Solution

1. Preparation

Gather tools: multimeter, socket set, screwdriver set, and safety glasses.
Disconnect the vehicle battery to prevent electrical shock.

2. Fuse Replacement

Locate the fuse box (refer to the owner's manual).
Remove the fuse for the electric seat using a fuse puller.
Inspect the fuse for continuity; replace with a new fuse of the same amperage if blown.

3. Switch Replacement

Remove the seat switch panel using a flathead screwdriver.
Disconnect the electrical connector from the switch.
Test the switch with a multimeter for continuity when pressed; replace if faulty.

4. Wiring Inspection

Lift the seat and inspect the wiring harness for any visible damage or disconnections.
Repair or replace any damaged wiring found.

5. Motor Testing
