ward and rearward directions. The recliner adjust-
ment motor moves the seat back in the forward and
rearward 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 a passenger 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.

TRANSPONDER KEY
DESCRIPTION
The Sentry Key Immobilizer System (SKIS) uses a
transponder chip that is integral to each ignition key
(Fig. 1) to communicate with the Sentry Key Immo-
bilizer Module (SKIM). Ignition keys are supplied
with the vehicle when it is shipped from the factory.
The transponder chip is undermolded within the
head of the key. This undermold is hidden beneath
an overmolded rubber cap.
OPERATION
Each Sentry Key has a unique transponder identi-
fication code permanently programmed into it by the
manufacturer. Likewise, the SKIM has a unique
9Secret Key9code programmed into it by the manu-
facturer as well. When a Sentry Key is programmed
into the memory of the SKIM, the SKIM stores the
transponder identification code from the Sentry Key,
and the Sentry Key learns the9Secret Key9code from
the SKIM. Once the Sentry Key learns the9Secret
Key9code of the SKIM, it is also permanently pro-

WIPERS/WASHERS
DESCRIPTION
FRONT WIPER/WASHER SYSTEM
The windshield wipers can be operated with the
windshield wiper switch when the ignition switch is
in the RUN or ACCESSORY positions. The wind-
shield wiper system is protected by a 30 amp fuse (9)
located in the Power Distribution Center (PDC) part
of the Integrated Power Module (IPM) in the engine
compartment. The wiper/washer switch is integral tothe multi-function switch. It is a resistive MUX
switch that sends inputs to the BCM to operate the
wiper/washer system.
REAR WIPER/WASHER SYSTEM
The rear windshield wiper and washers can be
operated when the ignition switch is in the RUN or
ACCESSORY positions.
RSWIPERS/WASHERS8R-1
ProCarManuals.com

OPERATION
FRONT WIPER/WASHER SYSTEM
The windshield washer circuit is protected by a 15
amp Cartridge Fuse located in the IPM. The wiper
motor has permanent magnetic fields. The speeds are
determined by current flow to the appropriate set of
brushes inside the motor. The current flow is con-
trolled by the multi-function switch. The high speed/
low speed relays are located in the IPM. The speed
sensitive intermittent wiper is controlled by the Body
Control Module (BCM). The intermittent mode, with
the vehicle traveling greater than 10.4 mph, has a
range of 0.5 to 18 seconds. With the vehicle traveling
less than 10.4 mph, the time delay doubles to a
range of 1 to 36 seconds. The wiper arms will park at
the base of the windshield just above the cowl cover
after the wiper switch is turned OFF.
The windshield wiper motor and linkage is located
in an integral wiper unit at the rear of the engine
compartment. The wiper unit must be removed to
gain access to the wiper motor.
REAR WIPER/WASHER SYSTEM
When continuous rear wiper operation is required,
the BCM will provide ignition ON voltage to the rear
wiper motor. When the wiper switch is turned OFF,
the BCM provides circuit ground to operate the
motor until the wipe cycle is complete and the wiper
arm returns to the base of the rear window.
When intermittent rear wiper mode is selected, the
wiper motor will cycle every 7 seconds. The intermit-
tent delay time is also adjusted based upon vehicle
speed. With the vehicle traveling greater than 50
mph, the cycle changes to every 5 seconds.
DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - FRONT WIPER
SYSTEM
The windshield wiper system operates in several
modes:
²Low and high speed normal wipe
²Speed sensitive intermittent wipe
²Wipe after wash
²Park (switch OFF)
The windshield wiper circuits are continuously
monitored and controlled by the Body Control Mod-
ule (BCM). If a problem occurs in the electronic com-
ponents, wiring, switch (except integral motor park
switch) and wiper motor a Diagnostic Trouble Code
(DTC) will be stored in the BCM memory. DTC's can
be retrieved using a DRB IIItscan tool. Refer to the
proper Body Diagnostic Procedures manual for DTC
descriptions and retrieval information.The windshield wiper park switch and circuit is
monitored by the BCM. The park switch and circuit
can be tested using the Wiper System Diagnosis
table.
DIAGNOSIS AND TESTING - FRONT
WIPER/WASHER SWITCH
(1) Remove the multi-function switch (Refer to 8 -
ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/
MULTI-FUNCTION SWITCH - REMOVAL).
(2) Using an ohmmeter check resistance readings
between switch pins. Refer to the WIPER/WASHER
SWITCH RESISTANCE table.

LOW 1 AND 2 = 670V 5%
HIGH 1 AND2=240V 5%
WASH 1 AND 4 = 5.9KV 5%
DIAGNOSIS AND TESTING - FAILED PARK
SWITCH
If the wiper park switch has failed, the windshield
wipers will operate as follows:
²SWITCH OFF- Wipers stop in current location
regardless of the park signal.
²INTERMITTENT MODE- Wipers operate con-
tinuously or at low speed for one or more extra
wipes.
²LOW SPEED- Wipers operate at low speed.
²HIGH SPEED- Wipers operate at high speed.
²WIPE AFTER WASH- Wipers operate at low
speed in any mode setting. Wipers operate only while
the wash button is depressed with switch in the OFF
mode and wipers stop in mid-cycle when button is
released.
The windshield wiper park switch and circuit is
monitored by the BCM. The park switch and circuit
can be tested using the WIPER SYSTEM DIAGNO-
SIS table.
