ground from the connector. If you have trailer wires check out that too I don't have trailer wires.
Thanks !
I have an 88 chevy silverado c1500 and my parking brake light keeps turning on my dash but the parking brake is not engaged. Do you have an idea on what it could be?
Jaime Tale If the light is dim lit, its a ABS code. IF the truck does not have ABS, probably its loosing brake pressure somewhere.
Ghetto Wagon It is dim and does not have ABS. I'll get to it now thanks man!
I had to replace the connector on my 97 silverado, some wires worked loose, could you list the color order for the connector? Thanks, Mike
Did you find out the order I’m needing them as well I have 96 k1500
i got a 98, brake lights stay lit up wont dim when off the brake, turn signals dont work or reverse lights checked fuses and ground would brake light switch be the problem?
+mike beas If the lights stay lit all the time the switch could be sticking. Unplug the connector at the switch see if the lights turn off. If they do, most likely the switch is bad. I am not sure about a 95+ truck as they changed the wiring but make sure the brake relay is working correctly as well.Test it with battery power and a volt meter.
+Ghetto Wagon thanx o got it fixed. Apparently my luck is bad enough that both circuit boards on the taillights went out at the same time. I changed them both after putting brake lights switch, turn signal switch, and relay. A lot of time and labor for such a easy fix. Thanx for the info though.
mike beas
I forgot about those boards. I should pickup a few GM ones
I got a 92 Chevrolet Silverado c1500 and the break lights stay on when the truck is off will this fix it ??
Unplug the switch connector, if they go off it may, if the switch is the problem that is creating the short. That or the relay could be shorting out. if. You have trailer wiring, check out all that in the back for shorts to ground. Alot have some aftermarket T connector that connects between the chassis harness and the taillight harness. Cheap kits fail
Fernie Escobedo
im wondering. my brake lights sometimes stay on. if i lift back on the brake pedal, they go off. they dont always stick on..but i cant see whats happening going down the road, just if it happens when im parked but i can guess. My truck is an 89 c1500. could this still be the issue, or is that something else entirely?
My break lights won't go off on my truck is this the problem
Was it a lunch break? My lights never take breaks because I have BRAKE lights!!!!!!!
I have a 89 c1500 & my brake lights stay on constantly even after I let go of the pedal.. I had to disconnect my battery to keep it from draining it. Could this be the reason ? TIA
unplug the switch. if they still stay on probably have a stuck relay
@@GhettoWagon thanks for the info. Ima check it out later today.
David temoxtle did it work for you ?
@@GhettoWagonwhere is this relay located? (I've got 1988 k1500) Frustrated beyond belief...... I've got a wiring schematic, but it's not that helpful for me, other than wire colors. Another question, there's three bulbs in a taillight. The top bulb (single filament) never lights up...since I have no brake lights, is this the bulb that should be lit? Thank you!
Bottom bulbs on the tailights are for the brakes signals. 1988 wont have a relay on the fire wall think they added that when they put a 3rd brake light later on But maybe its there, Relay on the fire wall by the brake booster @@coeneschamaun1735
We have a 1996 GMC SIERRA the break lights work when it's not running but when you start it we have none. Can someone tell me what the issue may be
BRAKE lights!!!!!!
I have a 96. Your vid helps. I would add...everything happens after the clip comes off. The switch for the 96...looking at it...one would think "how in the world does this come out?". Believe me this is the worst design for maintenance imaginable. That clip is above the switch and its mount....you might be able to see it with one eye and a light just in the right angle.
What a joke. This is what makes the shade tree guy cuss at modern engineering.
Its REALLY easy to get at when i had the steering column out. I was all "Woah look at that Clip access!"
I could see only the bottom of the switch but I used the feel method with the clip. It came off easy but was a bi.ch getting back on (the clip). I also wasn't sure where the unit clipped on to but I moved it around and figured it out.
Very good video! Thank you.
Thanks. I think I have to change this bugger again! These new parts do not last. Even AC delco. :( I lose lights @ half brake pedal. bad fitment maybe Ill have to take apart the switch and fix it
did you take the lower dash piece off?
+Jake Beauchene (Defender34) I dont think I did, I may have in the past but it did not help,
I got the clip off but it broke I can't find a replacement clip at advanced
yea dorman makes a kit. 13808 Dorman. I The clips suck really. go get a used one or seach any other parts store even Napa I have a bunch of GM clips in my hoard.
removing or replacing this does what ? sorry don't really and i want to know
Thank you!!!!
I let my 10 year old do it his hands fit right in there
Lets go child labor!
