POWER LOCK SWITCH
DESCRIPTION
The power lock system can be controlled by a two-
way momentary switch integral to the power window
and lock switch and bezel unit on the trim panel of
each front door. Each power lock switch is illumi-
nated by a Light-Emitting Diode (LED) that is inte-
gral to the switch paddle. The LED of each switch is
illuminated whenever the ignition switch is in the
On position.
The power lock switches and their LEDs cannot be
adjusted or repaired and, if faulty or damaged, the
entire power window and lock switch and bezel unit
must be replaced.
OPERATION
On models with a base version of the Central
Timer Module (CTM), the power lock switches are
hard-wired to the power lock motors. The power lock
switch provides the correct battery and ground feeds
to the power lock motors to lock or unlock the door
latches.
On models with a high-line or premium version of
the CTM, the power lock switch controls battery cur-
rent signals to the lock and unlock sense inputs of
the CTM. The CTM then relays the correct battery
and ground feeds to the power lock motors to lock or
unlock the door latches.
DIAGNOSIS AND TESTING - POWER LOCK
SWITCH
The Light-Emitting Diode (LED) illumination
lamps for all of the power window and lock switch
and bezel unit switch paddles receive battery current
through the power window circuit breaker in the
Junction Block (JB). If all of the LEDs are inopera-
tive in either or both power window and lock switch
and bezel units, be certain to diagnose the power
window system before replacing the switch unit.
(Refer to 8 - ELECTRICAL/POWER WINDOWS -
DIAGNOSIS AND TESTING). If only one LED in a
power window and lock switch and bezel unit is inop-
erative, replace the faulty switch and bezel unit.
Refer to the appropriate wiring information. The wir-
ing information includes wiring diagrams, proper
wire and connector repair procedures, details of wire
harness routing and retention, connector pin-out
information and location views for the various wire
harness connectors, splices and grounds.
(1) Check the fused B(+) fuse (Fuse 13 - 10
ampere) in the Junction Block (JB). If OK, go to Step
2. If not OK, repair the shorted circuit or component
as required and replace the faulty fuse.
(2) Check for battery voltage at the fused B(+) fuse
(Fuse 13 - 10 ampere) in the JB. If OK, go to Step 3.
If not OK, repair the open fused B(+) circuit between
the JB and the Power Distribution Center (PDC) as
required.
(3) Disconnect and isolate the battery negative
cable. Remove the power window and lock switch and
bezel unit from the door trim panel. Disconnect the
door wire harness connector for the power window
and lock switch unit from the switch connector recep-
tacle.
(4) Reconnect the battery negative cable. Check for
battery voltage at the fused B(+) circuit cavity of the
door wire harness connector for the power window
and lock switch unit. If OK, go to Step 5. If not OK,
repair the open fused B(+) circuit between the power
window and lock switch unit and the JB as required.

POWER MIRRORS
DESCRIPTION
AUTOMATIC DAY / NIGHT MIRROR
The automatic day/night mirror system is able to
automatically change the reflectance of the inside
rear view mirror in order to reduce the glare of head-
lamps approaching the vehicle from the rear. The
automatic day/night rear view mirror receives bat-
tery current through a fuse in the junction block only
when the ignition switch is in the On position.
OUTSIDE REAR VIEW MIRROR
The heated mirror option includes an electric heat-
ing grid behind the mirror glass in each outside mir-
ror, which can clear the mirror glass of ice, snow, or
fog. The heating grid receives fused battery current
through the heated mirror relay in the heater and air
conditioner control only when the ignition switch is
in the On position, and the heated mirror system is
turned on. (Refer to 8 - ELECTRICAL/HEATED
MIRRORS - DESCRIPTION) for more information.
Refer to the owner's manual in the vehicle glove
box for more information on the features, use and
operation of the power mirror system.
OPERATION
AUTOMATIC DAY / NIGHT MIRROR
A switch located on the bottom of the automatic
day/night mirror housing allows the vehicle operator
to select whether the automatic dimming feature is
operational. When the automatic day/night mirror isturned on, the mirror switch is lighted by an integral
Light-Emitting Diode (LED). The mirror will auto-
matically disable its self-dimming feature whenever
the vehicle is being driven in reverse.
Refer to the owner's manual in the vehicle glove
box for more information on the features, use and
operation of the automatic day/night mirror system.
OUTSIDE REAR VIEW MIRROR
The heated mirror option includes an electric heat-
ing grid behind the mirror glass in each outside mir-
ror, which can clear the mirror glass of ice, snow, or
fog. The heating grid receives fused battery current
through the heated mirror relay in the heater and air
conditioner control only when the ignition switch is
in the On position, and the heated mirror system is
turned on. (Refer to 8 - ELECTRICAL/HEATED
MIRRORS - OPERATION) for more information.
Refer to the owner's manual in the vehicle glove
box for more information on the features, use and
operation of the power mirror system.
AUTOMATIC DAY / NIGHT
MIRROR
DESCRIPTION
The automatic day/night mirror uses a thin layer
of electrochromic material between two pieces of con-
ductive glass to make up the face of the mirror.
When the mirror switch is in the On position, two
photocell sensors are used by the mirror circuitry to
monitor external light levels and adjust the reflec-
tance of the mirror.
8N - 10 POWER MIRRORSBR/BE

