Driver and Passenger Power Seat Operation

The seat adjuster motors are controlled by relays through the adjuster motor supply circuits. The adjuster motor relays are controlled by the seat adjuster switches. The relay coils are supplied fused battery positive voltage from the instrument panel electrical center. The relay coils use separate ground circuits or control circuits connected to the seat adjuster switch. When an adjuster switch is pressed the relay coil control circuit is closed to ground and the relay is energized. There is one relay for each supply circuit which provides power or ground used for adjuster motor operation. When the relays are de-energized the supply circuits are closed to ground. When one adjuster motor relay is energized voltage is supplied to the adjuster motor and ground is provided through the de-energized relay. The direction of the adjuster motor rotation is determined by which of the adjuster motor relays are energized and de-energized.
