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 to move the seat. When pressed in the opposite direction, the seat control switch reverses the polarity to the power seat track motor, which moves the seat in the opposite direction. There is 1 power seat track motor which moves the seat horizontally (FORWARD/REARWARD). If a new motor needs to be installed, it is necessary to install an entire power seat track.

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).
