Seats: Description and Operation

POWER SEAT SYSTEM
The power seat system on this model allows the driver to electrically adjust their seating positions in eight directions for optimum control and comfort, using the power seat switch located on the outboard seat cushion side shield. The power drivers seat can be adjusted forward, rearward, up, down, front up, front down, rear up and rear down. The power seat system receives battery current through a circuit breaker in the fuseblock module, regardless of the ignition switch position.

The power seat system includes the following components:
- Power seat switch
- Power seat system fuse and circuit breaker
- Power seat track and motor assembly.

Following are general descriptions and operations for the major components in the power seat system.

When a power seat switch control knob or knobs are actuated, a battery feed and a ground path are applied through the switch contacts to the power seat track (adjuster motors). The selected adjuster motor operates to move the seat track through its drive unit in the selected direction until the switch is released, or until the travel limit of the seat track is reached. When the switch is moved in the opposite direction, the battery feed and ground path to the motor(s) are reversed through the switch contacts. This causes the seat track mounted motor to run in the opposite direction.

See the owner's manual in the vehicle glove box for more information on the features, use and operation of the power seat system.

DRIVER POWER SEAT SWITCH
The power seat can be adjusted in eight different ways using the power seat switch. The switch is located in a bezel on the lower inboard side of the seat cushion frame. Refer to the owner's manual for more information on the power seat switch functions and the seat adjusting procedures.

The individual switches in the power seat switch unit cannot be repaired. If one switch is damaged or faulty, the entire power seat switch unit must be replaced.

When a power seat switch control knob or knobs are actuated, a battery feed and a ground path are applied through the switch contacts to the power seat track or recliner adjuster motor. The selected adjuster motor operates to move the seat track or recliner through its drive unit in the selected direction until the switch is released, or until the travel limit of the adjuster is reached. When the switch is moved in the opposite direction, the battery feed and ground path to the motor are reversed through the switch contacts. This causes the adjuster motor to run in the opposite direction.

POWER SEAT TRACK
There are three reversible motors that operate the power seat track. The motors are connected to wormdrive gearboxes that move the seat track through a combination of screw-type drive units.

The front and rear of a seat are operated by different motors. They can be raised or lowered independently of each other. When the center seat switch is pushed to the Up or Down position, both the front and rear motors operate in unison, moving the entire seat up or down. The forward-rearward motor is operated by pushing the center seat switch to the Forward or Rearward position.

Each motor contains a self-resetting circuit breaker to protect it from overload. Consecutive or frequent resetting of the circuit breakers must not be allowed to continue, or the motors may be damaged.

The power seat track and motors cannot be repaired, and are serviced only as a complete unit. If any component in this unit is faulty or damaged, the entire power seat track and motors assembly must be replaced.

When a power seat switch control knob or knobs are actuated, a battery feed and a ground path are applied through the switch contacts to the power seat track (adjuster motors). The selected adjuster motor operates to move the seat track through its drive unit in the selected direction until the switch is released, or until the travel limit of the seat track is reached. When the switch is moved in the opposite direction, the battery feed and ground path to the motor(s) are reversed through the switch contacts. This causes the seat track mounted motor to run in the opposite direction.
