I had a right side fog light out, and rather than have the dealer take care of it ,I went exploring I pulled the lower cover,( behind the fog light) off and started tracing the loom. Single line, I had to pull the liner behind the tire and reach in to trace the loom , running my fingers along the wiring I found somthing that didn't feel right , and it was a broken connection/wire. It was a SOB to install an in-line splice,due to my bad back and the just out of reach location, but I did it and not the dealer Back to the thread ,yes the fog light wiring diagram is missing!!!!
