Where can I get a diagram of the fuse panel? My brake lights, tail lights and reverse lights are all out.

 

If the horn works I suspect the NSS on the transmission is really dirty causing the B/U lights not to work........common problem

 

Awesome! Thanks man.

 

If the fuses are good check the ground. I replaced my ground cable this weekend with one that had a little pig tail on it with a spade. I bolted it to a near by bolt. The lights are brighter and the turn singals are stronger and everthing electrical runs the same at idle or at speed. Don't underestimate the ground.

 

when you say ground cable, are you referring to the negative battery cable? Just want to clarify because I saw the tailights have ground wires coming off of the back of the bulb fixture. The wires were in good shape and had a solid ground.

 

What is an NSS? Where about would it be located on a C6?

 

NSS = Neurral Start (safety) Switch.

It is located on the side of the transmission.

 

What would you recommend to clean it with? I've got some carb and brake cleaner in the toolbox...
