Seats: Testing and Inspection

POWER SEATS
Before any testing of the power seat system is attempted, the battery should be fully-charged and all wire harness connections and pins cleaned and tightened to ensure proper continuity and grounds. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and joint connector location views for the various wire harness connectors, splices and grounds.
1. If all power seats are inoperative, check the automatic resetting circuit breaker in the Junction 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.
