Tools required

Parts

• Rear door lock actuator assembly × 1 — Use OEM specification
• Door panel retaining clips (assorted) × 1 — Replacement for broken clips

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect 12V battery negative terminal and wait 2 minutes for system discharge
3. Open the rear door fully and secure it in open position
4. Roll window completely up before starting door panel removal
5. Prepare a clean padded surface to place removed door panel

Procedure

1. 1

   Remove door panel fasteners
   Use Torx T20 driver to remove the screw inside the door pull handle pocket. Remove the screw from behind the interior door handle trim. Carefully pry out the small trim cover behind the door handle using a trim tool, then remove the Torx T30 screw underneath. Remove any additional screws along the bottom edge of the door panel.
2. 2

   Disconnect door handle mechanism
   Carefully pull the interior door handle trim away from the panel. Disconnect the door release cable by lifting it out of the handle mechanism. Release any electrical connectors for window switches or power locks at the door handle assembly. Set the handle trim aside.
3. 3

   Remove door panel
   Using door panel removal tools, carefully disengage the retaining clips around the perimeter of the door panel by pulling straight out. Start at the bottom corners and work upward. Once all clips are released, lift the entire panel upward to clear the top retaining lip, then pull away from door. Disconnect any remaining electrical connectors from the back of the panel including courtesy lights.
4. 4

   Remove water barrier access
   Carefully peel back the plastic water barrier sheet just enough to access the door lock actuator area near the door latch assembly. Use care not to tear the barrier. You may need to cut or carefully peel back adhesive to create a working access window.
5. 5

   Disconnect actuator electrical connector
   Locate the door lock actuator near the rear edge of the door, integrated with the door latch assembly. Press the locking tab and disconnect the electrical connector from the actuator. Note the connector orientation and routing for reinstallation.
6. 6

   Disconnect actuator linkage rods
   Identify the plastic linkage rods connecting the actuator to the door latch mechanism. Using a flathead screwdriver or pick tool, carefully pop the rod ends off their ball studs on the actuator. There are typically 2-3 rods connected. Take a photo for reference before disconnecting.
7. 7

   Remove actuator mounting fasteners
   Remove the Torx T30 screws securing the door lock actuator to the door frame or latch assembly. There are typically 3 mounting screws. Support the actuator as you remove the final screw to prevent it from falling inside the door cavity.
8. 8

   Remove old actuator
   Carefully maneuver the old actuator out through the access hole in the door frame. You may need to rotate or angle it to clear surrounding components. Inspect the mounting area and clean any debris or corrosion from mounting surfaces.
9. 9

   Install new actuator
   Position the new door lock actuator in the mounting location, ensuring it is properly oriented with linkage rod connection points accessible. Align the mounting holes with the door frame. Install the mounting screws and tighten in a cross pattern to secure evenly. Verify actuator sits flush against mounting surface.
10. 10

    Reconnect linkage rods
    Snap each linkage rod back onto its corresponding ball stud on the new actuator. Ensure each connection is fully seated and secure. Gently tug on each rod to verify positive engagement. Compare to reference photos taken during disassembly.
11. 11

    Reconnect electrical connector
    Plug the electrical connector back into the new actuator until the locking tab clicks into place. Ensure connector is fully seated and routing matches original path to avoid pinching during door panel reinstallation.
12. 12

    Test actuator operation
    Reconnect the 12V battery temporarily. Using the key fob or interior lock switch, test the door lock and unlock functions multiple times. Verify smooth operation with no binding or unusual noise. Check that both lock and unlock cycles complete fully. Disconnect battery again before proceeding.
13. 13

    Restore water barrier
    Press the plastic water barrier sheet back into place, ensuring all adhesive areas are properly sealed. If adhesive has lost effectiveness, apply new weatherstrip adhesive to maintain a proper moisture seal. Ensure no gaps remain around the work area.
14. 14

    Reinstall door panel
    Reconnect all electrical connectors to the back of the door panel. Position the panel and engage the top edge under the window sill lip first. Push the panel firmly into place around all edges to engage the retaining clips. Replace any broken clips with new ones. Reinstall all screws in reverse order of removal.

Reassembly

1. Ensure all door panel screws are tightened securely but do not overtighten to avoid cracking plastic
2. Verify all trim pieces and covers are properly seated and secured
3. Reconnect the 12V battery negative terminal
4. Check that door panel is flush and all gaps are even around the perimeter

Verification

• Test door lock and unlock functions from both interior switch and key fob multiple times
• Verify door opens and closes normally from both interior and exterior handles
• Listen for smooth actuator operation without grinding, clicking, or binding noises
• Confirm all door panel features work correctly including window switches and courtesy lights
• Check that door seals properly when closed and no wind noise is present during test drive
