2002 gmc envoy headlights wont come on,checked fuses and bulbs what else could it b?
checked bulbs an fuses
Welcome to JustAnswer, my name is XXXXX XXXXX X'X here to help get your problem resolved. This is a common problem caused by the headlamp drive module which looks like a relay in fusebox under hood. It is #46 in picture, swap it with #45 to see if they come on. If so replace, its about a $7 part at parts store. here is a diagram of fusebox. Let me know if you have any questions, thanks.http://db.tt/GG6QyTWd
