Seat Operation

WARNING: This page is about a different car, the 2003 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.

All seat motors are reversible. For example, when the seat switch is operated to move the entire seat forward, battery positive voltage is applied through the switch contacts and the seat horizontal motor forward control circuit, and ground is applied through the rearward switch contacts and the seat horizontal motor rearward control circuit. The motor then runs to move the entire seat forward until the switch is released. Moving the entire seat rearward works similarly to moving the entire seat forward, except that battery positive voltage and ground are applied on the opposite circuits causing the motor to run in the opposite direction. The seat front and rear vertical motors are also powered this way.