OPERATION
The ambient photocell sensor is located on the for-
ward-facing (windshield side) of the rear view mirror
housing, and detects the ambient light levels outside
of the vehicle. The headlamp photocell sensor is
located inside the rear view mirror housing behind
the mirror glass and faces rearward, to detect the
level of the light being received at the rear window
side of the mirror. When the circuitry of the auto-
matic day/night mirror detects that the difference
between the two light levels is too great (the light
level received at the rear of the mirror is much
higher than that at the front of the mirror), it begins
to darken the mirror.
The automatic day/night mirror circuitry also mon-
itors the transmission using an input from the
backup lamp circuit. The mirror circuitry is pro-
grammed to automatically disable its self-dimming
feature whenever it senses that the transmission
backup lamp circuit is energized.
The automatic day/night mirror is a completely
self-contained unit and cannot be repaired. If faulty
or damaged, the entire mirror assembly must be
replaced.

POWER SEAT SYSTEM
DESCRIPTION
The power seat system option allows the driver (or
passenger on SLT Plus with power seats) to electri-
cally adjust the seat position for optimum control and
comfort using the power seat switches located on the
outboard seat cushion side shield. The power seat
system allows the seating position to be adjusted for-
ward, rearward, front up, front down, rear up, or
rear down. The power seat system receives battery
current through a fuse in the Power Distribution
Center and a circuit breaker in the junction block,
regardless of the ignition switch position.
Extended cab (club cab and quad cab) models
equipped with the power seat option also feature a
power operated lumbar support in the seat back. The
power lumbar support allows the user to inflate or
deflate a bladder located in the lower seat back to
achieve optimum comfort and support in the lower lum-
bar region of the spinal column. The power lumbar sup-
port shares the battery feed circuit of the power seat
system.
The power seat system includes the power seat
adjuster and motors unit, the power lumbar support
bladder and electric pump (extended cab only), the
power seat switch, and the circuit breaker. Followingare general descriptions of the major components in
the power seat system. Refer to the owner's manual
in the vehicle glove box for more information on the
features, use and operation of the power seat system.
OPERATION
The power seat system allows the driver and/or
front passenger seating positions to be adjusted elec-
trically and independently using the separate power
seat switches found on the outboard seat cushion
side shield of each front seat. See the owner's manual
in the vehicle glove box for more information on the
features, use and operation of the power seat system.
DIAGNOSIS & TESTING - POWER SEAT
SYSTEM
Before any testing of the power seat system is
attempted, the battery should be fully-charged and all
wire harness connections and pins cleaned and tightened
to ensure proper continuity and grounds. For circuit
descriptions and diagrams, refer to Wiring Diagrams.
With the dome lamp on, apply the power seat
switch in the direction of the failure. If the dome
lamp dims, the seat may be jamming. Check under

POWER WINDOWS
DESCRIPTION
Power windows are available as factory-installed
optional equipment on this model. The power lock
system is included on vehicles equipped with the
power window option.
OPERATION
The power window system allows each of the front
door windows to be raised and lowered electrically by
actuating a switch on the trim panel of each respec-
tive door. Additionally, the master switch on the
driver side door trim panel allows the driver to raise
or lower the passenger side front door window. The
power window system receives battery feed through a
circuit breaker in the junction block, only when the
ignition switch is in the On position.
The power window system includes the power win-
dow switches on each front door trim panel, the cir-
cuit breaker in the junction block, and the power
window motors inside each front door. This group
covers diagnosis and service of only the electrical
components in the power window system. For service
of mechanical components, such as the regulator, lift
plate, window tracks, or glass refer to Group 23 -
Body.

