Power Seats System Description and Operation

The drivers power seat system consists of the following components:

Seat vertical motor

Vertical

When the seat switch is operated to lift the seat cushion up, battery positive voltage is applied through the switch contacts and the vertical motor up control circuit to the vertical motor. The motor is grounded through the down switch contacts and the vertical motor down control circuit to the motor. The motor runs in order to drive the seat cushion up until the switch is released. Lowering the seat cushion works similarly to lifting the seat cushion, except that battery positive voltage and ground are applied on opposite circuits causing the motor to run in the opposite direction.
