In my 91 bird, I believe the headlight switch is going out. The dimmer works but if you turn it sometimes the lights on the dash blink in and out, like a short or something. And if I try to turn just the parking lights on, the headlights come up but they are not on. From what I hear the parking lights are supposed to come on but the headlights should stay down. I was wondering how hard it is to change the headlight/dimmer switch. Thanks.

Not sure if this helps anything, but when I turn both on, then pull out my headlight switch they DO stay up. However, when I push ONLY the parking lamps while holding the headlight switch the headlights do stay down.
