Parts
- Heated seat module × 1 — Use OEM Ford part matching vehicle seat configuration
- Electrical contact cleaner × 1 — Non-residue type
Preparation
- Park vehicle on level surface and engage parking brake
- Turn ignition off and remove key
- Disconnect negative battery terminal and wait at least 2 minutes for airbag system to discharge
- Move the affected seat fully forward to access rear mounting bolts
- Gather all tools and parts before beginning
Procedure
- 1Remove Seat Mounting BoltsLocate the four seat mounting bolts that secure the seat track to the floor. Remove the rear two bolts first using a 10mm socket. Then slide the seat fully rearward and remove the front two mounting bolts. The heated seat module is typically located under the driver or passenger seat.Torque specModule Mounting Bolts8 Nm (6 lb-ft)
- 2Tilt Seat BackwardCarefully tilt the seat backward to gain access to the underside. You may need an assistant to help hold the seat in position. Be careful not to strain any wiring harnesses still connected to the seat.⚠Seat is heavy; use proper lifting technique or get assistance to avoid injury
- 3Locate Heated Seat ModuleThe heated seat module is mounted to the underside of the seat frame, typically near the center or toward the front of the seat. It will have multiple electrical connectors attached. Use a flashlight to inspect the location and connector positions. Take photos for reference during reassembly.
- 4Disconnect Electrical ConnectorsDisconnect all electrical connectors from the heated seat module. Press the locking tabs and pull connectors straight out. There are typically 2-4 connectors depending on seat configuration (heated elements, occupancy sensor, etc.). Inspect connectors for corrosion or damage.
- 5Remove Module Mounting HardwareRemove the bolts or screws securing the heated seat module to the seat frame. These are typically small Torx or hex head fasteners. Keep track of all hardware for reinstallation.Torque specModule Mounting Bolts8 Nm (6 lb-ft)
- 6Remove Old ModuleCarefully remove the heated seat module from its mounting location. Note the orientation and any wire routing clips that may need to be reused. Inspect the mounting area for any damage or corrosion.
- 7Clean Mounting Surface and Ground PointsClean the mounting surface where the module attaches using a wire brush if necessary. Ensure any ground connection points are clean and free of corrosion. This is critical for proper module operation.ℹ️Poor ground connections are a common cause of heated seat failures
- 8Install New Heated Seat ModulePosition the new heated seat module in the same orientation as the original. Align mounting holes and ensure any wire routing clips are properly positioned. Install mounting hardware finger-tight initially.Torque specModule Mounting Bolts8 Nm (6 lb-ft)
- 9Reconnect Electrical ConnectorsReconnect all electrical connectors to the new module, ensuring each connector clicks firmly into place. Verify connector orientation matches your reference photos. Gently tug each connector to confirm it is locked.
- 10Return Seat to Upright PositionCarefully return the seat to its upright position, ensuring no wiring is pinched or strained. Route any wiring through existing clips and channels.
- 11Reinstall Seat Mounting BoltsSlide the seat fully forward and install the rear mounting bolts first. Then slide the seat fully rearward and install the front mounting bolts. Torque all four mounting bolts to specification in a diagonal pattern.⚠Ensure seat tracks are aligned properly with floor mounting points before tightening boltsTorque specModule Mounting Bolts8 Nm (6 lb-ft)
- 12Reconnect BatteryReconnect the negative battery terminal. Torque the battery terminal bolt to specification. Do not overtighten as this can damage the terminal.Torque specBattery Terminal Bolts6 Nm (4 lb-ft)
Reassembly
- Ensure all electrical connectors are fully seated and locked
- Verify no wiring is pinched between seat and floor
- Confirm seat slides freely on tracks after reinstallation
- Double-check all mounting bolts are torqued to specification
Verification
- Turn ignition to ON position (engine does not need to run)
- Test heated seat operation by pressing the heated seat button and verifying the indicator light illuminates
- Allow 2-3 minutes for seat to begin warming; verify heat is felt in seat cushion and backrest if equipped
- Test all heat settings (low, medium, high) if vehicle is equipped with multiple settings
- Verify no warning lights appear on instrument cluster
- Slide seat forward and backward through full range of motion to ensure proper operation
- Test seat adjustment controls to verify no interference with new module
