1. Check Power Source
- Turn on the ignition.
- Check for power at the seat motor by connecting a multimeter to the motor connections.
- If there's no power, check the fuses and wiring harness for issues.
2. Check Seat Motor
- Disconnect the seat motor.
- Apply 12 volts directly to the motor terminals to see if it runs.
- Replace the motor if it doesn't work.
3. Check Seat Switch
- Remove the seat switch panel and check for loose connections or damaged wiring.
- Test the switch by pressing it and checking for power output with a multimeter.
- Replace the switch if necessary.
4. Check Seat Track
- Confirm the seat track is clear and not obstructed, affecting seat movement.
- Clean or lubricate the tracks as needed.
5. Check Seat Control Module
- If other issues, consider checking the seat control module (SCM).
- It may need reprogramming or replacement.
Remember that these steps are a general guide, and the specific issue with your seat may differ. It's always a good idea to consult with a qualified mechanic or refer to the vehicle service manual for your exact model and year.
