Braketurn signal help.docx -
I replaced the brakes with A/C Delco heavy duty semi metallic with new sensor and pads. A whole bunch of warning lights when off. Had the truck towed to the dealer will be inspected Monday. That photo is not from my truck but you get the idea. So WHAT TROUBLES ME ASIDE from the lights and tow. Is the inside drivers pad was worn to the metal the rest were about 40% left. The brake pads were super easy to change. Remove 2 cotter pins, remove 2 retaining pins, the pads slide right out after slowly pushing the calipers back in. Easy brakes I ever replaced. I have replaced 50 sets or better since I was 16. The sensor a little bit of a pain but what electrical item isn't at the connector. Slides right back in on the pad side good design on Chevy's part. Truck: 2019 High Country 1500 6" Rough Country lift and 35" Fury County Hunter R/T sitting on 22's. Just under 25k on it. I saw a thread about pumping the pedal to 3/4 then fully depressing and repeating until full pedal pressure is achieved before starting the vehicle this may take several times pumping up the brakes before it works. Same thread also talked about clearing codes then restarting. I wish i had thought of that prior to having to towed. I was tired I guess.

I took a trip to Louisiana Sunday night and on the way back I noticed that my cruise control was not working when I stop to get gas I walk to the back of my truck and the brake lights are still on even with the key turned off my immediate thought was that the brake switch was bad After replacing it I found out that it was not the Brake switch so my second thought was that maybe having recently have pulled a trailer that the trailer pin plug may have been shorted out I disconnected it and that was not the problem either I then began checking fuses all the fuses are good and even when I remove the brake light fuse the brake light still stay on the only way to get them to turn off Is to disconnect the battery I am at a loss of what it could be please help -
Hi I have a 2001 GMC 1500 sierra and I’m having trouble with my cruise control. I think the problem is and I don’t know if anyone else has had this problem but recently I changed all my bulbs to LED bulbs. And on another post I read that somebody said that if you have a brake light out sometimes the cruise control won’t work on certain year Trucks. So I was wondering if anybody had this problem as far as maybe the LED bulb itself will prevent the cruise control from kicking in? Thank you

Hi I have a 2005 Silverado base model singlecab, ever since I got the truck the brake lights haven’t been working (except for the 3rd brake light) I’m going to say it’s not the brake light switch since cruise works and turns off with depressed brake pedal, 4 ways work and light up brake pedal, I never found a single blown fuse in the inside and outside box, when connecting a trailer the brake lights work on the trailer, can anyone help my find the problem?

I have a 2014 Silverado. The dealer installed my cap and made all the connections when the truck was new. Last month when the brakes are applied or the left turn signal is used the dome light flickers. Any ideas ? Thank You

I have a 2003 gmc sierra 2500HD i am totally ballfed as to why i have no brake lights, i tossed the LED's that were on it and re-installed new candesant 4" sealed round lights. in the beginning when i bought this truck i didnt notice it had no brake lights, my 360 check was lacking some from excitement and dog tired from driving 150 one way miles in a saturn that would only run 50 mph. i get it home and after several people passing me telling me i only have one brake light, i start diagnosing and checking every wire on it. the reverse light didnt work nore did the back up signal and the left rear brake light, so i bought a resistor set for the leds installed one on each side, still no help, next i bought a flasher module still no help, soi decided to install candasent and still no help, next thing i did was cut the installed harness that had the led resistors. i wired directly over to the lights through the factory connectors , now i have running lights with lights on , no brake lights not even the 3rd brake light, turn signals work, i've checked and replaced all blown fuses . so just to have brake lights during the day i wired the red wire to the brown wire using the running lights as brake lights. i have searched every where on the frame for the connector block, apparently mine does not have one. the harness runs in one big loom from cab to rear of chasis, then splits off to the blue and grey connectors. i have a tool box bed on it, i can see clearly from one side to the other, even pulled the spare . any ideas how i can get brake lights ? if i connect the red to green and yellow i have brake lights, but problem is my blinkers act like hazards when in left or right position. what could be the problem? I do know the LEDs shorted out and blew fuses, the left side had burned out and the right side was hot , not warm. why in the world would any one want to ground out their power ? Led's are Crap and a hazard in my book, your literally ground- shorting your power out on the system just to run low powered bright lights. could I have a bad flasher again? when this is fixed i'll talk about the wihining i'm hearing

