Normal Operation
The seat control switch is powered by battery voltage on circuit 566 (DG) 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 power seat switch reverses the polarity to the power seat track motor, which moves the seat in the opposite direction. There are 3 power seat track motors that combine to move the seat horizontally (FORWARD/REVERSE) and vertically (front UP/DOWN and rear UP/DOWN).

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.
