Steps
Remove the rear door panel
Release the side push pins and remove the bottom screws. Open the handle and pull trim covers, remove their screws, lift the panel clear of the lock, and disconnect the latch rod and switch.
Secure the window and remove the regulator
Peel the water shield from its adhesive without tearing it, then lower the glass to reach its rail bolts. Raise and tape the glass securely, remove the door pull support and regulator fasteners, unplug the motor, and withdraw the regulator.
Install the replacement regulator
Feed the new regulator into the door and loosely hang it on its fasteners. Connect the motor, remove the tape, lower the glass onto its rail, and tighten the glass fasteners to the vehicle's specification.
Restore the water shield and support
Reinstall the door pull support and press the water shield adhesive back into place, securing it so water cannot reach the cabin. Reconnect the switch and latch rod, then align and clip the door panel into place.
Test the window
Reinstall the panel screws, covers, and push pins. Cycle the window through its full range and confirm the glass moves evenly without binding before closing the door.
Check your vehicle’s repair manual for exact specifications and fit.
