Normal Operation
WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
The driver seat control switch is powered by battery voltage to the driver seat control switch, circuit 566 (DG), and is supplied ground on driver 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 are 3 power seat track motors that combine to move the seat cushion horizontally (FORWARD/REARWARD) and vertically (front UP/DOWN and rear UP/DOWN). If a new motor needs to be installed, it is necessary to install an entire power seat track.
