POWER SEAT SWITCH
DESCRIPTION
Vehicles equipped with the power seat option utilize a
six-way power seat switch (2). This six-way power
seat switch features one seat cushion shaped knob,
visible on the outboard seat cushion side shield.
The switch is secured to the back of the seat cushion
side shield with two screws. However, the control knob
must be removed before the seat switch can be
removed from the side shield.
The individual switches internal to the power seat
switch assembly cannot be repaired. If one switch is
damaged or faulty, the entire power seat switch
assembly must be replaced.
OPERATION
The power seat tracks can be adjusted in six different ways using the power seat switches. See the owner’s manual
in the vehicle glove box for more information on the power seat switch functions and the seat adjusting procedures.
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 motor. 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 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 seat track 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 dam-
aged.
DIAGNOSIS AND TESTING
POWER SEAT SWITCH
For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wir-
