Replace the power door-lock switch on a 2000–2005 Pontiac Sunfire by removing the door panel and transferring the switch into its bezel.

Steps

1. Remove the door panel

   Switch off the ignition and remove the screws from the triangular trim, door pull, and lower panel. Release the manual window-crank clip with the proper tool and pull off the crank.

2. Disconnect the panel

   Lift the panel away from the door and unplug the lock-switch harness. Release the panel retainers without pulling on the wiring.

3. Replace the lock switch

   Remove the harness retainer from the panel and release the switch from its bezel. Press the replacement into the bezel until its tabs engage, then secure the harness.

4. Reinstall the panel

   Reconnect the lock-switch plug and align the panel with the door. Press its clips in, reinstall the screws, and refit the window crank and trim.

5. Test the lock switch

   Turn on the vehicle electrical system and test both lock and unlock commands. Confirm the manual window crank and door panel are secure.

Check your vehicle’s repair manual for exact specifications and fit.
