Headlight Problems... any idea's??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Truck: 72 K-10. I went out to start my truck last night and the headlights refused to go on. All other lights work. I looked at the fuse panel and no blown fuses. The little 4 amp fuses on each side in the engine compartment above each lamp in the black w/ white stripes wires are fine. I'm not sure what else it could be??? Any anyone have any idea's???

Thanks

Check the ground on top of the core support on the passenger side. Unbolt it and scuff it. Also check the dimmer switch for corrosion on the floor.

I'll bet it's the dimmer switch wiring mine, was a little melted and corroded and gave me the same results.

I third the dimmer switch...they are notirous for going out and making your headlights now work. They only cost like $4 though
