DOOR LOCK MOTOR
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.

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. 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 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 in the power
seat switch connector receptacle 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 wire
harness connector for the power seat switch for bat-
tery current. 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, test the power seat switch
continuity as shown in the Test Table at the pins in
the switch connector receptacle (Fig. 3). If there is no
continuity at any of the switch positions, replace the
power seat switch.

PASSENGER POWER SEAT
TRACK
DESCRIPTION
The four-way passenger side power seat option
includes a electrically operated power seat track unit
located under the passenger side front seat. The

cle. Four bolts secure the bottom of the seat cushion
frame to the upper half of the power seat track unit.
Four additional bolts secure the seat back frame to
the power seat track unit.The passenger side power seat track unit includes
two reversible electric motors that are secured to the
upper half of the track unit. Each motor moves the
seat adjuster through a combination of worm-drive
gearboxes and screw-type drive units. The horizontal
adjustment motor moves the seat track in the for-
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.

AUTOMATIC SPEED CONTROL OVERSPEED
REDUCTION
DESCRIPTION
Transmission control software includes an auto-
matic speed control overspeed reduction feature. This
maintains vehicle speed at the selected set point
when descending a grade.
OPERATION
The TCM (on SBEC vehicles) (PCM on NGC vehi-
cles) first senses that the speed control is set. If the
set speed is exceeded by more than 4 mph (6.5
km/hr) and the throttle is closed, the TCM (on SBEC
vehicles) (PCM on NGC vehicles) causes the trans-
axle to downshift to THIRD gear. After downshifting,
the automatic speed control resumes normal opera-
tion. To ensure that an upshift is appropriate after
the set speed is reached, the TCM (on SBEC vehi-
cles) (PCM on NGC vehicles) waits until the speed
control system opens the throttle at least 6 degrees
before upshifting to OVERDRIVE again.
If the driver applies the brakes, canceling auto-
matic speed control operation with the transaxle still
in THIRD gear, the TCM (on SBEC vehicles) (PCM
on NGC vehicles) maintains this gear until the driver
opens the throttle at least 6 degrees to avoid an inap-
propriate upshift. The upshift is also delayed for 2.5
seconds after reaching the 6 degrees throttle opening
in anticipation that the driver might open the throt-
tle enough to require THIRD gear. This will avoid
unnecessary and disturbing transmission cycling. If
the automatic speed control RESUME feature is used
after braking, the upshift is delayed until the set
speed is achieved to reduce cycling and provide bet-
ter response.
DIAGNOSIS AND TESTING - ROAD TEST
Perform a vehicle road test to verify reports of
speed control system malfunction. The road test
should include attention to the speedometer. Speed-
ometer operation should be smooth and without flut-
ter at all speeds.
Flutter in the speedometer indicates a problem
which might cause surging in the speed control sys-
tem. The cause of any speedometer problems should
be corrected before proceeding. Refer to the Instru-
ment Cluster for speedometer diagnosis.
If a road test verifies an inoperative system, and
the speedometer operates properly, check for:
²A Diagnostic Trouble Code (DTC). If a DTC
exists, conduct tests per the Powertrain Diagnostic
Procedures manual.
²A misadjusted brake (stop) lamp switch. This
could also cause an intermittent problem.
²Loose or corroded electrical connections at the
servo. Corrosion should be removed from electrical
terminals and a light coating of Mopar Multipurpose
Grease, or equivalent, applied.
²Leaking vacuum reservoir.
²Loose or leaking vacuum hoses or connections.
²Defective one-way vacuum check valve.
²Secure attachment at both ends of the speed
control servo cable.
²Smooth operation of throttle linkage and throttle
body air valve.
²Conduct electrical test at PCM.
²Failed speed control servo. Do the servo vacuum
test.
CAUTION: When test probing for voltage or conti-
nuity at electrical connectors, care must be taken
not to damage connector, terminals or seals. If
these components are damaged, intermittent or
complete system failure may occur.

