PINPOINT TEST C: THE POWER SEAT IS INOPERATIVE - PASSENGER, WITH POWER RECLINER

Normal Operation
The passenger seat control switch is powered by battery voltage to the passenger seat control switch, circuit 1462 (RD/WH), and is supplied ground on passenger circuit 1205 (BK). When pressed, the seat control switch supplies that voltage and ground to the power seat track motor or power recliner motor to move the seat or backrest. When pressed in the opposite direction, the seat control switch reverses the polarity to the power seat track motor or power recliner motor, which moves the seat or backrest in the opposite direction. There is one power seat track motor which moves the seat cushion horizontally (FORWARD/REARWARD) and an additional motor in the power recliner mechanism to move the seat backrest forward and rearward. If a new motor needs to be installed, it is necessary to install an entire power seat track or power recliner mechanism.

Possible Causes
An inoperative passenger power seat can be caused by:
- a fuse.
- wiring, terminals or connectors.
- a faulty seat control switch.
- a faulty power seat motor (power seat track).
