How to Replace the Power Window Switch on a 2008 GMC Envoy
- 1). Slide the flat-head screwdriver between the oval panel and the plastic door panel and pry upward on the screwdriver. The oval panel attaches to the door panel with one tab on each end. Prying upward on the oval panel forces the tabs to break loose.
- 2). Pull the oval panel out of the door panel and turn it over.
- 3). Remove each wiring harness from the oval panel. The harnesses push onto a metal tab on the switch. To remove, pull them off with your fingers. Make sure you mark each wire and denote which metal tab the wire goes. This ensures you connect each harness to the correct switch.
- 4). Plug each of the wiring harnesses into the new oval control panel.
- 5). Turn on the Envoy and test each switch to ensure you reconnected the harnesses correctly. Turn the GMC off once finished.
- 6). Place the oval panel onto the door panel with the harness inside the door panel. Push the panel down to snap it into place.
