Steps
Remove the door panel and water shield
Switch off the ignition. Release the handle bezel and courtesy light, unplug the light, and remove the panel screw. Free the panel clips and lift the panel away, unplug the window switch, then peel back the water shield and remove the foam access block carefully.
Remove the lock assembly
Remove the interior-handle bolt and release the lock rods from their clips. Remove the latch assembly's Torx fasteners, disconnect its wiring plugs, and withdraw the lock assembly from the door while noting each rod's route.
Replace the actuator on the lock assembly
Remove the two T10 screws securing the actuator and separate it from the lock assembly. Seat the replacement actuator in the same orientation and reinstall its screws, ensuring the drive and lock rod engage correctly.
Reinstall the lock assembly
Reconnect the lock wiring and position the assembly in the door. Reinstall its Torx fasteners, reconnect the rods to their correct clips, and secure the interior handle. Operate the lock before closing the door to confirm full movement.
Restore the water shield and door panel
Return the foam block and water shield to their original positions. Reconnect the window switch and courtesy light, align the panel, and press its clips home. Reinstall the screws and handle bezel, then test the power lock and manual lock before closing the door.
