I have searched the forums with no luck. I have a 1999 GMC Yukon that is the same as the 1999 Tahoe is that correct? My low beams do not work, My high beams work as well as the DRL work. I believe the DRL's are the same bulb as the low beams just lower voltage. I replaced the switch on the dash. I checked the fuses inside vehicle and under the hood and all are good. There are no relays for low beam. I looked at the low beam bulbs and they look intact. Can anyone give me a idea on a fix? Do I need a new dimmer switch I hope not becase that switch is $200.00 and unless I know it is bad I don't have money to rule that out

Thanks Bob
