Door Lock Actuator - Rear

This procedure covers removal and replacement of the rear door lock actuator on a 2015-2020 Ford F-150, including door panel removal and electrical disconnection.

Warnings

Tools required

Parts

• Rear door lock actuator × 1 — Use OEM Ford specification for specific door (driver/passenger rear)
• Door panel retaining clips (assorted) × 5 — Keep spares on hand, often break during removal

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect negative battery terminal to prevent electrical shorts and allow module to power down (wait 2 minutes after disconnect)
3. Open rear door fully and secure to prevent movement during repair
4. Gather all tools and new actuator before beginning work

Procedure

1. 1

   Remove door panel fasteners
   Remove the Phillips screw from the door pull handle cup. Remove the T20 Torx screw behind the interior door handle trim. Carefully pry off the small trim cover behind the door handle to access additional fasteners if equipped.
2. 2

   Disconnect door handle and switches
   Use a panel tool to carefully release the door handle bezel by pushing the clip tabs. Disconnect the electrical connectors for the power window switch and door lock switch by pressing the release tabs and pulling straight out. Remove the switch panel assembly from the door.
3. 3

   Remove door panel
   Starting at the bottom rear corner, use a panel removal tool to carefully pop the retaining clips around the perimeter of the door panel. Work your way around the entire panel, releasing approximately 8-12 clips. Once all clips are released, lift the panel upward to disengage it from the window ledge, then pull it away from the door frame.
   ⚠Apply steady, even pressure to avoid breaking clips or cracking the door panel.
4. 4

   Remove vapor barrier access
   Carefully peel back the plastic vapor barrier only in the area necessary to access the door lock actuator, typically near the door latch assembly in the rear edge of the door. Use care not to tear the barrier. The actuator is mounted to the door latch mechanism.
5. 5

   Disconnect actuator electrical connector
   Locate the door lock actuator mounted to the latch assembly. Press the locking tab on the electrical connector and pull straight out to disconnect. Note the connector orientation for reinstallation.
6. 6

   Disconnect actuator rod linkage
   Identify the plastic rod connecting the actuator to the door latch mechanism. Carefully unclip or slide the rod end off the actuator lever. Note the exact position and orientation of the rod connection for proper reassembly.
   ℹ️Take a photo of the linkage configuration before removal to ensure correct reassembly.
7. 7

   Remove actuator mounting fasteners
   Remove the three T30 Torx screws securing the door lock actuator to the door latch assembly. Support the actuator as you remove the final screw to prevent it from falling into the door cavity.
8. 8

   Remove old actuator
   Carefully maneuver the actuator out through the access opening in the door frame. You may need to rotate or angle the actuator to clear the door structure and other components. Remove it completely from the door.
9. 9

   Install new actuator
   Position the new actuator into the door cavity and maneuver it into place on the door latch assembly. Align the mounting holes with the latch mechanism. Insert the three T30 Torx mounting screws and tighten in a star pattern to secure the actuator evenly. Mounting Bolts torque specification is not specifically provided for door actuator screws; tighten securely by hand with Torx driver.
10. 10

    Reconnect linkage and electrical
    Reconnect the actuator rod linkage to the actuator lever, ensuring it snaps or clips securely into place in the same configuration as removed. Reconnect the electrical connector to the actuator until the locking tab clicks into place. Gently tug to verify secure connection.
11. 11

    Test actuator function
    Temporarily reconnect the negative battery terminal. Without reinstalling the door panel, use the key fob or interior lock switch to test the actuator function. Verify the actuator cycles properly through lock and unlock positions and the door latch operates correctly. Disconnect battery again before proceeding.
    ⚠Ensure all linkages move freely and the actuator operates smoothly before reassembly.

12. 12

    Reseal vapor barrier
    Carefully press the vapor barrier back into place, ensuring it adheres completely to the door frame with no gaps or wrinkles. This is critical for preventing water intrusion and wind noise.
13. 13

    Reinstall door panel
    Position the door panel over the window ledge and slide it down into place. Align all clip locations around the perimeter. Firmly press around the entire panel perimeter to seat all retaining clips. Reconnect the power window and lock switch electrical connectors and snap the switch panel back into the door panel. Reinstall the door handle bezel. Reinstall all screws in the door pull handle and behind the door handle trim.
14. 14

    Reconnect battery and finalize
    Reconnect the negative battery terminal and torque to specification. Test all door functions including lock, unlock, interior and exterior handles, power windows, and switches to verify proper operation.

Reassembly

1. Ensure all door panel clips are properly seated and the panel is secure with no rattles
2. Verify vapor barrier is completely sealed to prevent water and air leaks
3. Test power window auto up/down function and perform relearn procedure if necessary (hold up until fully closed, continue holding for 2 seconds; repeat for down)
4. Verify all electrical connectors are fully seated with locking tabs engaged

Verification

• Test door lock and unlock from key fob - should operate smoothly without binding
• Test door lock and unlock from interior switch - verify proper operation
• Test door lock and unlock from exterior key cylinder if equipped
• Verify interior and exterior door handles operate the latch correctly
• Check for proper door panel fit with no gaps or rattles
• Confirm power windows and all door switches function normally
• Test child safety lock function if equipped on rear doors
