Power Seats: Notes
The power seat system can consist of the following components:
| 1 - Power Lumbar Switch |
| 5 - Power Lumbar Cell |
| 2 - Power Seat Switch |
| 6 - Power Seat Motor Fore/Aft |
| 3 - Power Lumbar Motor |
| 7 - Power Seat Motor Up/Down |
| 4 - Power Seat Motor Recliner |
The power seat system allows the seat passenger to electrically adjust the seating positions using the power seat switch located on the outboard seat cushion side shield.
The power seat system is a 8-way adjustable seat cushion track with a two-way power seat back. The power seats can be adjusted up, down, forward, rearward, recliner forward, and recliner rearward. An equipped two-way power lumbar support can be adjusted forward and rearward.
The power seat adjuster contains reversible motors that are connected to worm-drive gearboxes that move the seat adjusters through screw-type drive units. These motors are the height adjust motor and the front tilt motor. The third motor on the power seat adjuster is responsible for the fore and aft movement of the power seat. The fore/aft motor is a reversible motor that is connected through two flex drive cables to a worm-drive gearbox that moves the seat adjuster through a screw-type drive unit. Each motor contains a self-resetting circuit breaker to protect it from overload. Consecutive or frequent resetting of the circuit breakers may damaged the motors.
