1995 Chevy Astro Headlights

I'd have to check voltage circuits to and from the headlamp switch. There is no fuse for the headlamp section, there is a circuit breaker in the headlamp switch, also a fusible link on the circuit that carries voltage to the switch. Red wire should be feed for headlamp, then, yellow wire carries headlamp feed to dimmer switch. From dimmer switch to headlamps. Without checking the wiring circuits, can't be sure where the problem is located.

WOW! Thank You very much. This is an awesome website
