Does anyone know what runs the third brake light on the top of the back window of an iroc, i dont see any connections to it, it worked when i got it but all the sudden quite, i pulled it of and all the bulbs are still good, if anyone has any ideas please let me know. Thanks alot Aaron

 

Well the 3rd on my Camaro isnt at the top of the rear shield its on the spoiler but I'm wondering the same thing...

 

The way the Genral did these car was kinda wierd, but here goes. This is from a 96 Impala, but it should be close as the General likes to do things the same as much as possible.

The stop/hazard fuse feeds a switch on the brake pedal. When the brake pedal is depressed the switch closes throught to two outputs. One feeds the regular brake lights, the other feeds the high mounted/center lamp, the ABS module, cruise control module, and remote door lock receiver.
This is probably why they interact when one thing goes in trouble.

 

So is it a fuse problem, cause ive checked the fuses to and i dont find any bad ones.

 

Well i figured out the problem, the idiots that tinted my windows cut and removed the wire that runs in with the rear defrost witch also powers the 3rd brake light, and didnt even tell me, go figure, so now im gonna have to pull the light off and wire a ground and a power in with my brakes, so this should be fun.

 

I knew if you got pissed enough, you would find the problem.

 

Yeah i know, everyone was always like, hey did you know your third isnt working, so now i know what the prob is, i wont have to listen to them anymore asking me about it.