SWITCH
DESCRIPTION
There are two separate switch pods that operate
the speed control system and are located on the
steering wheel.
OPERATION
The speed control system has five separate resis-
tive switches that provide a single multiplexed
(MUX) voltage inputs to the PCM.The switch names
are: ON, OFF, SET, COAST, RESUME, ACCEL, TAP-
UP, COAST, and CANCEL. Based on conditions when
the buttons are pushed (and released), the five volt-
ages ranges provided to the PCM result in the follow-
ing functions: ON, OFF, SET, COAST, RESUME,
ACCEL, TAP-UP, TAP-DOWN, COAST, and CAN-
CEL. Refer to the Speed Control Section for more
information
Also the PCM receives an input from the brake
switch to sense whether the brake pedal has been
depressed. When the PCM receives the brake
depressed input, it turns off power to the speed con-
trol servo and disengages speed control. Also the
power to the servo is supplied through the brake
switch, which opens the circuit when the brake pedal
is depressed.
The individual switches cannot be repaired. If one
switch fails, the entire switch module must be
replaced.
REMOVAL
The speed control switches are mounted in the
steering wheel and wired through the clock spring
device under the airbag module.
WARNING: IF REMOVAL OF AIRBAG MODULE IS
NECESSARY, REFER TO THE RESTRAINT SYS-
TEMS SECTION FOR MORE INFORMATION.
(1) Remove the negative battery cable.
(2) Turn off ignition.

VACUUM RESERVOIR
DESCRIPTION
The vacuum reservoir is located in the engine com-
partment. It is made of plastic.
OPERATION
The reservoir stores engine vacuum. Manifold vac-
uum is supplied from the brake booster check valve.
The speed control vacuum supply hose has a check
valve at the source (brake booster) to maintain the
highest available vacuum level in the servo, reservoir
and vacuum hoses. When engine vacuum drops, as in
climbing a grade while driving, the reservoir supplies
the vacuum needed to maintain proper speed control
operation. The vacuum reservoir cannot be repaired
and must be replaced if faulty.

SENTRY KEY REMOTE ENTRY
MODULE
DESCRIPTION
The Sentry Key Remote Entry Module (SKREEM)
performs the functions of the Sentry Key Immobilizer
Module (SKIM), Remote Keyless Entry (RKE) Mod-
ule, and the Tire Pressure Monitoring (TPM) System
(previously part of the Electronic Vehicle Information
Center (EVIC).
The SKREEM is located in the same location as
the SKIM was and is mounted the same way. It looks
identical, but has added capabilities.
SENTRY KEY IMMOBILIZER
The Sentry Key Immobilizer System (SKIS)
authenticates an electronically coded Transponder
Key placed into the ignition and sends a valid/invalid
key message to the Powertrain Control Module
(PCM) based upon the results. The ªVALID/INVALID
KEYº message communication is performed using a
rolling code algorithm via the Programmable Com-
munication Interface (PCI) data bus. A ªVALID KEYº

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 rear wiper operation is required, the BCM
will provide ignition ON voltage to the rear wiper
motor (Export and ATC equipped vehicles only).
When the wiper switch is turned OFF, the BCM pro-
vides circuit ground to operate the motor until the
wipe cycle is complete and the wiper arm returns to
the base of the rear window.
Switch only offers an intermittent rear wiper
mode. The wiper motor will cycle every 7 seconds.
The intermittent delay time is also adjusted based
upon vehicle speed. With the vehicle traveling
greater than 50 mph, the cycle changes to every 5
seconds.
When rear washer is requested by depressing and
holding down the switch, the BCM then provides a
ground for the rear washer motor. Until the switch is
released, the motor will be in a continuous wipe
mode, then return to an intermittent wipe mode.

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.
WIPER/WASHER SWITCH RESISTANCE
SWITCH POSITION RESISTANCE BETWEEN
OFF 1 AND 2 = 23.9KV 5%
DELAY POSITION
1ST 1 AND 2 = 7.9KV 5%
2ND 1 AND 2 = 4.6KV 5%
3RD 1 AND 2 = 2.9KV 5%
4TH 1 AND 2 = 1.9KV 5%
5TH 1 AND 2 = 1.3KV 5%
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.
