Newbie here. Been over at Corral with my stangs for years. My 2004 Silverado is all of a sudden having no brake lights. I'm worried about some clown rear ending me in traffic and need to get this fixed ASAP. I've owned the truck since new. It has had a small camper shell on it for the past 8 years.

It's a 2004, 4X4, Club cab. I have looked at the fuses and they seem to be fine.

I don't have a wiring diagram for this vehicle. I'm assuming that the circuit is the same for brake light that comes on at the top of the cab as the rear brake lights but not sure?

I have had duck hunting gear in and out of the shell and traveled with it some this year. I'm wondering if the wiring for the shell may have gotten disturbed and caused the brake lights in the bed not to work? The turn signals and the running lights in the bed work fine.

Anyone have a wiring diagram or some advice that might help me? Thanks!

 

You do not say, but did you check the bulbs? It is common for the bulbs and sockets to get corrosion on them making a bad connection. A good cleaning of both will usually fix the problem. Have done anything to the truck that might have disturbed the wiring?

 

I have not done any mods to the truck other than the shell which was added about 8 years ago. It looks like there is a relay of some sort near the back left hand side of the shell. If the bulbs/sockets were corroded would both go out at the same time?

Like I said I have had lots of duck hunting gear in and out of it along with dog crates and other stuff, but that is it.

Also, the turn signal lights work fine on both sides. Are these the same as the brake lights or different? I have never cracked the cases open on these lights.
