Power Seat Motor: Description and Operation
Power Seat Adjuster and Motors
SYSTEM OPERATION
The power recliner adjuster uses a reversible motor to operate the seat back recliner adjuster. The motor is connected to a gearbox that moves the
recliner adjuster through a screw-type drive unit.
When the power recliner switch is actuated, a battery feed and a ground path are applied through the switch contacts to the motor. The motor
operates to move the seat back in the selected direction until the switch is released, or until the travel limit of the power recliner 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 motor to run in the opposite direction.
The motor contains a self-resetting circuit breaker to protect it from overload. Consecutive or frequent resetting of the circuit breaker must not be
allowed to continue, or the motor may be damaged. Make the necessary repairs. The motor used on models with the optional memory system also
has a position potentiometer included in the motor assembly.
The power recliner adjuster and motor cannot be repaired, and is serviced only as a complete unit. If any component in this unit is faulty or
damaged, the entire power recliner adjuster and motor assembly must be replaced.
