I have a 2005 Avalanche that I use to pull my boat and small trailer. The problem is that the left brake light and turn signal on the either trailer does not work. I have checked all wiring and traced it back to the wiring harness on my truck.
The right side works just fine. I know that the left side is a yellow wire that runs from the rear of the truck to the front but I haven't traced it all the way up. I checked all the fuses and the 7 pin hookup and it is ok. Any suggestions before I have to go to a dealer for help?
