    My "04" 2500hd Is not supplying power to the left brake light. Truck has towing package. I checked the fuse for the trailer left stop/turn (ok) then I checked for power to the fuse and there was none. Right side is fine. Anyone have any Ideas?

    solved

    Stopped by the dealer today, and was able to talk to the shop forman. problem was a relay mounted on the back of the fuse box. It was a real p.i.t.a. to replace but it solved the problem!