Nice ride
Its pretty trashed now. It was nice
i’m stuck on the part to take off the switch from the plug
anybody got tips?
I have a 1994 chevy silverado and I've got a new brake light switch but it's all moving together how do I stop the brake light switch from moving???
Not really sure what you are saying The switch should clip onto the brake booster push rod. Put the switch on the peg, rotate the switch so its on the brake booster rush rod, then install the clip. The switch moves forward and back just a small amount to activate the lever inside the switch.
Now if I can get my reverse lights to work
you knocked PRND switch at the column. White thing. If you move it all one way and cycle the gear shifter it will auto adjust
I'm having same problem no reverse lights or brake lights??
Any One Know Why so Many Wires? on 1987 & Earlier they just Had Hot In & Switched out = Simple!!!
Brake light on passenger. Not working and no signal at all 92 silverado 1500
My 94 Silverado makes a buzzing sound when I hit the brakes....
Any chance it's coming from that switch?
t.y.helpful video
Be helpful if I knew where TF this was located. I need to replace mine now and can't find it
Follow the brake pedal
Can't even see if that guy is working on the trunk or where?
code reader says I have a bad switch but my lights are fine? any idea?
+Blackhawk5656 Nope. Never heard of a brake light switch throwing a code
+Ghetto Wagon its throwing a code on mine I guess. it says stop lamp switch under the definition
Blackhawk5656
It must be new! What kind of vehicle what year?
Blackhawk5656
Weird. Never knew they had a OBD2 code for that. Searched it, Yup. There is a code for it. It triggered the CEL? or was it a hidden code. I see it starts with a "p" so I assume it threw the CEL. I believe the switch when I took it apart had TWO circuits in it, Best I would guess is that maybe one leg is dead? So the lights work but its not sending a signal to the PCM. I dont deal with OBD2 vehicles too much. OBD1 is the best
. I think if You had a fancy scan tool like a GM TECH 2 or a high end snap on it would have a table you can check for inputs and the PCM would register if the brake switch is on or off. The tech 2 I used to use had all sorts of cool stuff!
+Ghetto Wagon yeah I'm guessing that its just not sending a signal to the pcm. which is fine as long as my lights work. I have to replace my egr valve though
Does it say made in Mexico, that's probably the problem
Nahh I just used the brakes alot. NYC traffic for years Now here in moronville, 5 min long stop lights. Current probably burns em up. OEM one was made in Mexico too back in 94
Youre an idiot for that comment.
@@Pnwliving3392 fuck off if ya don't like it
I dont think they were the made in Mexico parts can be hit or miss. Should of seen the pile of ac compressors I sent back. All were made in Mexico none were even worthy of use. Just slapped together wrong clutch. Locked solid. Now nothing is even made in mexico. Not China. USA/ Canada parts were the best can't argue with that. (Now hardly any exists) Japan parts were also very good Australia same. Mexico was just the land used by corporations in the US to exploit Mexican workers paying them less for the same job that used to be in the States all to fit a cost and they profit more. Now they use China for that.
This is not the brake light switch for a 91 sierra
Ya its probably a little different on those
@@GhettoWagon Well the description says "88-98 GMC Sierra" 91 Sierra falls in that category.
@@anthonytravis1420 Ya but its the body style of truck. Its a similar switch similar procedure. They changed alot of these over the years.
unless you have child sized hands, your going to have to drop the steering column. Took about an hour from start to finish. Zero fun factor. Damn engineers.
No my hands are huge I can get the part on and off just fine.
my light don't go off now wtf
Changed it and the lights don't go off? Maybe the switch is bad. Or the relay is bad.
Terrible I can't see anything thanks
Well with that kinda thinking you probably wont be able to fix it. Let me know when you figure out out a way to light up under the dashboard with about 1/2 inch or less space to work to get the switch on and off
IT IS NOT "very, very easy"!!! Fibber.
Its not very hard. I learned what to use and I get em out in 5 mins
Does this switch effect the dashboard lights? Each time I step on the brakes, my dashboard and radio lights come on/dime and no brake lights...turn signals are not working either in the rear
shouldn't that sounds like you may have a broken ground. There are light grounds in the back by the frame behind the right wheel wheel and some grounds in the front by the radiator support on either side Also check the ground straps from the body to the frame Engine to frame engine to body ETC
@@GhettoWagon so I changed out the whole wire harness and now just the left lights works lol And when u turn on all lights, everything lights up in the rear reverse etc thanks for the ground tips doe I'll check
Did your relay under the hood start buzzing?
no
