Headlight switch headlights will not come on all other lights work

I guess you are saying that after you turned the ignition off, the headlights and all lights went off, but when you returned and turned ignition on all lights but the headlights came on. "a gremlin" stole my light switch? Possible, but most likely your headlight switch is bad, or the headlight relay, or if the dimmer switch makes no difference, It could be power supply or connection to the headlight dimmer relay is bad. Corrosion causes funny behavior. Clean bright metal connections make a world of difference. Follow headlight wiring back to a small box usually on the inside fender of the Engine bay. Check all connections including the ground to the frame (body metal).

These are all different circuits. The brake lights are on a 10amp fuse - the headlights are on a 50amp fuse - and the parking and dash lights are on a 20amp fuse.
Do you have power going into the headlight switch and the brake light switch ?

HEADLIGHTS NOT WORKING

It can be issue with headlight switch,but as its already been replaced.Try disconnecting high beam headlight wiring from headlight assembly and reconnect direct external wire from headlight switch to headlight assembly,then by switch see if headlight is getting off and turning on or not.

No. Dash lights being out could be a bad headlight switch, since the dash lights are routed through the headlight switch, not the dimmer switch. Park and tail lights also controlled by the headlight switch.

how do you replace a headlight switch in a 07 grand prix gtp. head lights do not come on. all other lights work. fuses are good. amd so are the bulbs. was told that the headlights themselves were not getting a charge. and was told that it was the headlight switch.

The relay has nothing to do with the tail lights, but replacing the switch sounds like a good idea. There's a nut holding it in place, see http://www.skandix.de/en/spare-parts/electrics/switches/switch-headlight/1027524/ to get an idea of the construction. And the price. This is not worth fiddling about unreliable workarounds...
In addition, if fuses 15 and/or 16 burn frequently there might be a problem with the tail light cabling.

Good luck
Ingo

check the headlight switch for burned contacts or a heat dis-colored connector to it. If u find either replace the headlight switch and the connector as a pair.

There is a circuit breaker inside the headlight switch body. It gets weak over time and use. The breaker is actually mentioned in the owners manual. A new switch is about $75.00 at the local parts store. You must remove the front of the dash to change the switch. Mine would go off and then in about 30 seconds reset and the lights would come back on. I would be driving down the road with my headlights flashing as the circuit breaker opened and closed. New switch = problem fixed.
