Power Seat Motor

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

Warnings

Tools required

Parts

• Power seat motor assembly × 1 — Use OEM specification for specific seat track position

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. Move the affected seat to a position that provides best access to the motor location (typically mid-travel)
4. Remove any floor mats or debris from around the seat base

Procedure

1. 1

   Remove seat lower trim panel
   Using trim panel removal tools, carefully pry off the plastic trim panel covering the seat base. Start at the rear corners and work forward. Disconnect any electrical connectors for seat heating or climate control if equipped.
2. 2

   Locate and identify the failed motor
   Inspect the underside of the seat to identify which motor has failed. The fore/aft motor mounts to the seat track, the recline motor mounts to the seat back hinge, and the height adjustment motors mount to the lift mechanism on each side. Verify motor position matches the failed function.
3. 3

   Disconnect motor electrical connector
   Locate the electrical connector on the failed motor. Press the release tab and disconnect the wiring harness connector from the motor. On some motors, you may need to release a secondary locking tab first.
4. 4

   Remove motor cable connection
   If the motor uses a flexible drive cable (common on height adjustment motors), carefully disconnect the cable from the motor output shaft. Note the orientation and routing of the cable for reassembly. Some cables simply pull off while others require a retaining clip to be released.
5. 5

   Remove motor mounting bolts
   Using a 10mm socket, remove the bolts securing the motor to the seat frame or track mechanism. Most motors are secured with 2-3 bolts. Support the motor while removing the final bolt to prevent it from falling.

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

   Extract the motor assembly
   Carefully maneuver the motor out of its mounting position. You may need to rotate or angle the motor to clear surrounding components. Be mindful of sharp edges on the seat frame.
7. 7

   Compare old and new motors
   Before installation, verify the replacement motor matches the original in terms of mounting holes, connector type, and output shaft orientation. Check that any included hardware or brackets are correct.
8. 8

   Install new motor assembly
   Position the new motor into the mounting location, ensuring any locating pins or alignment features are properly seated. Thread in the mounting bolts by hand initially to prevent cross-threading.
9. 9

   Torque motor mounting bolts
   Using a torque wrench, tighten the motor mounting bolts to 31.0 Nm (23.0 lb-ft) in a cross pattern if multiple bolts are present. Ensure the motor is properly seated against its mounting surface before final torque.

10. 10

    Reconnect drive cable
    If applicable, reconnect the flexible drive cable to the motor output shaft, ensuring it is fully seated and oriented correctly. Install any retaining clips if present. Verify the cable moves smoothly without binding.
11. 11

    Reconnect electrical connector
    Connect the wiring harness to the motor, ensuring the connector locks securely. You should hear or feel a positive click when properly seated. Verify any secondary locking tabs are engaged.
12. 12

    Reconnect battery and test motor function
    Reconnect the negative battery terminal and torque to specification. Before reinstalling trim panels, test the motor operation through its full range of motion. Verify smooth operation without binding, grinding, or unusual noises.
    Torque spec

    Battery Terminal Bolts6 Nm (4 lb-ft)
13. 13

    Reinstall seat trim panel
    Reconnect any electrical connectors for seat heating or climate control. Align the trim panel with its mounting clips and press firmly until all clips engage. Verify the panel is secure and flush along all edges.

Reassembly

1. Ensure all electrical connectors are fully seated and locked
2. Verify seat trim panels are properly clipped and seated before use
3. Test all seat functions including fore/aft, recline, and height adjustment to ensure proper operation

Verification

• Operate the seat through its full range of motion in all directions to confirm proper motor function
• Listen for any unusual noises during operation that might indicate binding or improper installation
• Verify the seat moves smoothly and stops at the correct positions without hesitation
• Check that all trim panels are secure and no rattles are present
• Confirm no warning lights are present on the instrument cluster related to the seat or airbag systems
