Normal Operation
The power seat switch is powered by battery voltage to driver seat control switch circuit 29-AH35 (OG/YE) and is supplied ground on driver circuit 91-AH35 (BN). When pressed, the power seat switch supplies the voltage and ground to the driver seat module (DSM). The DSM then supplies voltage and ground to the appropriate power seat track motor based on the inputs received from the seat control switch. When pressed in the opposite direction, the power seat switch reverses the polarity to the DSM, 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). The power recliner cannot be repaired separately. If the power recliner needs to be repaired, an entirely new front seat backrest frame must be installed.

Possible Causes
A memory seat that does not move horizontally/vertically can be caused by:
- a fuse.
- wiring, terminals or connectors.
- a faulty memory set switch.
- a faulty power seat track motor position sensor.
- a faulty DSM.
