Auto Parts: 1990 GMC Headlight issue, dimmer switch, headlights

Question
Both of my headlights quit working simultaneously. The parking lights are still on. I couldn't figure out where the fuse is since I figured this was the problem.

Answer
Hi Erik,

Chances are that the dimmer switch is the culprit as you have the classic symptoms of a dead dimmer switch.

Headlights use relays and breakers, not fuses.

Thanks for the question, I hope this information was helpful to you.
