Component Tests and General Diagnostics

DIAGNOSIS AND TESTING

Before any testing of the Power Seat System is performed, the battery should be fully charged. All the wiring harness connectors should be inspected and cleaned, if necessary, to ensure good connections.

1. If all of the power seat functions are inoperative, check Fuse 22 for the driver seat, and Fuse 21 for the passenger seat in the Underhood Accessory Fuse Block.

2. With the dome lamp on, apply the power seat switch in the direction of the failure.

3. If the dome lamp dims, the seat or the power seat track may be jammed. Check under and behind the seat for binding or obstructions.

4. If the dome lamp does not dim, proceed with testing of the individual power seat system components and circuits.
