POWER LOCKS
DESCRIPTION
POWER LOCKS
The power lock system allows all of the doors to be
locked or unlocked electrically by operating a switch
on either front door trim panel. The power lock sys-
tem receives non-switched battery current through a
fuse in the Integrated Power Module (IPM), so that
the power locks remain operational, regardless of the
ignition switch position. The Body Control Module (BCM) locks the doors
automatically when the vehicle is driven beyond the
speed of 25.7 Km/h (15 mph), all doors are closed, the
accelerator pedal is depressed and the door lock actu- ation had not been previously activated. The rolling
door lock feature is customer programmable.
This vehicle also offers several customer program-
mable features, which allows the selection of several
optional electronic features to suit individual prefer-
ences. The power lock system for this vehicle can also be
operated remotely using the available Remote Key-
less Entry (RKE) system radio frequency transmit-
ters, if equipped.
AUTOMATIC DOOR LOCKS
When enabled, this feature will lock all of the door
locks if all of the doors are closed and the vehicle
speed goes above 25.7 km/h (15 mph). If a door
unlock has occurred, then the BCM will perform
another auto lock, if the doors did not electrically
unlock, another auto lock will not occur.

DIAGNOSIS AND TESTING - DOOR LOCK
MOTOR
Any diagnosis of the power lock system
should begin with the use of the DRB III tdiag-
nostic tool. For information on the use of the
DRB III t, refer to the appropriate Diagnostic
Service Manual. For complete circuit diagrams, refer to the appro-
priate wiring information. Verify battery condition before testing door lock
motor(s). To determine which motor is faulty, check each
individual door for electrical lock and unlock or dis-
connect the motor connectors one at a time, while
operating the door lock switch. In the event that
none of the motors work, the problem may be caused
by a shorted motor or a faulty switch. Disconnecting
the faulty motor will allow the others to work. To test an individual door lock motor, disconnect
the electrical connector from the motor. To lock the
door, connect a fused 12 volt power source to the pos-
itive pin of the lock motor and a ground wire to the
other pin. To unlock the door reverse the wire con-
nections at the motor pin terminals. If these results
are not obtained, replace the door latch.

POWER SEAT SYSTEM
DESCRIPTION
DESCRIPTION
The power seat system option allows the driver
and front seat passenger to electrically adjust their
seating positions for optimum control and comfort
using the power seat switches located on the out-
board seat cushion side shield of each front seat. The
driver side power front seat can be adjusted in eight
different directions: up, down, front up, front down,
rear up, rear down, forward, rearward and recliner
forward and rearward. The passenger side power
front seat can be adjusted in four different directions:
forward, rearward and recliner forward and rear-
ward. The power seat system receives battery current
through a 40 amp fuse in the Intelligent Power Mod-
ule and a 30 amp circuit breaker under the seat so
that the power seats remain operational, regardless
of the ignition switch position. WARNING: SOME VEHICLES ARE EQUIPPED WITH
SEATBACK MOUNTED AIRBAGS (Fig. 1). BEFORE
ATTEMPTING TO DIAGNOSE OR SERVICE ANY
SEAT OR POWER SEAT SYSTEM COMPONENT
YOU MUST FIRST DISCONNECT AND ISOLATE THE
BATTERY NEGATIVE CABLE. THEN WAIT TWO MIN-
UTES FOR THE SYSTEM CAPACITOR TO DIS-
CHARGE BEFORE FURTHER SYSTEM SERVICE.
THIS IS THE ONLY SURE WAY TO DISABLE THE

PASSENGER SEAT SWITCH
DESCRIPTION
Vehicles equipped with a passenger side power seat
utilize a four-way power seat switch. This four-way
power seat switch features two knobs ganged
together on the outboard seat cushion side shield. The switch is secured to the back of the seat cush-
ion side shield with two screws. However, the control
knobs for the seat switch unit 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 unit 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.

through a combination of worm-drive gearboxes and
screw-type drive units. Each of the four power seat
track motors used on models equipped with the
optional memory system incorporates a position
potentiometer integral to the motor assembly, which
electronically monitors the motor position. This
enables the memory system to function by referenc-
ing the motor positions programmed into the memory
seat/mirror module. The front and rear of the seat are operated by two
separate vertical adjustment motors. These motors
can be operated independently of each other, tilting
the entire seat assembly forward or rearward; or,
they can be operated in unison by selecting the
proper power seat switch functions, which will raise
or lower the entire seat assembly. A third motor is the horizontal adjustment motor, which moves the
seat track in the forward and rearward directions.
The forth motor is the recliner adjustment motor,
which moves the seat back in the forward and rear-
ward directions.
The power seat track unit cannot be repaired, and
is serviced only as a complete unit. If any component
in this unit is faulty or damaged, the entire power
seat track unit must be replaced.
OPERATION
When the driver side 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 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 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 - DRIVER POWER
SEAT TRACK
WARNING: SOME VEHICLES ARE EQUIPPED WITH
SEATBACK MOUNTED AIRBAGS. BEFORE
ATTEMPTING TO DIAGNOSE OR SERVICE ANY
SEAT OR POWER SEAT SYSTEM COMPONENT
YOU MUST FIRST DISCONNECT AND ISOLATE THE
BATTERY NEGATIVE CABLE. THEN WAIT TWO MIN-
UTES FOR THE SYSTEM CAPACITOR TO DIS-
CHARGE BEFORE FURTHER SYSTEM SERVICE.
THIS IS THE ONLY SURE WAY TO DISABLE THE
AIRBAG SYSTEM. FAILURE TO DO SO COULD
RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND POSSIBLE PERSONAL INJURY.
Actuate the driver side power seat switch to move
all three power seat track adjusters in each direction.
The power seat track adjusters should move in each
of the selected directions. If a power seat track
adjuster fails to operate in only one direction, move
the adjuster a short distance in the opposite direction
