This procedure covers replacement of the power mirror motor on a 2011-2014 Ford F-150 3.5L EcoBoost, including mirror trim removal, electrical disconnection, and motor replacement.

Warnings

Tools required

Parts

• Power mirror motor assembly × 1 — Use OEM Ford specification for specific mirror type
• Door panel clips (if damaged) × 1 — Ford door trim retainer set

Preparation

1. Park vehicle on level surface and engage parking brake
2. Lower driver or passenger window completely to prevent accidental power lock-in
3. Disconnect negative battery terminal and wait 2 minutes for airbag system to discharge
4. Identify which mirror (driver or passenger) requires motor replacement

Procedure

1. 1

   Remove mirror trim cover
   Starting at the rear edge of the mirror trim panel (triangular cover at door/mirror junction), insert trim removal tool between panel and door frame. Gently pry outward to release the retaining clips. Work around the perimeter until all clips are free. Carefully pull the trim panel away from the door.
2. 2

   Disconnect mirror electrical connector
   Locate the main mirror electrical connector behind the trim panel. Press the release tab on the connector and pull straight back to disconnect. If connector is difficult to access, you may need to partially lower the window regulator or reposition wiring harness. Note the routing of the wire harness for reinstallation.
   ⚠Do not pull on wires; always grasp the connector body to prevent wire damage
3. 3

   Remove mirror mounting bolts
   Using a 10mm socket, remove the three bolts securing the mirror assembly to the door. Support the mirror with one hand while removing the final bolt to prevent it from falling. Carefully pull the entire mirror assembly away from the door, feeding the wiring harness through the opening.
   ⚠Mirror assembly is heavier than it appears; maintain firm grip during removal

   Module Mounting Bolts8 Nm (6 lb-ft)
4. 4

   Remove mirror glass
   Place the mirror assembly face-down on a clean, padded work surface. Gently pull the mirror glass away from the housing. The glass is held by spring clips; pull firmly but steadily from one edge. Some models may have a small tab that needs to be pressed. Set the glass aside in a safe location to avoid scratching.
   ⚠Mirror glass can shatter if dropped; work over a padded surface and wear gloves
5. 5

   Access mirror motor assembly
   With the glass removed, locate the mirror motor assembly inside the housing. You will see the dual-axis motor assembly with gear mechanisms. Remove the T20 Torx screws securing the motor to the mirror housing (typically 2-3 screws). Note the orientation of the motor assembly before removal.
   ℹ️Take a photo of motor orientation and gear engagement before removal for easier reinstallation
6. 6

   Remove defective mirror motor
   Disconnect the internal electrical connector from the motor assembly. Carefully lift the motor out of the housing, noting how the drive gears engage with the adjustment mechanism. Check the condition of the plastic gears and ball-socket joints for wear or damage that may have caused motor failure.
7. 7

   Install new mirror motor
   Position the new mirror motor assembly in the housing, ensuring the drive gears properly engage with the adjustment mechanism ball joints. The motor should sit flush against the mounting surface. Connect the internal electrical connector, ensuring it clicks into place securely.
   ⚠Verify gear teeth are properly meshed before tightening screws to prevent binding or motor damage
8. 8

   Secure mirror motor
   Install the T20 Torx screws to secure the motor assembly to the mirror housing. Tighten screws in a cross-pattern to ensure even seating. Do not overtighten as the housing is plastic and can crack. Manually move the adjustment mechanism to verify smooth operation without binding.
9. 9

   Reinstall mirror glass
   Align the mirror glass with the adjustment ball joints protruding from the motor assembly. Press firmly and evenly around the edges of the glass until it clicks into the retaining clips. Ensure the glass is fully seated and does not rattle or sit unevenly.
10. 10

    Reinstall mirror assembly to door
    Feed the wiring harness through the door opening. Align the mirror base with the three mounting holes on the door. Install the three mounting bolts and tighten to specification in a star pattern to ensure even pressure distribution.

11. 11

    Connect electrical and test
    Reconnect the main mirror electrical connector, ensuring it clicks securely. Temporarily reconnect the negative battery terminal. Turn the ignition to the ON position (engine off) and test mirror operation using the door-mounted mirror adjustment switch. Verify up, down, left, and right movement in both directions. If equipped, test power-fold and heating functions.
12. 12

    Reinstall trim panel
    Once mirror operation is verified, disconnect the battery again. Position the mirror trim panel and align all retaining clips with their corresponding holes in the door frame. Press firmly around the perimeter until all clips snap into place. The panel should sit flush with no gaps.

Reassembly

1. Reconnect negative battery terminal and torque to specification
2. Reset power windows by lowering each window fully, then raising fully and holding switch for 2 seconds
3. Verify all mirror functions including adjustment, folding (if equipped), and heating (if equipped)
4. Check that mirror trim panel is secure and properly aligned with door contours

Verification

• Test mirror adjustment in all four directions using the door-mounted control switch
• Verify smooth, quiet operation with no grinding or clicking noises
• Check that mirror holds position and does not drift after adjustment
• If equipped, verify power-fold function operates smoothly in both directions
• If equipped, verify heated mirror function by checking for condensation clearing
• Ensure no rattles or loose components when closing door firmly
