Two problems related to power window have been reported for the 2005 GMC Envoy. The most recently reported issues are listed below.
Both of my windows which slide down with the push of a button do not work! they have both busted. One is stuck down. The other I have to shove up because while driving from the vibrations it falls. Very unsafe. They both stopped work while I was operating them by pushing the button for them to slide down. I have not replaced them yet. Its very costly. Its hard to believe no recall has been done. I have found many other complaints regarding this.
2005 GMC Envoy has developed multiple problems. The driver side front seat side cover was coming off and the passenger side front window was inoperative. Both issues were recurrent.
