Power Seat System Components
The power seat system consists of the following components:
| • | Driver seat adjuster switch--Controls the up, down, and recline operation
of the drivers seat |
| • | Driver seat horizontal motor--Moves the seat rearward and forward |
| • | Driver seat vertical motor--Moves the seat up and down |
| • | Driver seat horizontal motor--Moves the seat back to the recline
rearward/forward position |
| • | PWR SEAT 30 A circuit breaker--Located in the underhood fuse
block, and provides battery positive voltage to the power seat switch at all times |
Power Seat System Controls
The power seat system will operate any time the ignition is the ACC or RUN
position. The power seat switch controls the 3 bi-directional motors in all
up/down, forward/rearward and recline positions.
Power Seat Motor Operation
Each seat motor is reversible. The direction the seat or seat back travel is
dependent upon the polarity of the supply voltage. By reversing polarity of the supply
voltage the motor will move in one of its respective directions.
Power Seat Operation
Battery voltage is supplied to the driver seat adjuster switch through the battery
positive voltage circuit from the 30 A circuit breaker. The driver seat adjuster
switch receives constant ground from G 301. All of the seat motor control circuits
are connected to ground through the normally closed contacts of the driver seat adjuster
switch. When a driver seat adjuster switch is placed in any position other than normally
closed (Neutral), the seat motor control circuit is switched from ground to 12 volts
and the motor moves the seat in the requested direction. When the driver seat adjuster
switch is released all motor control circuits return to normally closed, or ground.
