Power Seats - Operation

OPERATION

The power seat system receives battery current through a fuse in the Power Distribution Center (PDC) at all times.

When a power seat switch is actuated, a battery feed and a ground path are applied through the power seat switch contacts to the appropriate motor or motors. The motor and drive unit operate to move the seat adjuster or lumbar support (when equipped) in the selected direction until the switch is released, or until the travel limit of the drive unit is reached. When the switch is moved in the opposite direction, the battery feed and ground path to the motor is reversed through the switch contacts. This causes the motor to run in the opposite direction.

The motors, gearboxes and linkage for the power seat adjuster and power lumbar support cannot be adjusted or serviced separately. If a motor, gearbox or linkage for the seat adjuster or lumbar support becomes inoperative or damaged, the entire power seat adjuster or the seat back frame assembly must be replaced (Refer to Body/Seats).
