Power Seat Operation

The seat front, rear vertical, and recline motors are reversible. For example, when the seat front vertical switch is pressed to move the front of the seat up, B+ is applied through the switch contacts and the seat vertical motor up control circuit to the motor. With the front vertical motor down switch contacts closed to the switch ground circuit, the motor runs in order to drive the front of the seat up until the switch is released. Moving the front of the seat down works similarly to moving the front of the seat up, except that battery voltage and ground are applied on opposite circuits causing the motor to run in the opposite direction. The seat rear vertical and recline motors are also powered this way.
