1995 GMC Sonoma Lighting Electrical

Could be headlamp switch or dimmer switch or wiring. Note the wire colors in diagram, check for voltage. The diagram is for composite lamps.

As you can see, the headlamp switch sends voltage to dimmer switch on yellow wire. You can see wire colors for high and low beam.

Any work on steering column and you need to disarm air-bag, where applicable.

Hey thank you! I appreciate the help. Where are these switches located? When this happened I heard some ticking from the glove box, I found some relays there I replaced the one that seemed to operate the lights and the problem still exists.

Your headlamp switch should look like the picture. Your dimmer switch should be part of multifunction switch on the steering column.
