Steps
Remove the door panel and shield
Pry off the pull and handle trim, remove their screws, and release the door-panel clips. Unplug the switch, lift the panel away, then peel back the water shield carefully.
Secure the glass and free the regulator
Raise the glass by hand and tape it securely to the door frame. Loosen its regulator fasteners, unplug the motor, remove the regulator and motor bolts, then guide the assembly out through the access opening.
Transfer the motor if needed
If the replacement regulator does not include a motor, transfer the original motor using the correct fasteners. Confirm the new assembly matches the old unit and its mounting points.
Install the regulator
Feed the assembly into the door, seat it on its mounts, and secure the fasteners. Reconnect the motor, lower the glass onto the regulator, and tighten its clamps evenly.
Test and reinstall trim
Remove the tape while supporting the glass and cycle the window through its travel. Check for binding, then restore the water shield, reconnect switches, and reinstall the door panel and trim.
Check your vehicle’s repair manual for exact specifications and fit.