DOW SWITCH - DIAGNOSIS AND TESTING). If not
OK, repair the circuit to ground as required.
ONE WINDOW INOPERATIVE
The window glass must be free to slide up and
down for the power window motor to function prop-
erly. If the glass is not free to move up and down, the
motor will overload and trip the integral circuit
breaker. To determine if the glass is free, disconnect
the regulator plate from the glass. Then slide the
window up and down by hand.
There is an alternate method to check if the glass
is free. Position the glass between the up and down
stops. Then, shake the glass in the door. Check that
the glass can be moved slightly from side to side,
front to rear, and up and down. Then check that the
glass is not bound tight in the tracks. If the glass is
free, proceed with the diagnosis that follows. If the
glass is not free, (Refer to 23 - BODY/DOOR -
FRONT/DOOR GLASS - REMOVAL).
(1) Disconnect and isolate the battery negative

vehicle with the inoperative window. Unplug the wire
harness connector from the switch and bezel unit.
(2) Connect the battery negative cable. Turn the
ignition switch to the On position. Check for battery
voltage at the fused ignition switch output (run) cir-
cuit cavity in the body half of the switch and bezel
unit wire harness connector. If OK, and the inopera-
tive power window is on the driver side, go to Step 4.
If OK, and the inoperative power window is on the
passenger side, go to Step 3. If not OK, repair the
open circuit to the junction block as required.
(3) Disconnect and isolate the battery negative
cable. Check for continuity between each of the two
master window switch right up/down control circuit
cavities in the body half of the passenger side switch
and bezel unit wire harness connector and a good
ground. In each case, there should be continuity. If
OK, go to Step 4. If not OK, repair the open circuit to
the driver side switch and bezel unit as required.
(4) Test the power window switch continuity.
(Refer to 8 - ELECTRICAL/POWER WINDOWS/
POWER WINDOW SWITCH - DIAGNOSIS AND
TESTING). If OK, go to Step 5. If not OK, replace
the faulty power window and lock switch and bezel
unit.
(5) Refer to the appropriate wiring information.
The wiring information includes wiring diagrams,
proper wire and connector repair procedures, details
of wire harness routing and retention, connector pin-
out information and location views for the various
wire harness connectors, splices and grounds. Check
the continuity in each circuit between the inoperative
power window and lock switch and bezel unit wire
harness connector cavities and the corresponding
power window motor wire harness connector cavities.
If OK, (Refer to 8 - ELECTRICAL/POWER WIN-
DOWS/WINDOW MOTOR - DIAGNOSIS AND TEST-
ING). If not OK, repair the open circuit(s) as
required.
NOTE: The passenger side power window switch
receives the ground feed for operating the passen-
ger side power window motor through the driver
side power window switch and wire harness con-
nector.
POWER WINDOW SWITCH
DESCRIPTION
The power windows are controlled by two-way
switches integral to the power window and lock
switch and bezel unit on the trim panel of each front
door. A second power window switch in the driver
side switch and bezel unit allows the driver to control
the passenger side window. A Light-Emitting Diode(LED) in the paddle of each switch is illuminated
whenever the ignition switch is in the On position.
OPERATION
The power window switch for the driver side front
door has an Auto label on it. This switch has a sec-
ond detent position beyond the normal Down position
that provides an automatic one-touch window down
feature. This feature is controlled by an electronic
circuit and a relay that are integral to the driver side
front door power window and lock switch unit.
The power window switches control the battery
and ground feeds to the power window motors. The
passenger side power window switch receives a
ground feed through the driver side power window
switch for operating the passenger side power win-
dow motor.
The power window and lock switch and bezel unit
cannot be repaired and, if faulty or damaged, the
entire switch and bezel unit must be replaced.
DIAGNOSIS AND TESTING - POWER WINDOW
SWITCH
The auto down feature of the driver side power
window switch is controlled by an electronic circuit
within the switch unit. The auto down circuitry is
activated when the driver side power window switch
is moved to the second detent in the Down direction.
The outputs from the auto down circuitry are carried
through the same switch pins that provide the nor-
mal down function. The auto down circuit cannot be
tested. If the driver side power window switch conti-
nuity tests are passed, but the auto down feature is
inoperative, replace the faulty driver side power win-
dow switch unit.
The Light-Emitting Diode (LED) illumination
lamps for all of the power window and lock switch
and bezel unit switch paddles receive battery current
through the power window circuit breaker in the
junction block. If all of the LEDs are inoperative in
either or both power window and lock switch and
bezel units and the power windows are inoperative,
perform the diagnosis for Power Window System in
this group. If the power windows operate, but any or
all of the LEDs are inoperative, the power window
and lock switch and bezel unit with the inoperative
LED(s) is faulty and must be replaced. For circuit
descriptions and diagrams, refer to the appropriate
wiring information. The wiring information includes
wiring diagrams, proper wire and connector repair
procedures, details of wire harness routing and
retention, connector pin-out information and location
views for the various wire harness connectors, splices
and grounds.

