This procedure covers the removal and replacement of the front power window motor on a 2021-2024 Ford F-150 with 3.5L EcoBoost engine.

Warnings

Tools required

Parts

• Front power window motor (driver or passenger side as needed) × 1 — Motorcraft WLM-series or Use OEM specification
• Door panel clips (replacement set) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Roll window to approximately mid-travel position before disconnecting battery
3. Disconnect negative battery terminal and wait 2 minutes for system capacitors to discharge
4. Gather all tools and replacement parts
5. Inspect new window motor to verify correct part before installation

Procedure

1. 1

   Remove door panel armrest and controls
   Remove the armrest pull cup using a trim tool. Remove the two T30 Torx screws behind the armrest. Disconnect the window switch electrical connector by pressing the release tab and pulling connector away. Remove the door handle trim bezel by carefully prying from the rear edge.
2. 2

   Remove door panel
   Remove all remaining door panel screws (typically 3-4 along bottom edge). Use trim panel removal tools to disengage the retaining clips around the perimeter of the door panel, working from bottom to top. Lift the panel upward to disengage from the door frame, then pull away from door. Disconnect any remaining electrical connectors for speakers or lighting. Set panel aside on protected surface.
3. 3

   Remove weathershield
   Carefully peel back the plastic weathershield (vapor barrier) from the door frame, starting at the bottom corner. Only remove enough to access the window motor and regulator mechanism. Use masking tape to temporarily secure the weathershield out of the work area. Avoid tearing the weathershield as it must be resealed.
4. 4

   Secure window glass
   With window in mid-travel position, use masking tape to secure the window glass to the door frame in the UP position. Apply tape from the top of the glass to the exterior door frame. This prevents the glass from dropping when the motor is disconnected. Alternatively, have an assistant hold the glass.
5. 5

   Disconnect window motor electrical connector
   Locate the window motor electrical connector. Press the locking tab and disconnect the connector from the motor. Move the wiring harness away from the work area to prevent damage.
6. 6

   Remove window motor mounting bolts
   Identify the window motor mounting bolts (typically three 10mm bolts). Remove all mounting bolts securing the motor to the regulator assembly and door frame. Keep bolts organized for reinstallation.

   Module Mounting Bolts8 Nm (6 lb-ft)
7. 7

   Separate motor from regulator
   Carefully maneuver the window motor away from the regulator mechanism. The motor drive gear may be engaged with the regulator gear - rotate slightly while pulling to disengage. Remove the motor through the access hole in the door frame. Note the orientation of the motor for proper installation of the replacement.
8. 8

   Install new window motor
   Position the new window motor in the same orientation as the original. Align the motor drive gear with the regulator gear mechanism. Carefully engage the gears while inserting the motor into the mounting position. Ensure the motor is fully seated against the mounting surface before installing bolts.

9. 9

   Secure motor and reconnect electrical
   Install all motor mounting bolts and torque to specification using a torque wrench. Reconnect the electrical connector to the motor, ensuring the locking tab clicks into place. Verify connector is fully seated.

10. 10

    Test window operation
    Remove tape securing the window glass. Reconnect the battery negative terminal and torque to specification. Test window operation using the door-mounted switch before reassembling the door panel. Window should move smoothly in both directions with no binding or unusual noise. Verify auto-up and auto-down functions if equipped.

    Battery Terminal Bolts6 Nm (4 lb-ft)
11. 11

    Reinstall weathershield and door panel
    Press the weathershield back into place, ensuring complete adhesion around all edges. Reconnect all electrical connectors to the door panel (speakers, switches, lighting). Position the door panel and engage the top edge onto the door frame. Press firmly around the perimeter to seat all retaining clips. Install all door panel screws and the armrest fasteners, ensuring proper torque on fasteners where specified.

Reassembly

1. Ensure all door panel clips are properly seated before forcing the panel into place
2. Verify the weathershield is completely sealed to prevent water intrusion into the door cavity
3. Test all door-mounted switches and controls for proper operation after panel reinstallation
4. Check that door handle operates smoothly and trim bezels are flush with panel surface

Verification

• Test window operation in both directions multiple times to verify smooth operation
• Verify auto-up and auto-down features function correctly (if equipped)
• Check for any unusual noises during window operation
• Confirm window travels full range from fully closed to fully open without binding
• Verify window seals properly at the top when fully closed
• Test window switch illumination and all other door panel functions
• Inspect door panel for proper fit and secure attachment with no rattles
