Ok so I have a 96 2 door 5.7 l Chevy Tahoe and my headlights are out. The wires that power the bulbs are receiving no power. The switch is good all relays and fuses are good so are the bulbs. The only thing I haven't changed is the DRL module because the day time lights are still working just fine. So does it have anything to do with the headlights? should I change it out? Or could of be something else like the multi function switch? All my other lights work just not headlights hi or low. The light on the dash doesn't even come on. Some One had said the ground from the computer could be the problem but I'm not getting any power to even test that. Please give me any ideas u may have cuz they have been out for months and I don't have the $500 the shop wants to fix it. Thanks : )
