Normal Operation
The driver seat control switch is powered by battery voltage on circuit 517 (BK/WH) and is supplied ground on circuit 57 (BK). When pressed, the seat control switch supplies that voltage and ground to the appropriate power seat track motor or recliner motor to move the seat or backrest. When pressed in the opposite direction, the seat control switch reverses the polarity to that same power seat track motor, which moves the seat or backrest 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 driver 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 power recliner assembly.
- a faulty seat track motor.
