Solution

1. Preparation

Gather tools: multimeter, socket set, screwdriver, wiring harness repair kit.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box and identify the fuse associated with the power seat.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if blown with a new fuse of the same amperage.

3. Test and Replace Power Seat Switch

Remove the power seat switch from the seat by unscrewing it or prying it out, depending on the model.
Inspect for visible damage and test with a multimeter for continuity.
If faulty, replace the switch with a new one.

4. Check and Replace Power Seat Motor

If the switch is functional, remove the seat from the vehicle for easier access to the motor.
Disconnect the wiring harness from the power seat motor and perform a direct power test.
If the motor does not operate when directly powered, replace the motor with a new one.

5. Inspect Wiring and Connections

Check the wiring harness for any frays, cuts, or corrosion.
Repair any damaged wires with a wiring harness repair kit or replace the entire harness if necessary.
Reconnect all wiring and ensure all connections are secure.
