CLEANING AND INSPECTION
HEADLAMP CLEANING
This vehicle is equipped with plastic headlights
that are lighter and less susceptible to stone break-
age than glass headlights.
This plastic is not as scratch resistant as glass and
therefore a different lens cleaning procedures must
be followed.
To minimize the possibility of scratching the lenses
and reducing light output, avoid wiping with a dry
cloth. To remove road dirt, wash with a mild soap
solution followed by rinsing with water.
Do not use abrasive cleaning components, solvents,
steel wool or other aggressive material to clean the

GENERAL INFORMATION
INTRODUCTION
The Body Control Module (BCM) locks or unlocks
the doors when an actuation input signal from a door
lock switch or Remote Keyless Entry Module (RKE)
is received. The BCM signals lock and unlock relays
in the Junction Block to actuate the door lock motors.
The front doors, sliding door(s) and liftgate are
equipped with actuator motors to lock or unlock the
latch mechanisms. The front door lock actuator motor
is not serviced separately from the door latch. The
BCM locks the doors and liftgate automatically when
the vehicle is driven beyond the speed of 25.7 Km/h
(16 mph). The automatic door lock feature can be dis-
abled if desired. All doors and liftgate can be locked
or unlocked using mechanical button or key cylinder
methods.
DESCRIPTION AND OPERATION
AUTOMATIC DOOR LOCK FEATURE
The vehicle comes with two options for power door
locks:
²Rolling automatic lock (ENABLE), doors auto-
matically lock at approximately at 25.7 Km/h (16
mph).
²No rolling automatic lock (DISABLE), doors do
not automatically lock when the vehicle is moving.
The BCM is equipped with a disable feature to
stop the speed sensitive automatic door locks from
functioning. The DISABLE feature can be switched
ON or OFF as desired. When the system is DIS-
ABLED the door locks will operate normally, but will
not lock automatically when the vehicle is rolling.
When the door locks are ENABLED the door locks
will automatically lock when the vehicle is moving at
about 25.7 Km/h (16 mph).
DOOR LOCK CIRCUIT PROTECTION
The BCM controls the door lock relay's operation.
If the door lock switch is actuated continuously for
more than one second the BCM will interrupt the
relay circuit. The door lock system is protected by a
40 amp fuse located in the Power Distribution Center
(PDC). The LOCK and UNLOCK relays are located
in the Junction Block. The Power Distribution Center
is located along side of the battery. The lock motors
are protected with Positive Temperature Coefficient
(PTC) device that prevents motor burn out.

GENERAL INFORMATION
INTRODUCTION
Power seats can be adjusted in eight directions; up,
down, forward, back, tilt forward, or tilt rearward.
Four reversible motors and a transmission located on
the seat tracks provide the various seat movements.
The electrical circuit is protected by a 40 amp fuse in
the Power Distribution Center (PDC) and a 30 amp
circuit breaker located in the wire harness under the
driver's seat.
DIAGNOSIS AND TESTING
DIAGNOSTIC PROCEDURES
Before testing the seat functions, verify that the
battery is fully charged and the terminals cleaned
and tightened to ensure proper connections. If the
battery is not fully charged, refer to Group 8A Bat-
tery for proper testing procedures.
The following test will determine if the circuit is
complete through the body harness to the switch:
Using a voltmeter, verify the condition of the power
seat circuit breaker located under the driver's seat.
The circuit breaker also protects the passenger side
power seat track circuit. Check both sides of the cir-
cuit breaker connector for voltage, on the wire side.
²If not OK replace circuit breaker.
²If battery voltage is detected on both sides of the
circuit breaker. Refer to Seat Motor in the Diagnostic
and Testing in this section.²If seat motors test OK, refer to the Seat Switch
in the Diagnostic and Testing in this section.
²Refer to Group 8W Wiring Diagrams for wire
circuit information.
SEAT MOTORS
(1) Remove power seat switch from seat. Refer to
Group 23 Body for procedures.
(2) Disconnect wire connector.
(3) Using a voltmeter check for battery voltage at
Pin 5. Using an ohmmeter, check Pin 1 for ground.
(4) To test the seat motors, refer to (Fig. 1) and
verify proper seat responses. Using two jumper
wires, connect one to a battery supply and the other
to a ground. Connect the other ends to the seat wire
harness connector as described in (Fig. 1). If any
motor fails to operate, check wire connectors to the
motor. If not OK, repair as necessary. If OK, replace
seat motor/track assembly.
POWER SEAT SWITCH
(1) Remove power seat switch from seat. Refer to
Group 23 Body for procedures.
(2) Using an ohmmeter, perform the switch conti-
nuity tests in (Fig. 2). If there is no continuity at any
of the switch positions, replace switch.

GENERAL INFORMATION
INTRODUCTION
Memory Seat and Mirrors system is available only
on Town and Country (Luxury Class) vehicles.
Refer to Group 8W, Wiring Diagrams for circuit
information and component locations. Refer to the
proper Body Diagnostic Procedures manual for addi-
tional diagnostic information.
The Memory Seat/Mirror Module (MSM Module) is
mounted under the driver's seat, on the inboard
upper track with Torx head screws. The MSM Mod-
ule provides the driver with an adjustable seat,
recliner, and power side view mirror positioning con-
troller that remembers stored positions and will
recall those positions on command.
The Memory Seat/Mirror Module reads all seat and
recliner switch inputs and operates the seat and
recliner motors in response to switch actuation. The
MSM Module monitors position sensing potentiome-
ters (mounted on the motors) for seat and recliner
positioning.
The MSM Module operates the power side view
mirror motors through solid state drivers (electronic
switches) in the recall mode only, and follows the
glass face position by means of rheostats built into
the motor pack assembly of the mirrors. Normal elec-
trical operation of the mirrors is accomplished by
actuation of the power mirror switch.
The Memory Seat/Mirror Module monitors the mem-
ory switches and has the capability to store desired
positions in non-volatile memory in response to a valid
input sequence. Refer to Memory Selector Switches (1,
2, and S) and Remote Keyless Entry (RKE) Data Link.
The memory seat/mirror module also can activate the
previously described motors in response to a recall
request from an individual memory switch.
The Memory Seat/Mirror Module monitors a data
link between the RKE receiver and the Body Control
Module (BCM) and will respond to stored information
or modify stored information when requested by a
valid data stream.
The Memory Seat/Mirror Module is connected to
the system through a seat wiring harness that inter-
faces will all of the components within the seat struc-
ture, and with electrical distribution wiring harness
connections to the non-seat mounted components.
The module operates the seat and recliner motors
through relays: four dedicated to track forward/rear-
ward, track front up/down, track rear up/down, and
recliner forward/rearward. A fifth relay controls the
direction of operation of those motors.
DESCRIPTION AND OPERATION
POWER SIDE VIEW MIRROR POSITION SENSING
The mirror switch on the instrument panel oper-
ates the outside rear view mirrors independently of
the memory seat/mirror module. The module acti-
vates the mirror motors only when in its recall mode.
The side view mirrors have position sensing rheo-
stats built into each side view mirror vertical and
horizontal motor assembly. These rheostats provide a
sense voltage to the memory seat/mirror module that
indicates where the mirror is moving to or where its
position is at when the module is activated but the
mirror motor is not moving.
MEMORY SELECTOR SWITCHES
The memory selector switches are mounted on the
driver's door trim panel within easy reach of the
driver. They provide a means to set or recall either of
