Having problems with your 2005 GMC Envoy ?
Lights---low beams are blowing out, and often I have no low beams, but can get the high beams. Fog lights work. Have had two new bulbs in four weeks.
You may have defective bulb sockets that may have overheated and are now deformed or corroded. Replacement socket pigtails are available at auto centers or parts store. Recommend getting ceramic sockets, these will not deform.
