Normal Operation
The passenger seat control switch is powered by battery voltage on circuit 1462 (RD/WH) and is supplied ground on circuit 1205 (BK). When pressed, the seat control switch supplies that voltage and ground to a power seat track motor to move the seat. When pressed in the opposite direction, the seat control switch reverses the polarity to that same power seat track motor, which moves the seat in the opposite direction. There is a power seat track motor that moves the seat horizontally (FORWARD/REVERSE) and a motor in the power recliner mechanism that moves the seat backrest forward or rearward.

Possible Causes
A power seat that does not move horizontally and/or vertically can be caused by:
- wiring, terminals or connectors.
- a faulty seat control switch.
- a faulty seat track motor (seat track).
