Difficulty: Advanced · About 70 min · Ford Explorer

Replace the driver's door lock actuator on a 2002–2010 Ford Explorer by removing the door trim and lock hardware, transferring connections, and testing the locks before reassembly.

Steps

1. Remove the driver's door panel

   Turn off the ignition. Release the trim around the switch panel and handle, remove the panel's 7 mm fasteners, and unplug the window and mirror switches. Lift the panel upward, release the lock cable, and set it aside without pulling its wiring.

2. Free the lock cylinder

   Remove the small retaining bolt and slide its guard forward. Release the latch rod clip, remove the lock-cylinder retaining nut, and withdraw the cylinder while keeping the rods and clips oriented for reassembly.

3. Remove the failed actuator

   Remove the two bolts securing the window track and move the track clear. Remove the actuator's Torx fasteners, release the lock rod and electrical plugs, then maneuver the actuator out through the door opening.

4. Fit the replacement actuator

   Position the replacement actuator in the lock mechanism and reconnect its sensor leads and harness. Seat the actuator fully, start its Torx fasteners by hand, and tighten them evenly before returning the window track and its bolts.

5. Reinstall the lock cylinder and door trim

   Reconnect the lock cylinder to its rod, seat it in the door, and refit its retaining nut, guard, and clips. Reconnect the door-panel cable and switch wiring, hang the panel on the door, press in its clips, and reinstall its fasteners and trim.

6. Test the repair

   Before closing the door, operate the interior handle and power locks several times with the door open. Confirm the lock knob and key cylinder move freely, then check the window and mirror controls and verify the panel is secure.
