The driver and passenger power seat systems each consist of the following components:

The driver and passenger power seat systems operate independently of each other. Each motor contains an electronic circuit breaker (PTC) that will reset only after voltage has been removed from the motor. Battery positive voltage (B+) is supplied at all times to each seat switch from the PWR SEAT Circuit Breaker located in the rear fuse block.

When the seat switch is operated to move the entire seat forward, battery positive voltage (B+) is applied via the entire seat forward switch contacts and the entire seat forward control circuit to the horizontal motor. The motor is grounded via the entire seat rearward switch contacts and the entire seat rearward control circuit to the motor. The motor runs in order to drive 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 (B+) and ground are applied on opposite circuits causing the motor to run in the opposite direction.

When the seat switch is operated to tilt the front of the seat up, battery positive voltage (B+) is applied via the front vertical up switch contacts and the front vertical up control circuit to the front vertical motor. The motor is grounded via the front vertical down switch contacts and the front vertical down control circuit to the motor. The motor runs in order to drive the front of the seat up until the switch is released. Tilting the front of the seat down works similarly to tilting the front of the seat up, except that battery positive voltage (B+) and ground are applied on opposite circuits causing the motor to run in the opposite direction.

When the seat switch is operated to tilt the rear of the seat up, battery positive voltage (B+) is applied via the rear vertical up switch contacts and the rear vertical up control circuit to the rear vertical motor. The motor is grounded via the rear vertical down switch contacts and the rear vertical down control circuit to the motor. The motor runs in order to drive the rear of the seat up until the switch is released. Tilting the rear of the seat down works similarly to tilting the rear of the seat up, except that battery positive voltage (B+) and ground are applied on opposite circuits causing the motor to run in the opposite direction.

When a seat switch is operated in order to move the entire seat to the up position, battery positive voltage (B+) is applied via both the front vertical up and rear vertical up switch contacts, through the front and rear vertical up control circuits to both vertical motors. The motors are grounded via the front and rear vertical down switch contacts and the front and rear vertical down control circuits to the motors. Both motors run in order to drive the entire seat up until the switch is released. Moving the entire seat down works similarly to moving the entire seat up, except that battery positive voltage (B+) and ground are applied on the opposite circuits causing the motor to run in the opposite direction.

When the seat recline switch is operated to move the seat back forward, battery positive voltage (B+) is applied via the recline forward switch contacts and the recline forward control circuit to the motor. The motor is grounded via the recline rearward switch contacts and the recline rearward control circuit to the motor. The motor runs in order to move the seat back forward until the switch is released. Moving the seat back rearward works similarly to moving the seat back forward, except that battery positive voltage (B+) and ground are applied on the opposite circuits causing the motor to run in the opposite direction.

When the headrest switch is operated to raise the headrest up, battery positive voltage (B+) is applied via the headrest up switch contacts and the headrest motor up control circuit to the motor. The motor is grounded via the headrest down switch contacts and the headrest motor down control circuit to the motor. The motor runs in order to move the headrest up until the switch is released. Moving the headrest down works similarly to moving the headrest up except that battery positive voltage (B+) and ground are applied on the opposite circuits causing the motor to run in the opposite direction.
