Power Seat Motor

This procedure covers the removal and replacement of a power seat motor on a 2015-2020 Ford F-150, including disconnecting the battery, removing the seat, and replacing the faulty motor assembly.

Warnings

Tools required

Parts

• Power seat motor assembly × 1 — Use OEM specification - specify track or recline motor as needed
• Seat motor mounting hardware kit × 1 — If original hardware is damaged

Preparation

1. Park vehicle on level ground and engage parking brake
2. Move the affected seat to the full rear position for easier access to front mounting bolts
3. Open driver door and ensure interior lighting is adequate or set up work light
4. Gather all tools and replacement parts before beginning work
5. Take photos of seat wiring harness connections and motor position for reference during reassembly

Procedure

1. 1

   Disconnect battery negative terminal
   Open the hood and locate the battery. Using a 10mm socket, loosen the negative battery terminal bolt and remove the cable from the battery post. Secure the cable away from the battery to prevent accidental reconnection. Wait at least 2 minutes for airbag system capacitors to discharge before proceeding.
   ⚠Always disconnect negative terminal first to prevent electrical shorts.

   Battery Terminal Bolts6 Nm (4 lb-ft)
2. 2

   Remove seat side trim panels
   Using a trim panel removal tool, carefully pry off the plastic side covers on both sides of the seat base. These covers conceal the seat mounting bolts. Start at the rear edge and work forward, releasing the retaining clips without breaking them. Set panels aside in a safe location.
3. 3

   Disconnect seat electrical connectors
   Locate all electrical connectors under the seat. There will be multiple connectors for the power seat motor, heated/cooled seat elements (if equipped), and occupancy sensor. Press the release tabs and carefully disconnect each connector. Note the position and routing of each connector for reassembly.
   ⚠Do not pull on wires; always pull on the connector body to avoid damaging wiring.
4. 4

   Remove seat mounting bolts
   Using a 13mm socket, remove the four seat mounting bolts that secure the seat tracks to the floor. There are two bolts at the front of each seat track and two at the rear. Keep these bolts organized as they will be reused. You may need to slide the seat forward and backward to access all mounting points.
   ⚠Have an assistant help support the seat weight before removing the final bolts.

5. 5

   Remove seat from vehicle
   With all mounting bolts removed and electrical connections disconnected, carefully lift the seat assembly straight up and out of the vehicle. Use proper lifting technique or get assistance due to the weight. Place the seat on a protected workbench or clean surface with the bottom facing up for motor access.
6. 6

   Locate and identify faulty power seat motor
   Inspect the underside of the seat to identify which motor has failed. Common motors include horizontal track motor (front/back movement), vertical lift motors (height adjustment), and recline motor (seatback angle). The motors are typically mounted with bolts or bracket assemblies. Compare with your reference photos to confirm motor orientation.
7. 7

   Disconnect motor electrical connector
   Locate the electrical connector attached to the faulty motor. Press the release tab and disconnect the connector from the motor. If the connector is secured with a small screw or clip, remove it first. Inspect the connector pins for corrosion or damage.
8. 8

   Remove motor mounting fasteners
   Using an 8mm or 10mm socket (depending on motor type), remove the bolts securing the motor to its bracket or the seat track mechanism. Most power seat motors are held by 2-4 bolts. Note any shims or spacers present and keep them with the hardware for reinstallation. If the motor is riveted, carefully drill out rivets and plan to use replacement bolts.
   ℹ️Some motors have plastic drive gears that may remain engaged in the seat mechanism. Gently rotate the motor to disengage if necessary.

9. 9

   Remove faulty motor from seat assembly
   Carefully extract the motor from its mounting position. If the motor drives a gear mechanism, ensure the drive gear disengages cleanly without forcing. Note the orientation of any drive cables or linkages that were connected to the motor. Inspect the drive mechanism for wear or damage while the motor is removed.
10. 10

    Install new power seat motor
    Position the new motor in the same orientation as the original, aligning any drive gears or cables with the seat mechanism. Ensure any spacers or shims are in their correct positions. Start all mounting bolts by hand before tightening to ensure proper alignment. Verify the motor gear engages smoothly with the drive mechanism.
    ⚠Incorrect motor orientation will prevent proper seat operation and may damage the drive mechanism.
11. 11

    Torque motor mounting bolts
    Using a torque wrench, tighten the motor mounting bolts to specification. Follow a cross-pattern if multiple bolts are present to ensure even pressure. Verify the motor is securely mounted and cannot rotate or shift in its bracket.

12. 12

    Reconnect motor electrical connector
    Plug the electrical connector into the new motor, ensuring it clicks fully into place. Verify the connector lock tab is engaged. If a retaining screw or clip was present, reinstall it to secure the connection. Gently tug the connector to confirm it is properly seated.
13. 13

    Reinstall seat in vehicle
    With assistance, carefully lift the seat assembly and position it over the four floor mounting points. Align the seat track mounting holes with the floor threaded inserts. Lower the seat into position, ensuring no wiring harnesses are pinched beneath the seat tracks.
    ⚠Route all wiring harnesses clear of seat tracks and moving mechanisms to prevent damage during seat operation.
14. 14

    Install and torque seat mounting bolts
    Install all four seat mounting bolts by hand, ensuring threads engage properly. Once all bolts are started, use a torque wrench with 13mm socket to tighten each bolt to specification in a cross-pattern (front left, rear right, front right, rear left) to ensure even seat mounting.

15. 15

    Reconnect seat electrical connectors
    Reconnect all electrical connectors under the seat, matching each connector to its correct mate based on your reference photos. Ensure each connector clicks into place and the locking tab engages. Route wiring to avoid interference with seat track movement.
16. 16

    Reinstall seat trim panels
    Reinstall the plastic side trim panels on both sides of the seat base. Align the retaining clips with their receptacles and press firmly until each clip snaps into place. Verify all panels are secure and properly seated.
17. 17

    Reconnect battery
    Return to the engine bay and reconnect the negative battery cable to the battery post. Ensure the cable terminal is clean and fully seated on the post. Tighten the terminal bolt to specification, being careful not to overtighten and damage the battery post.
    ⚠Do not overtighten battery terminal bolts as this can crack the battery post or strip threads.

Reassembly

1. Ensure all electrical connectors are fully seated and locked before operating the seat
2. Verify no tools or hardware have been left under or around the seat
3. Check that seat trim panels are fully clipped into place on both sides
4. Confirm wiring harnesses have adequate slack and are not routed through moving parts

Verification

• Turn ignition to ON position (engine does not need to run) and test all seat power functions: forward/backward, up/down (if equipped), recline, and lumbar (if equipped)
• Verify the repaired function operates smoothly without binding, unusual noise, or hesitation
• Test seat movement through full range of motion to ensure motor does not stall or struggle
• Check that airbag warning light is not illuminated on the instrument cluster, indicating proper seat sensor connections
• Operate seat several times to confirm reliable operation before returning vehicle to service
• Reset clock and radio presets as needed after battery disconnection
