Steps
Remove the door panel and water shield
Switch off the ignition. Release the handle trim and panel clips, remove the screws, and disconnect the door switches, courtesy light, and control module wiring. Separate the weather shield carefully with a utility knife, keeping the blade away from wires and the door paint.
Raise and secure the window
Reconnect the switch and door-control module temporarily, turn the ignition to accessory, and raise the glass until its rail bolts are accessible. Switch the ignition off, disconnect the switch, remove the rail bolts, lift the glass by hand, and secure it to the door frame with painter's tape.
Remove the regulator and door brace
Remove or loosen the door-brace fasteners and move the brace clear. Remove the regulator mounting bolts and speaker, disconnect the motor harness, and slide the regulator off its keyways and out through the door opening.
Install the replacement regulator
Feed the new regulator into the door and reconnect its motor harness. Seat it on the keyways and install its mounting bolts, then return the door brace and secure its fasteners. Reinstall the speaker and reconnect its wiring.
Reattach the glass and test
Support the glass while removing the tape and lowering it onto the regulator rail. Install and tighten both glass bolts, reconnect the switch, and cycle the window to confirm smooth travel. Switch the ignition off before disconnecting the switch and reassembling trim.
Restore the water shield and door panel
Reconnect the module, courtesy light, mirror, lock, and window wiring, then clip the harnesses into their retainers. Return the weather shield, hang the door panel, and reinstall its clips, screws, and trim. Verify all door controls before closing it.
