WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
The seat control switch is powered by battery voltage to circuit 517 (BK/WH) and is supplied ground on circuit 57 (BK). When either FORWARD or REARWARD recliner positions are selected on the seat control switch, power and ground is applied to circuits 918 (GY) and 919 (GY/BK) powering the recliner motor to move the seat UP or DOWN. When the opposite switch position is selected, the seat control switch reverses the voltage polarity to the recliner motor to move the seat in the opposite direction.
