Grand Cherokee 4WD Laredo V8-4.7L (2002)
Power Seat Motor: Description and Operation
RECLINER MOTOR
The ten-way power seat option includes an electrically operated seat back recliner mechanism. The only visible evidence of this option is the separate
power seat recliner switch control knob that is located on the outboard seat cushion side shield, just behind the other power seat switch control knob. The
power seat recliner switch is integral to the ten-way power seat switch unit, but is actuated with a separate switch knob.
Power Seat Recliner And Track
The power seat recliner unit is mounted in the place of a seat hinge on the outboard side of the seat. The upper hinge plate of the power seat recliner
mechanism is secured with two screws to the seat back frame and is concealed beneath the seat back trim cover and padding. The lower hinge plate and
the motor and drive unit of the power seat recliner mechanism is secured with two screws to the seat cushion frame, and is concealed by the outboard
seat cushion side shield.
The power seat recliner cannot be repaired. If the unit is faulty or damaged, it must be replaced. Refer to Bucket Seat Recliner in Body for the service
procedure.
The power seat recliner includes a reversible electric motor that is secured to the lower hinge plate of the recliner unit. The motor is connected to a
gearbox that moves the upper hinge plate of the power seat recliner through a screw-type drive unit. The driver side power seat recliner motor used on
models equipped with the optional memory system also has a position potentiometer integral to the motor assembly, which electronically monitors the
motor position.
