This procedure covers the removal and replacement of the rear window motor and regulator assembly on a 2015-2020 Ford F-150, including door panel removal and electrical disconnection.

Warnings

Tools required

Parts

• Rear window regulator and motor assembly × 1 — Use OEM specification
• Door panel retaining clips (if broken) × 1 — Use OEM specification

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. Roll rear window down approximately halfway if motor is still functional; if not, you will need to manually support the glass
4. Gather all tools and replacement parts before beginning

Procedure

1. 1

   Remove door panel lower fasteners
   Using the T30 Torx driver, remove the two Torx screws at the bottom edge of the rear door panel. Remove the screw located in the door pull handle recess. Carefully pry out the power window switch assembly using a panel tool, then disconnect the electrical connector.
2. 2

   Remove door panel
   Starting at the bottom rear corner, use panel removal tools to carefully release the retaining clips around the perimeter of the door panel. Work your way around the panel, releasing each clip. Lift the panel upward to disengage it from the upper door frame, then pull away from the door. Disconnect any remaining electrical connectors for speakers or courtesy lights.
3. 3

   Remove moisture barrier access
   Peel back the plastic moisture barrier enough to access the window regulator and motor assembly. You do not need to completely remove it. Use masking tape to hold it back if necessary. Identify the window regulator mounting bolts and motor electrical connector.
4. 4

   Secure window glass
   If the window is in the down position, carefully raise it to near the top of the door frame. Use masking tape to secure the glass to the door frame to prevent it from falling when the regulator is disconnected. Ensure the glass is stable and will not shift during regulator removal.
5. 5

   Disconnect window motor electrical connector
   Locate the window motor electrical connector inside the door. Press the locking tab and carefully disconnect the connector from the motor. Move the wiring harness out of the way to provide working clearance.
6. 6

   Remove window glass from regulator
   Locate the two 10mm bolts that attach the window glass to the regulator lift bracket. These are typically accessible through access holes in the inner door structure. Remove both bolts while continuing to support the glass with tape. Carefully lift the glass completely up and secure it in the full-up position with additional tape.
7. 7

   Remove regulator mounting bolts
   Using a 10mm socket, remove all regulator mounting bolts. There are typically three to four bolts securing the regulator assembly to the inner door panel. Keep track of bolt locations as some may be different lengths. Support the regulator assembly as you remove the final bolt.

8. 8

   Remove regulator and motor assembly
   Carefully maneuver the regulator and motor assembly out through the large access opening in the inner door structure. You may need to rotate and angle the assembly to clear the door frame. The motor is typically attached to the regulator and removed as a complete unit.
9. 9

   Install new regulator and motor assembly
   Guide the new regulator and motor assembly into the door through the access opening. Position it so the mounting holes align with the threaded inserts in the door frame. Install all mounting bolts hand-tight first, then torque to specification using a torque wrench.

    Reconnect window glass to regulator
    Remove the tape securing the window glass. Lower the glass carefully until the holes in the glass mounting bracket align with the regulator lift bracket. Install the two 10mm bolts and torque to specification. Verify the glass is securely attached before proceeding.

    Reconnect electrical and test
    Connect the window motor electrical connector, ensuring it clicks into place securely. Reconnect the negative battery terminal and torque to specification. Before reinstalling the door panel, test the window operation through its full range of travel multiple times. Verify smooth operation with no binding or unusual noises.

    Reinstall moisture barrier and door panel
    Reposition the plastic moisture barrier and press it firmly to ensure a good seal. Reconnect all electrical connectors to the door panel components. Align the door panel with the upper door frame and slide it down into position. Press firmly around the perimeter to engage all retaining clips. Reinstall all Torx screws removed earlier.

Reassembly

1. Ensure all door panel clips are fully seated and the panel is secure with no gaps
2. Verify all electrical connectors are properly engaged and locked
3. Test window operation from both door switch and driver's master switch

Verification

• Operate the window through full up and down cycles at least three times to verify smooth operation
• Listen for any unusual noises, grinding, or binding during window movement
• Verify the window seals properly at the top of the door frame when fully closed
• Check that the window auto-up and auto-down features work correctly (if equipped)
• Perform window re-initialization procedure if required: with ignition on, hold window switch down until window is fully down, continue holding for 2 seconds, then pull switch up until window is fully up and hold for 2 seconds
• Confirm door panel is secure with no rattles or loose clips
