Would appreciate any help with this! My 2001 GMC Jimmy (4X4) low beam headlights won't come on! I always have the headlights set to automatically come on when I start the car. I know cannot get the low beams to come on at all! I've had the headlamps checked and they are fine, also the fuses seem to be ok. I can't drive at night like this using my high beams and blinding people. PLEASE HELP!
