Ground to what GJ! in the dimmer switch it self, or the temp gauge? They both work.

It could be any multitude of places. As these trucks age contact points between body panels get corroded and lose continuity, ground points themselves do the same. It's time to find and clean to bare metal every ground point on the truck. If that doesn't fix it then running new ground wires from body panels to the frame or directly to the battery is the next step.


Thanks guys! I guess I have some investigation to do. dakota
