lower outboard side of the seat cushion on the seat cushion side shield on all models. Refer to the owner's manual in the vehicle glove box for more
information on the power seat switch functions and the seat adjusting procedures.
The individual switches in the power seat switch module cannot be repaired. If one switch is damaged or faulty, the entire power seat switch module
must be replaced.
When a power 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.
No power seat switch should be held applied in any direction after the adjuster has reached its travel limit. The power seat adjuster motors each contain a
self-resetting circuit breaker to protect them from overload. However, consecutive or frequent resetting of the circuit breaker must not be allowed to
continue, or the motor may be damaged.
LUMBAR CONTROL SWITCH
The power lumbar seat option includes an electrically operated lumbar support mechanism. A single two-way momentary power lumbar switch is integral
with the power seat switches. The power lumbar switch is secured to the back of the seat cushion side shield with screws, and the switch paddle protrudes
through a hole to the outside of the shield. The switch paddle is located in a shallow depression molded into the outer surface of the seat cushion side
shield that helps to shroud it from unintentional actuation when entering or leaving the vehicle.
The power lumbar switches cannot be adjusted or repaired and, if faulty or damaged, the seat switch assembly must be replaced.
When the power lumbar switch paddle is actuated, a battery feed and a ground path are applied through the switch contacts to the power lumbar adjuster
motor. The motor operates to move the lumbar adjuster 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 motor to run in the opposite direction.
The power lumbar switch should not be held applied in either direction after the adjuster has reached its travel limit. The power lumbar adjuster motor
contains a self-resetting circuit breaker to protect it from overload. However, consecutive or frequent resetting of the circuit breaker must not be allowed
to continue, or the motor may be damaged.
