PASSENGER POWER SEAT
SWITCH
DESCRIPTION
Vehicles equipped with power seats utilize a eight/
six-way passenger power seat switch. This eight/six-
way power seat switch features two knobs ganged
together on the outboard seat cushion side shield.
Vehicles equipped with the eight-way, incorporate a
AIRBAGS. BEFORE
power rear seat riser motor. Vehicles with the six-
way do not.
The switch is secured to the back of the seat cush-
ion side shield with two screws. However, the control
knobs for the power seat switch must be removed
before the seat switch can be removed from the side
shield.
The power seat switch cannot be repaired. If one
switch is damaged or faulty, the entire power seat
switch assembly must be replaced.

OPERATION

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 or recliner adjuster motor. The selected
adjuster motor operates to move the seat track or
recliner through its drive unit in the selected direc-
tion 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 con-
tinue, or the motor may be damaged. See the owner's
manual in the vehicle glove box for more information
on the power seat switch functions and the seat
adjusting procedures.
DIAGNOSIS AND TESTING - PASSENGER
POWER SEAT SWITCH
(1) Remove the power seat switch, refer to the
Switch Removal and Installation procedures in this
section.
(2) Using an ohmmeter, check pin #1 of the power
seat switch connector for continuity to ground. It
should be present, If OK go to Step 3 , If NOT OK
repair the open ground circuit as required.
(3) Using an voltmeter, check pin #5 of the power
seat switch connector for approx. 12v. It should be
present, If OK go to Step 4 , If NOT OK repair the
open voltage supply circuit as required.
(4) Using an ohmmeter, perform the Seat Switch
Continuity Test table using (Fig. 7). If there is no
continuity at any of the switch positions, replace the
power seat switch.
