Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, multimeter, flathead screwdriver, pliers.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the cover and find the fuse for the power seat (refer to the owner's manual for exact location).
Inspect the fuse; if blown, replace it with one of the same amperage.

3. Inspect and Repair Wiring

Reconnect the negative battery terminal.
Remove the seat from its mounting (usually secured by bolts).
- Sub-steps:
  - Slide the seat forward and locate the rear mounting bolts.
  - Use a socket wrench to remove the bolts and slide the seat backward to access front bolts.
  - Remove the front bolts and carefully lift the seat out.
Inspect the wiring harness connected to the seat for any signs of wear, fraying, or disconnection.
Repair or replace damaged wiring as necessary.

4. Replace Seat Adjustment Motor

If the wiring is intact, the motor may be faulty.
Disconnect the seat adjustment motor from the wiring harness.
Remove any retaining screws or bolts holding the motor in place.
Replace with a new motor and secure it properly.
Reconnect the wiring harness.

5. Reinstall Seat

Position the seat back into the vehicle.
Align the seat with the mounting holes and install the front and rear bolts.
Torque the bolts to the manufacturer's specifications (usually around 30-35 Nm).
