Power Mirror Motor

This procedure covers the removal and replacement of the power mirror motor assembly on a 2015-2020 Ford F-150, requiring removal of the door trim panel to access the mirror mounting hardware.

Warnings

Tools required

Parts

• Power mirror motor assembly × 1 — Use OEM Ford specification
• Door panel clips (assorted) × 5 — Have extras on hand for any damaged during removal
• Mirror gasket/seal × 1 — Often included with mirror assembly

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition off and remove key
3. Disconnect negative battery terminal and wait 2 minutes for airbag system to discharge
4. Gather all replacement parts and verify correct mirror assembly for your specific trim level (heated, power-fold, camera, blind-spot, etc.)
5. Lower driver or passenger window completely to allow access if power is disconnected

Procedure

1. 1

   Remove door panel lower fasteners
   Using the T20 Torx bit, remove the two screws at the bottom of the door panel below the armrest. Remove the screw behind the door handle pull cup. If equipped, carefully pry out the small cover cap behind the interior door handle and remove the T30 Torx screw behind it.
2. 2

   Disconnect door control switches
   Carefully pry up the power window and lock switch assembly using a panel tool. Start at the rear edge and work forward. Once raised, disconnect the electrical connectors by pressing the release tabs and pulling straight up. Set the switch assembly aside.
3. 3

   Release door panel clips
   Starting at the bottom rear corner, use panel removal tools to gently pry the door panel away from the door frame. Work your way around the perimeter, releasing approximately 10-12 retaining clips. Apply steady outward pressure to avoid breaking clips. Once all clips are released, lift the panel straight up to disengage it from the window sill channel.
4. 4

   Disconnect door handle cable and harness
   Reach behind the door panel and disconnect any remaining electrical connectors. Unhook the door handle actuator cable by rotating the cable end 90 degrees and sliding it out of the handle lever. Carefully set the door panel aside on a protected surface.
5. 5

   Peel back water barrier
   Carefully peel back the plastic water barrier sheet enough to access the mirror mounting area at the top front corner of the door. The barrier is typically adhesive-backed. Work slowly to avoid tearing it, as it must be resealed during reassembly.
6. 6

   Disconnect mirror electrical connector
   Locate the mirror electrical connector inside the door cavity. Press the connector locking tab and pull the connector apart. If equipped with heated mirrors, power-fold, or additional features, there may be multiple connectors. Label them if necessary to ensure correct reinstallation.
7. 7

   Remove mirror mounting bolts
   From inside the door, locate the three mirror mounting bolts at the top front corner. These are typically 10mm fasteners accessed through the door frame opening. Remove all three bolts while supporting the mirror assembly from outside the vehicle to prevent it from falling.

8. 8

   Remove mirror assembly
   With all bolts removed, carefully guide the mirror assembly away from the door while feeding the wiring harness through the door opening. Note the position of any gaskets or seals for proper reinstallation. Inspect the mounting surface for damage or corrosion.
9. 9

   Install new mirror assembly
   Feed the new mirror assembly's wiring harness through the door opening. Position the mirror gasket correctly on the door frame. Align the mirror assembly with the three mounting holes and support it from outside while starting all three mounting bolts by hand. Ensure the mirror sits flush against the door.
10. 10

    Torque mirror mounting bolts
    Using a torque wrench, tighten the three mirror mounting bolts to 31.0 Nm (23 lb-ft) in a star pattern to ensure even pressure. Verify the mirror is secure and properly seated against the door frame with no gaps.

11. 11

    Reconnect electrical connectors
    Connect the mirror electrical connector(s) inside the door cavity. Ensure each connector clicks into place and is fully seated. Route the wiring harness so it does not interfere with the window regulator or door latch mechanisms.
12. 12

    Reseal water barrier and reinstall door panel
    Press the water barrier sheet back into place, ensuring complete adhesion around all edges to maintain moisture protection. Position the door panel at the top of the door frame and slide it down into the window sill channel. Reconnect the door handle cable and any electrical connectors. Press firmly around the perimeter to seat all retaining clips.
13. 13

    Reinstall door panel fasteners
    Reconnect the power window and lock switch assembly, ensuring all connectors click into place, then press the assembly down firmly. Install all door panel screws using the appropriate Torx bits. Replace any trim covers removed during disassembly.
14. 14

    Reconnect battery and test
    Reconnect the negative battery terminal and tighten to specification. Turn the ignition to the ON position (engine off) and test all mirror functions: power adjustment in all directions, heating function if equipped, power-folding if equipped, and blind-spot indicator if equipped. Verify smooth operation without binding or unusual noise.

Reassembly

1. Ensure all door panel clips are fully seated to prevent rattles
2. Verify the water barrier is completely sealed to prevent moisture intrusion into the door cavity
3. Test all door functions including interior handle, power locks, and window operation after reassembly
4. If power window auto-up/down function was lost, perform the relearn procedure: fully close the window, hold the switch up for 2 seconds, fully open the window, hold the switch down for 2 seconds

Verification

• Test mirror power adjustment in all directions (up, down, left, right) to verify full range of motion
• If equipped, verify heated mirror function operates correctly
• If equipped, test power-fold function in both directions
• Visually inspect mirror for proper alignment and secure mounting with no movement or vibration
• Check for any warning lights on the instrument cluster related to mirror functions
• Verify door panel is secure with no loose clips or rattles by gently pulling on various points
• Test drive vehicle and verify mirror remains stable at highway speeds with no excessive vibration
