I have a 1979 Firebird. Having trouble with the headlights, they don't work at all. Replaced the switch itself...nothing. The rear lights and the parking lights work flawlessly...just no headlights. Any help is greatly appreciated! Best answer will be awarded with points.

If the lamps are good, look for ground wires off at the body both sides.
If the running lights work it could be a bad switch although power comes to the switch from 2 sources.
The switch receives power from a body feed that could be out, while the running lights come from a fuse in the fuse box.

I use ot have that exact car and I had the exact same problem. The dealers and things apparntly get them in all the time. I am a 50 year old x machanic and I had them alot aswell. It is the electric system just before it gets to the light. What happens is, there is soo much current being sent and the lights cant take it, however they dont get all the power beacuse some of the wires just 'take the strain'. Anyway all in all it will cost around £100 max.

I assume you checked the bulbs, and they are good? If so, the problem is most likely in the high /low beam switch. If that goes bad, the headlights will not work.

I assume you've had a look at the fuse panel and all is fine there...Have you checked the headlight relay, under the hood, I believe nearby the battery. If you get voltage in, but none out-why, there's your problem!
Good Luck!
