My headlight switch on my 1992 Firebird works fine when I turn on the headlights. Everything comes on. However when I turn on just the parking lights, my headlights flip up but the lights stay off. Why is the headlight motor recieving a signal to actuate? Is this possibly a bad switch? I have replaced a few bad bulbs recently (I've owned the car for three weeks) and I know years ago 1994-ish I had some crazy electrical issues arise from installing a wrong tail light. But to the best of my knowledge all the lights that I have changed have been correct. I have changed a fog light, a shifter light and a drivers side tail light.

Any info would be helpful

 

 

Thank you so much! I suspected the switch. I really appreciate the response.

 

I also have this problem intermittently, so I'd be curious to the results of replacing the switch. When I had mine apart to clean I didn't really see how it could contact the other one early, but you never know.

 

I would imagine the switch could go bad. It is responsible for doing a lot. It turns on the parking lights, fog lights and interior lights with the one section, and the headlights and the headlight motor with the second part. I know several wires work go into a plug that goes into the back. I'm sure corrosion anywhere would cause a short. I just didn't want to change the switch for no good reason.
