Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety throughout the repair process.
Tools Required: Socket set, multimeter, flathead screwdriver, Torx screwdriver.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Identify the power seat fuse (consult the owner's manual for the exact location).
Remove the fuse and inspect it for continuity. If blown, replace it with a new fuse of the same amperage.

3. Test and Replace Power Seat Switch

Remove the power seat switch panel using a flathead screwdriver or Torx screwdriver.
Disconnect the switch's wiring harness.
Use a multimeter to test for continuity across the switch terminals while pressing the seat adjustment buttons.
If the switch fails the continuity test, replace it with a new switch.

4. Check Wiring and Connections

Move the driver's seat to its furthest forward position manually if possible.
Inspect the wiring harness under the seat for any loose connections or visible damage.
If any wires are damaged, repair or replace them as necessary.

5. Inspect and Test Seat Motor

If the switch and wiring are functional, check the seat motor.
Disconnect the motor from the seat mechanism and apply direct power from the battery to test its operation.
If the motor does not function when powered directly, replace the seat motor.
