I am sorry your having this problem

when this is acting up if you wiggle the headlight switch at all will any of the headlights come on for a second ?

Customer: replied 1 year ago.
Headlights not working at all now. Had to drive a while to a safe spot with the lights going on and off. Switch heated up. Now 1/2 hour later, no lights at all. I wiggled the switch, no effect. When I turn headlight switch to on all other lights dim. I'm at 6000 ft in the Ruby Mountains , Elko NV beautiful and cold. Thanks Dave

Dave the odds are with that switch getting hot the electrical connector into the back that is plugged into that switch usually has a bad terminal connection which will over heat and sometimes melt the connector at the back of the head light switch

the odds are having the switch removed and that connector and terminal inspected next will usually show the headlight switch overheated which replacing the headlight switch and the terminals melted or even the connector replaced is melted enough

but that's what has to be done next especially when the switch physically will be hot
