Replace a power window regulator on a 1999–2005 Pontiac Grand Am while keeping the glass supported and the water shield intact.

Steps

1. Remove the door panel

   Remove the door pull screws and trim, release the panel clips, and disconnect the switch and speaker wiring as equipped. Lift the panel away and peel back the water shield without damaging its adhesive edge.

2. Secure the glass and remove the regulator

   Raise the glass and tape it to the upper door frame. Unplug the window motor, remove the regulator fasteners and retaining plate, then guide the regulator assembly out through the door opening.

3. Install the replacement regulator

   Position the replacement regulator in the door and secure its track and brackets. Reconnect the motor, lower the glass onto its mounts, tighten the fasteners to the vehicle specification, and remove the support tape.

4. Test operation and reassemble

   Reconnect the switch temporarily and move the window through its range, checking for smooth travel without strain. Restore the water shield, reconnect the door wiring, and reinstall the panel, screws, and trim.

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