Normal Operation

WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

The power seat switch is powered by battery voltage on driver circuit 566 (DG) or passenger circuit 1462 (RD/WH) and is supplied ground on circuit 57 (BK). When pressed, the power seat 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 that same 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).
