This procedure covers removal and replacement of the heated seat module, which controls the heating elements in the front seats of the 2015-2020 Ford F-150.

Warnings

Tools required

Parts

• Heated seat module × 1 — Use OEM specification
• Plastic trim clips (if damaged) × 1 — Ford trim clip assortment

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition off and remove key
3. Disconnect negative battery terminal and wait 2 minutes for airbag system to deplete
4. Move seat fully forward to access rear mounting bolts
5. Ensure seat heater switches are in OFF position

Procedure

1. 1

   Disconnect Battery
   Loosen and remove the negative battery terminal using a 10mm socket. Move the cable away from the battery post to prevent accidental reconnection. Wait at least 2 minutes before proceeding to allow supplemental restraint system capacitors to discharge.
   Torque spec

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

   Remove Seat Mounting Bolts
   Locate the four seat mounting bolts (two at front, two at rear). Use an 8mm or 10mm socket depending on model year to remove all four bolts. Some models may use Torx bolts. Keep bolts organized for reinstallation.
   Torque spec

   Module Mounting Bolts8 Nm (6 lb-ft)
3. 3

   Tilt Seat Back
   Carefully tilt the seat backward to access the electrical connectors underneath. You may need an assistant to hold the seat or use a support to prevent it from falling. Be careful not to strain the electrical connectors still attached.
   ⚠Seat is heavy - get assistance if needed to prevent back injury or damage to connectors
4. 4

   Disconnect Seat Electrical Connectors
   Locate all electrical connectors under the seat including the heated seat harness, power seat motors (if equipped), and seat position sensors. Press the release tabs and carefully disconnect each connector. Note the routing and position of each connector for reassembly.
   ⚠Locking tabs are fragile - use proper release technique by pressing tab while pulling connector
5. 5

   Remove Seat from Vehicle
   With all connectors disconnected, carefully lift the seat assembly out of the vehicle. Place the seat on a clean, protected work surface with cushion facing up. This provides better access to the underside components.
   ⚠Seat weighs approximately 50-70 lbs - use proper lifting technique
6. 6

   Access Heated Seat Module
   Turn the seat upside down or on its side. Locate the heated seat module, which is typically mounted to the seat frame with plastic clips or bolts. The module is a small rectangular box connected to the seat heater element wiring. Remove any protective covers or shields if present.
   Torque spec

   Cover Screws14 Nm (10 lb-ft)
7. 7

   Disconnect Module Connectors
   Identify the electrical connectors attached to the heated seat module. There will typically be a power/ground connector and connectors to the heating elements in the seat cushion and backrest. Press the locking tabs and carefully disconnect all connectors from the module.
   ℹ️Take photos before disconnecting to ensure correct reconnection of multiple similar-looking connectors
8. 8

   Remove Module Mounting Hardware
   Remove the bolts or screws securing the heated seat module to the seat frame using the appropriate socket. Most modules use 10mm bolts or T20 Torx screws. Keep all hardware for reinstallation.
   Torque spec

   Module Mounting Bolts8 Nm (6 lb-ft)
9. 9

   Remove Old Module
   Once all mounting hardware is removed, carefully remove the heated seat module from the seat frame. Inspect the mounting location for any corrosion or damage. Clean the mounting surface if necessary.
10. 10

    Install New Module
    Position the new heated seat module in the same orientation as the original. Align the mounting holes with the seat frame. Install the mounting bolts and tighten to specification using a torque wrench.
    Torque spec

    Module Mounting Bolts8 Nm (6 lb-ft)
11. 11

    Reconnect Module Connectors
    Reconnect all electrical connectors to the new heated seat module, ensuring each connector clicks into place securely. Apply a small amount of dielectric grease to connector seals if desired for corrosion protection. Verify all connectors are fully seated.
12. 12

    Reinstall Seat in Vehicle
    Carefully lift the seat assembly and position it back in the vehicle, aligning the mounting holes with the floor brackets. Do not fully tighten mounting bolts yet to allow for connector routing.
13. 13

    Reconnect Seat Electrical Connectors
    Reconnect all electrical connectors under the seat in reverse order of removal. Ensure proper routing of wiring harnesses to prevent pinching. Verify all connectors click into place and locking tabs are engaged.
14. 14

    Secure Seat Mounting Bolts
    Install all four seat mounting bolts and tighten to specification using a torque wrench. Ensure the seat sits flush on all mounting points before final tightening. Verify the seat moves smoothly on its tracks without binding.

15. 15

    Reconnect Battery
    Reconnect the negative battery terminal and tighten the terminal bolt to specification. Do not overtighten as this can damage the terminal or battery post.
    ⚠Ensure terminal is clean and free of corrosion before reconnection

    Battery Terminal Bolts6 Nm (4 lb-ft)

Reassembly

1. Ensure all electrical connectors are properly seated and locked
2. Verify seat mounting bolts are torqued to specification and seat is secure
3. Check that no wiring is pinched or rubbing on sharp edges
4. Reset clock and radio presets after battery reconnection

Verification

• Turn ignition to ON position without starting engine
• Test heated seat function by pressing the heated seat switch and verifying the indicator light illuminates
• Allow seat heater to run for 2-3 minutes and feel for warmth in both seat cushion and backrest
• Verify no warning lights are illuminated on the instrument cluster
• Test seat movement in all directions if power seats are equipped
• Ensure seat mounting is secure with no movement or rattles
