I am having a problems with my right tail light. When I use the blinker with the headlights off, it will work. However, when I turn the headlights on, the it will act like I have the hazards on and the reverse lights also will flash. It is only a problem with the right tail light. When I use the left side, it works like it should. Any ideas? thanks

 

if i remember right on the older trucks ALL electronics gong to the rear, goes throu the turn signal plate under the steering wheel. but dont know about the newer trucks. if i remember right.

 

Reverse lights don't.....

Got a trailer harness? Try disconnecting that first......

 

trailer harness was the culprit for me. ended up being too much resistance in the wires. spliced in some new wires, and its as good as new!
