This procedure covers the removal and replacement of the rear window motor and regulator assembly on a 2021-2024 Ford F-150 SuperCrew or SuperCab with power windows.

Warnings

Tools required

Parts

• Rear window regulator and motor assembly × 1 — Use OEM specification
• Door panel retaining clips (if damaged) × 10 — Ford push-pin retainers
• Vapor barrier adhesive (if damaged) × 1 — 3M 08008 or equivalent

Preparation

1. Park vehicle on level surface and engage parking brake
2. Roll rear window to fully up position before beginning work
3. Disconnect negative battery terminal and wait 2 minutes for system discharge
4. Gather all tools and new parts before starting disassembly
5. Clean exterior door area to prevent dirt entry during panel removal

Procedure

1. 1

   Remove door panel
   Remove the screw cover from the door pull handle. Remove the T30 Torx screw behind the cover. Carefully pry out the switch bezel using a panel tool and disconnect the window and lock switch connectors. Remove any additional T30 screws around the door panel perimeter (typically 2-3 screws). Starting at the bottom rear corner, use panel tools to release the retaining clips around the door panel perimeter. Lift the panel up and away from the door frame.
2. 2

   Remove watershield access
   Carefully peel back the vapor barrier enough to access the regulator mounting bolts and motor connector. Use painter's tape to secure the barrier out of the way. On some models, there may be a plastic service panel that can be removed instead of peeling the entire barrier. Keep the barrier intact for reuse if possible.
3. 3

   Disconnect window motor
   Locate the window motor electrical connector inside the door cavity. Press the release tab and disconnect the connector from the motor. Secure the connector to prevent it from falling into the door cavity.
4. 4

   Support and secure window glass
   Have an assistant support the window glass from the outside, or secure it in the full-up position using painter's tape from the glass to the door frame exterior. This prevents the glass from dropping when disconnected from the regulator. Ensure the glass is stable before proceeding.
5. 5

   Disconnect glass from regulator
   Locate the two 10mm bolts that attach the window glass channel to the regulator lift arms (accessible through access holes in the door inner panel). Loosen these bolts and carefully slide the glass upward to separate it from the regulator arms. Verify the glass is securely taped in the up position.
6. 6

   Remove regulator mounting bolts
   Locate and remove the regulator mounting bolts (typically three 10mm bolts) that secure the regulator assembly to the door inner panel. Note the position of any spacers or brackets attached to these bolts for proper reinstallation.
   Torque spec

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

   Remove regulator and motor assembly
   Carefully maneuver the regulator and motor assembly out through the largest access opening in the door inner panel. This may require tilting and rotating the assembly. The regulator arms must be carefully guided through the door structure. Take care not to damage the vapor barrier or interior door components.
8. 8

   Install new regulator assembly
   Guide the new regulator and motor assembly into the door cavity through the access opening. Position the regulator mounting holes to align with the door panel mounting points. Ensure the regulator arms are properly oriented and the motor is accessible for electrical connection.
9. 9

   Install regulator mounting bolts
   Install the three regulator mounting bolts with any spacers or brackets in their original positions. Tighten bolts in a cross pattern to ensure even seating. Torque mounting bolts to specification.

   Module Mounting Bolts8 Nm (6 lb-ft)
10. 10

    Connect glass to regulator
    Remove the tape securing the window glass. Lower the glass carefully until the regulator lift arms align with the glass channel mounting points. Install the two 10mm bolts through the glass channel into the regulator arms and tighten securely but do not overtighten to avoid cracking the glass channel.
11. 11

    Connect motor and test operation
    Connect the electrical connector to the window motor. Reconnect the negative battery terminal temporarily. Test window operation through several full up and down cycles to verify smooth operation and proper alignment. Disconnect battery again before proceeding.
    Torque spec

    Battery Terminal Bolts6 Nm (4 lb-ft)
12. 12

    Reinstall watershield and door panel
    Carefully reposition the vapor barrier, ensuring complete adhesion around all edges. If adhesive is compromised, apply new vapor barrier adhesive. Replace any damaged retaining clips on the door panel. Reconnect the window and lock switch connectors. Position the door panel and press firmly around the perimeter to seat all clips. Install all T30 Torx screws and replace the screw cover.

Reassembly

1. Ensure all electrical connectors are fully seated with audible clicks
2. Verify vapor barrier is completely sealed to prevent water intrusion and wind noise
3. Check that all door panel clips are fully engaged before testing
4. Reconnect battery and torque terminal bolt to specification

Verification

• Reconnect battery negative terminal and torque to 6.0 Nm (4.0 lb-ft)
• Perform window initialization: hold switch up for 2 seconds after window closes fully, then hold down for 2 seconds after window opens fully
• Test window operation through 5-10 complete cycles, verifying smooth operation with no binding or unusual noise
• Verify window seals properly against weatherstripping when fully closed
• Check that window auto-up and auto-down features work correctly (if equipped)
• Inspect door panel for proper fitment with no gaps or rattles
• Test all switches in the door panel to confirm proper reinstallation
