Seats: Testing and Inspection

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.

With the dome lamp on, apply the power seat switch in the direction of the failure. If the dome lamp dims, the seat may be jamming. Check under the seat for binding or obstructions. If the dome lamp does not dim, proceed with testing of the individual components and circuits.

Circuit Breaker
1. Locate the correct circuit breaker in the fuse- block module. Pull out the circuit breaker slightly, but be sure that the terminals still contact the terminals in the fuseblock module cavities.
2. Connect the negative lead of a 12-volt DC voltmeter to a good ground.
3. With the voltmeter positive lead, check both terminals of the circuit breaker for battery voltage.

If only one terminal has battery voltage, the circuit breaker is faulty and must be replaced. If neither terminal has battery voltage, repair the open circuit from the Power Distribution Center (PDC) as required.
