Normal Operation
WARNING: This page is about a different car, the 2008 Mercury Sable, 2008 Ford Taurus X, and 2008 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
The passenger seat control switch is powered by battery voltage to the passenger seat control switch, circuit SBB21 (GY/RD), and is supplied ground on passenger circuit GD148 (GK/YE). When pressed, the seat control switch supplies that voltage and ground to the power seat track motor to move the seat. When pressed in the opposite direction, the seat control switch reverses the polarity to the power seat track motor, which moves the seat in the opposite direction. There is one power seat track motor which moves the seat horizontally (forward/rearward). If a new motor needs to be installed, it is necessary to install an entire power seat track.
This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Seat control switch
- Power seat motor (seat track)
