Thanks guys. I didn't even think about the grounding. I'll bet it's that or a disconnected wire. Headlight switch must be good - it controls the park lights and interior lights and they all work fine. As a matter of fact, the old dimmer switch and headlight switch were probably ok too. Now I have a spare of each.
If it's not a grounding or cut/disconnected wire I'm burning the truck. Anybody want a 292?!?! :p :mad:
