Tools required

Parts

• Power mirror motor assembly × 1 — Use OEM specification for specific mirror type
• Door panel retaining clips (if broken) × 5 — Ford push-pin retainers

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect negative battery terminal and wait 2 minutes for airbag system to discharge
3. Lower driver or passenger side window completely to access upper door panel fasteners
4. Protect door sill with towel or cloth to prevent scratches during door panel removal

Procedure

1. 1

   Disconnect battery
   Using a 10mm socket, loosen and remove the negative battery terminal bolt. Move the cable away from the battery post and secure it so it cannot make contact. Wait 2 minutes before proceeding.

2. 2

   Remove door panel screws
   Remove the T20 Torx screw behind the door handle pull cup. Remove the Phillips screw in the lower front corner of the door panel near the mirror triangle cover. If equipped with manual window controls, carefully pry off the window crank handle retaining clip.
3. 3

   Remove mirror triangle trim cover
   Carefully insert a trim panel tool between the mirror triangle cover and the door frame at the front edge. Gently pry the cover away from the door, working around the perimeter to release the retaining clips. Pull the cover forward and away from the door. The mirror will remain attached to the door at this point.
4. 4

   Disconnect mirror electrical connector
   Locate the mirror electrical connector behind the triangle cover area. Press the connector locking tab and pull the connector straight out from the mirror base. If connector is difficult to access, you may need to partially lift the door panel in the next step first.
5. 5

   Release door panel clips
   Starting at the bottom rear corner, carefully insert trim panel tools between the door panel and door frame to release the push-pin retaining clips. Work your way around the perimeter, releasing approximately 8-10 clips. Lift the panel upward to disengage the upper retention hooks, then pull the panel away from the door. Set the panel aside on a protected surface.
6. 6

   Remove mirror mounting bolts
   Through the access hole in the door frame, locate the three 10mm bolts securing the mirror assembly to the door. Support the mirror from the outside with one hand while removing the bolts with the other. Remove all three bolts completely.
   ⚠Support the mirror from outside while removing the last bolt to prevent it from falling and causing damage or injury

7. 7

   Remove mirror assembly
   With all three bolts removed and the electrical connector disconnected, carefully pull the mirror assembly away from the door. Guide the wiring harness through the door opening as you remove the mirror. Inspect the door mounting surface for damage or corrosion.
8. 8

   Install new mirror assembly
   Feed the electrical connector of the new mirror through the door opening. Align the mirror mounting studs with the holes in the door frame. From inside the door, start all three mounting bolts by hand to ensure proper thread engagement. Support the mirror from outside to maintain alignment.
9. 9

   Torque mirror mounting bolts
   Using a torque wrench and 10mm socket, tighten the three mirror mounting bolts in a star pattern to ensure even pressure. Torque each bolt to 42.0 Nm (31 lb-ft). Verify the mirror sits flush against the door frame with no gaps.

    Reconnect electrical connector
    Connect the mirror electrical connector by pushing it firmly into the mirror base until you hear and feel the locking tab click into place. Gently tug on the connector to verify it is fully seated.
11. 11

    Reinstall mirror triangle cover
    Position the mirror triangle cover over the mirror base, aligning the retaining clips with their receptacles in the door frame. Press firmly around the perimeter until all clips snap into place. Ensure the cover sits flush with no gaps.
12. 12

    Reinstall door panel
    If any retaining clips were broken during removal, install new clips into the door panel. Position the door panel below the window opening, then lift it up to engage the upper retention hooks. Press firmly around the perimeter of the panel to seat all push-pin clips. Reinstall the Phillips screw in the lower front corner and the T20 Torx screw behind the door handle.
13. 13

    Reconnect battery
    Reconnect the negative battery terminal and tighten the terminal bolt to 6.0 Nm (4.0 lb-ft). Do not overtighten as this can damage the battery terminal.

Reassembly

1. Verify all door panel clips are fully seated and the panel is secure with no rattles
2. Check that all screws have been reinstalled in the door panel
3. Recalibrate power window auto-up/down if necessary by holding window switch up for 3 seconds after window is fully closed

Verification

• Turn ignition to ON position without starting engine
• Test all mirror functions: up, down, left, right movement using mirror control switch
• If equipped, verify heated mirror function operates correctly
• If equipped, verify power-folding mirror function operates smoothly
• Check that mirror holds position firmly without drooping or vibration
• Verify no rattles or abnormal noises from door panel when closing door firmly
