Electrical problem
2001 GMC Sierra V8 Four Wheel Drive Automatic 150000 miles
----------------------------------------------------------------
Headlights will not come on. All others including high beam working. Cheacked all fuses and relays that I know of - Electrical box under hood and drivers side panel. When lights are turned on no voltage to either headlight socket. Tried with automatic sensor on and disabled.

OK, Tried headlight switch(good), replaced headlight switch anyway-no dice. I am at a complete loss with this problem. A guy told me he thought it might be the dimmer switch, but with the brights working is that possible? Again checked voltage to low beams-nothing(high beams fine). Only thing I know to do is start unwrapping wires and see what I can see.
If you think of anything, please let me know
Thanks
