Buddies trucks brake lights aren't working third brake either.. Running lights work just no brake. Replaced the brake switch. Any ideas????

 

Bump.. Anybody?

 

Fuse maybe or all bulbs burned out

 

Bump ... I have an 03 and replaced switch all fuses and bulbs still nothing

 

I had this happen a few times check the wires that go to the tail lights under the truck or if he has a Plug for a trailer that could be bad also.

 

I have just the right brake light not working. It isnt the bulb. I hear that there is a tail light circuit board. Ive been going to check it. I have been too lazy though. Its like $30... When pulling a trailer the brake lights work on the trailer but still not on my truck.

 

Yea it's prob the circuit board that connects to the tail lights I also have a bad one on my k2500 which is causing the brake lights not to work.

 

Sounds like a good job for this weekend.... that and oil change and maybe a few beers.

 

+1 on the circuit board, had it go out on my 03. Up under the bed by the rear bumper. cheap and easy.