in the center of the steering wheel and also into the
passenger airbag door on the instrument panel above
the glove box (Fig. 1). Vehicles with the airbag sys-
tem can also be identified by the airbag indicator,which will illuminate in the instrument cluster for
about seven seconds as a bulb test each time the
ignition switch is turned to the On position.
The dual front airbag system consists of the follow-
ing major components, which are described in further
detail elsewhere in this service manual:
²Airbag Control Module- The Airbag Control
Module (ACM) is located on a mount on the floor
panel transmission tunnel, below the center of the
instrument panel.
²Airbag Indicator- The airbag indicator is inte-
gral to the ElectroMechanical Instrument Cluster
(EMIC), which is located on the instrument panel in
front of the driver.

²Clockspring- The clockspring is located near
the top of the steering column, directly beneath the
steering wheel.
²Driver Airbag- The driver airbag is located in
the center of the steering wheel, beneath the driver
airbag trim cover.
²Driver Knee Blocker- The driver knee blocker
is a molded plastic structural unit secured to the
back side of and integral to the instrument panel
steering column opening cover.
²Passenger Airbag- The passenger airbag is
located on the instrument panel, beneath the passen-
ger airbag door on the instrument panel above the
glove box on the passenger side of the vehicle.
²Passenger Airbag On/Off Switch- The pas-
senger airbag on/off switch is located in a dedicated
opening in the upper right corner of the instrument
panel cluster bezel, to the right of the center panel
outlets of the climate control system.
²Passenger Knee Blocker- The passenger knee
blocker is a structural reinforcement that is integral
to and concealed within the glove box door.
The ACM and the EMIC each contain a central
processing unit and programming that allow them to
communicate with each other using the Chrysler Col-
lision Detection (CCD) data bus network. This
method of communication is used for control of the
airbag indicator on all models. (Refer to 8 - ELEC-
TRICAL/ELECTRONIC CONTROL MODULES/
COMMUNICATION - DESCRIPTION).
Hard wired circuitry connects the airbag system
components to each other through the electrical sys-
tem of the vehicle. These hard wired circuits are
integral to several wire harnesses, which are routed
throughout the vehicle and retained by many differ-
ent methods. These circuits may be connected to each
other, to the vehicle electrical system, and to the air-
bag system components through the use of a combi-
nation of soldered splices, splice block connectors,and many different types of wire harness terminal
connectors and insulators. Refer to the appropriate
wiring information. The wiring information includes
wiring diagrams, proper wire and connector repair
procedures, further details on wire harness routing
and retention, as well as pin-out and location views
for the various wire harness connectors, splices and
grounds.
OPERATION
The airbag system is referred to as a supplemental
restraint system because it was designed and is
intended to enhance the protection for the front seat
occupants of the vehicleonlywhen used in conjunc-
tion with the seat belts. It is referred to as a passive
system because the vehicle occupants are not
required to do anything to make it work. The pri-
mary passenger restraints in this or any other vehi-
cle are the standard equipment factory-installed seat
belts. Seat belts are referred to as an active restraint
because the vehicle occupants are required to physi-
cally fasten and properly adjust these restraints in
order to benefit from them. The vehicle occupants
must be wearing their seat belts in order to obtain
the maximum safety benefit from the factory-in-
stalled airbag system.
The airbag system electrical circuits are continu-
ously monitored and controlled by a microprocessor
and software contained within the Airbag Control
Module (ACM). An airbag indicator in the ElectroMe-
chanical Instrument Cluster (EMIC) lights for about
seven seconds as a bulb test each time the ignition
switch is turned to the On or Start positions. Follow-
ing the bulb test, the airbag indicator is turned on or
off by the ACM to indicate the status of the airbag
system. If the airbag indicator comes on at any time
other than during the bulb test, it indicates that
there is a problem in the airbag system electrical cir-
cuits. Such a problem may cause the airbags not to
deploy when required, or to deploy when not
required.
The clockspring on the top of the steering column
allows a continuous electrical circuit to be main-
tained between the stationary steering column and
the driver airbag inflator, which rotates with the
steering wheel. The passenger airbag on/off switch
allows the passenger side airbag to be disabled when
circumstances necessitate that a child, or an adult
with certain medical conditions be placed in the front
passenger seating position. Refer to the owner's man-
ual in the vehicle glove box for specific recommenda-
tions concerning the specific circumstances where the
passenger airbag on/off switch should be used to dis-
able the passenger airbag.
