Normal Operation

WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The seat control switch is powered by battery voltage on circuit 171 (BK/WH) and is grounded by circuit 57 (BK). When pressed in one of the 6 available directions, the seat control switch supplies voltage to the desired seat motor on the desired direction circuit. The seat control switch is normally closed to ground on all 6 of the seat motor circuits, so if one circuit becomes closed to power, the circuit on the opposite side of the same motor is still closed to ground. The seat motor will then operate, moving the seat track in the desired direction. Moving the seat control switch in the opposite direction reverses polarity to the seat motor, which causes the seat motor to move the seat track in the opposite direction. There are 3 seat motors integrated to the seat track assembly: 1 to move the seat horizontally (forward/rearward), 1 for front vertical (up/down) operation and 1 for rear vertical (up/down) operation.