My brake light switch has been giving me troubles. Turns out the guy who owned the truck before me had a metal washer between the switch itself and the little clip that holds it all in place. I was told that screwed up the switch that was on the truck when I got it -- after seemingly working fine for years. So, I replaced the entire thing and tossed the metal washer. Went fine for a while until I was at the bank one day, and couldn't get the truck into gear until I "cheated" the system and started the engine with in in neutral. I fiddled with the new switch and checked the connections (it's hard as hell to get to, btw), and couldn't replicate the problem again and the brake lights started working, so I move on. Fast forward a few months, and it happened again. I installed a little mirror on the back of my tailgate so I could monitor at least the middle brake light while driving. Sure enough, it would work sometimes ... but mostly not -- like 80/20.. I replaced the brake switch again. Figured, what the heck -- $10 part. Now, the brake lights work almost all the time (since now I'm checking quickly each time I press them). HOWEVER, the lights seem to not come on like 1% of the time. Overall, I suppose that's a decent success rate -- but not one you'd want for your brake lights, right? Very odd. Seems to happen when I'm cruising at about 45, then I flick my turn signal and then press the brakes -- like three of the four times the brake lights haven't come on, it's been after I'd activated my turn signal. And the other time was immediately following a misfire where I had used my turn signal. Does the functionality (or lack thereof) even make any sense? Any other times I've have intermittent working brake light switch, it's been closer to like 50/50. Lastly, I think back to the metal washer that used to be there. Obviously, the previous owner obviously put it there for a reason, right? Do you guys think a washer (not metal -- perhaps plastic or rubber/nylon) might do the trick? Or is the problem likely old wiring that needs to be looked at? -
I have a 2015 Sierra 2500HD, 4x4, 6.6L Diesel, Crew Cab SLT. I have been rebuilding the front portion of the bodywork due to collision damage. I have it pretty much back together, but it has a couple of electrical quirks that I cannot seem to diagnose. I would appreciate any help y'all can provide. First of all, anytime the battery(s) are connected, the brake lights stay on. All of them. Two bulbs on each side, and the high-third light. Even when the key is out, the doors are closed, and the truck is locked/armed. This does not have any effect on headlights. I can turn those on/off normally. When I turn on running lights, the small marker lights on the side of the taillight housing come on as they are supposed to, and the 2 main bulbs go brighter (or the second filament turns on), as they are supposed to. This seems like a pretty simple relay issue, or a wire being crossed somewhere. Trouble is, I cannot find anything labeled anything like "Brake Light" in any of the 3 fuse panels (under hood and dash side panels). I see headlights, turn signals, etc, but nothing for brake lights. Where can I find the relay for the brake lights? Or, does anyone have a wiring diagram that shows the path of that circuit so I can check it for shorts? The second problem is bigger, but probably easier to diagnose. The damn thing won't crank at all... The On/Acc position on the switch lights everything up normally, but when you crank the key, the instrument panel goes completely dark. When I removed the ECM to replace the broken bracket I found a small dent in the back cover. It didn't look big enough to cause internal damage, but maybe it was. I also noticed that the 30A fuse in the underhood fuse box was burned out for the ECM power supply. Just another indicator that there was a major short in there somewhere. I'm just hoping that whatever damage caused that didn't also burn out other ignition components... I am now trying to find a replacement ECM, which is a 2015-specific part. Its visible from ACDelco, but is apparently on permanent backorder... Anybody have an idea for where I can find an ECM for this year? Or whether I can use the ECM from a 2014 LML on my truck?

My brake lights stopped working on my 96 Silverado Z71. I checked bulbs, and they are fine, so I replaced the brake light switch under the dash (major PITA). Still don't have any brake lights. At least I know it has a good brake light switch! It had a trailer connector in the tail light wiring, but I've already removed that with no effect. Any other thoughts from anyone? -
I have a 2014 sierra with blue reverse lights and blue license plate LEDs just wondering if I could put blue LEDs for the brake lights and if it's legal to do or not

Hi I have a 2003 Silverado 1500 4x4. Two symptoms: 1) When the truck is off the hi-beams indicator flickers or comes on. 2) When the truck is on, the rear brake lights (the top bulb of each side) stay on whether braking or not. The CHMSL (center high mounted stop light) responds to braking normally. All other functions of the truck are good. No trouble codes from my basic OBD2 reader. Fuses are all good, however a mouse ate a hole into the top level of my underhood fuse box. After removing the fuse box shroud I found a nest and removed it. He ate the insulation off one wire and left two other wires connected by just one strand. I taped up the former and butt spliced the others but the repair had no effect. I also unscrewed the instrument cluster to see if he maybe set up a home behind there but all was clean. I tried to follow the repair procedure in the shop manual: I can't do a "Lighting Systems Diagnosic Check" because that requires a scanner that will talk to the BCM. I did disconnect the stop lamp switch and all brake lights went out, so the procedure suggests replacing the stop lamp switch. So that is what I'll do. Any better ideas? (P.S. I'll never eat in my truck again. All you need to do is drop one french fry between the seats and you will have a mouse condo in no time.)
