Brake light wiring diagrams I do not wish for the third brake light to blink

What would cause my ABS and e brake light to stay on?

At some point in the last couple months the lower brake lights quit working. When I do press the pedal the brake light on top of the cab lights but the lower brake lights do nothing. The hazard lights and turn signal lights use the same bulbs and both of them work fine. I diagnosed it as a bad multi-switch Which I replaced a couple weeks ago but still nothing. I replaced all the fuses.

I haven’t used a test light on the wiring in the steering column. That would be my next step.

Any other ideas?

I'm trying to find the correct part number for my crew cab Silverado LT's driver's side brake harness. I tried replacing the bulb plug ends with aftermarket ones and now the brake lights and tail lights are reversed. With the headlights/tail lights on the brake light is lit. With the brakes pressed down the tail light is on. I wired it with the three wire plugs just like it showed but now it's backwards. I've switched the wire ends but still it doesn't work right and the tail lights and brake lights are backwards.
I am trying to find the correct part number to order a new harness completely. Mine has the three wires on the three larger ones for, 3157. Top brake/tail light, middle blinker, bottom reverse, then at the bottom is the smaller plug side indicator that I think was a 194.
The plugs are all brown and burnt pretty bad on both sides. So if you know and could what is the part number for the passenger side, also. I'll just replace the entire harnesses for both sides instead of worrying and trying to get the new sockets to wire in and screw the passenger side up also.
Thanks.

Thanks for your reply. I found after thorough digging and checking with my tester that the top brake/tail light uses all three wires on the new socket. The pink center hooks to brown and the blue hooks to blue. Of course the black is ground. But on the original second, blinker socket it uses two blacks and a blue. Those 2 black wires are connected together to continue the ground up to the top brake/tail light socket. The center wire on that one of my new one isn't used. So I dropped and taped up that center wire, took the black on the new sockets for both top brake/tail light and second blinker and connected them together, and using some spare wiring connected those 2 ground wires to the black ground going down the harness, which also hooks to the black side of the reverse light at the bottom.
I hope that explains it and I don't confuse you, lol. It looks like the reverse bottom only uses the outer 2 wires. Ground and hot, and center wire of it is the ground connected inside it's socket, also. So reverse bottom and blinker middle are only 2 wire sockets while the top brake/tail light is a 3 wire socket. The same ground continues to be used and extended for all 3 sockets.
Anyway, thanks for your help and advice. I looked at the part number you gave and it does look like the correct part number. Driver's side is 16531401 and passenger side is 16531402 in case anyone asks. It runs from around 2002 thru 2007 or so for that same harness I believe. If this gives me problems i'll change them both and forget changing socket ends. It's a big hassle that's for sure.

Oh, and the new sockets and old sockets have the same rubber bushing so I put them both on each socket so it seals tightly, although it was a bit hard to push in and twist. The aftermarket taillight lense I got was slightly thinner at the holes so the original sockets and these new ones didn't tighten up enough to be water tight. They are now. And thankfully I now have my 3157 LED's and sockets all brand new and working great.

My rear brake lights do not work. Bulbs have been replaced, brake light switch has been replaced, junction box has been replaced. Fuses have been checked all are good. Still no brake lights the brake light on the cab does work but no brake lights in the rear. Please help.

My brake lights on my chevy p/u do not work. I have backup lights taillights blinkers but no brake lights. I have ckd the bulbs changed the blk electrical circuit board in the rear. Also chkd all fuses and changed the one under the brake pedal. Help im at my witts end and driving dangerously.

Thanks deb

I have no voltage or fluctuating voltage going to the third brake light. It appears to be a short. I have recently replacedthe brake light switch and turn signal switch cluster. I cannot find an accurate wiring diagram for the brake circuit even though I have purchased Clymer and Haynes manuals for this truck. The regular bed brake lights work fine. It does not appear to b a problem in the wiring harness that runs to the rear speakers and brake light. There are no fuses being blown. Does anyone have a suggestion or a wiring diagram that includes the third brake light.

Thank you, this helps immensely

I have running lights, turn signals, and hazard lights, but no brake lights when the pedal is pushed. The fuse is intact, we replaced the brake light switch on the brake pedal as well, but the brake lights still will not turn on. We also checked the ground which is good.
