POWER WINDOWS
DESCRIPTION
The power window system allows each of the door
windows to be raised and lowered electrically by
actuating a switch on the center console. A master
switch on the front of the center console allows the
driver to raise or lower each of the passenger door
windows and to lock out the individual switches on
the rear of the center console from operation. The
power window system receives battery feed through
fuse 13 in the Power Distribution Center (PDC), only
when the ignition switch is in the RUN or ACCES-
SORY position.
OPERATION
WINDOW SWITCH
The power window switches control the battery
and ground feeds to the power window motors. Both
of the rear door power window switches receive their
battery and ground feeds through the circuitry of the
front window switch. When the power window lock-
out switch is in the Lock position, the battery feed
for the rear door window switches is interrupted.
WINDOW MOTOR
Front door window lift motors use permanent type
magnets. The B+ and ground applied at the motor
terminal pins will cause the motor to rotate in one
direction. Reversing current through the motor ter-
minals will cause the motor to rotate in the opposite
direction.
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.
DIAGNOSIS AND TESTING - POWER
WINDOWS
WIRING VOLTAGE TEST
The following wiring test determines whether or
not voltage is continuous through the body harness
to the front switch.
(1) Remove the power window switch and bezel
(Refer to 8 - ELECTRICAL/POWER WINDOWS/
POWER WINDOW SWITCH - REMOVAL).
(2) Disconnect wire connector from back of power
window switch.
(3) Switch ignition to the ON position.
(4) Connect the clip end of a 12 volt test light to
Pin 14 of the window switch harness connector.
Touch the test light probe to Pin 10.
²If the test light illuminates, the wiring circuit
between the battery and switch is OK.
²If the lamp does not illuminate, first check fuse
13 in the Power Distribution Center (PDC). If fuse 13
is OK, then check for a broken wire.
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.
POWER WINDOW MOTOR TEST
If the power window motor is receiving proper cur-
rent and ground and does not operate, proceed with
motor test. Refer to the appropriate wiring informa-
tion. The wiring information includes wiring dia-
grams, proper wire and connector repair procedures,
details of wire harness routing and retention, connec-
tor pin-out information and location views for the
various wire harness connectors, splices and grounds.
(1) Remove front door trim panel as necessary to
gain access to power window motor wire connector
KJPOWER WINDOWS 8N - 21

(Refer to 23 - BODY/DOOR - FRONT/TRIM PANEL -
REMOVAL).
(2) Disconnect power window motor wire connector
from door harness.
(3) Using two jumper wires, connect one to a bat-
tery (+) source and the other to a good ground (-).
(4) Connect the Negative (-) jumper probe to one of
the motor connector terminals.
(5) Momentarily touch the Positive (+) jumper
probe to the other motor connector terminal.
When positive probe is connected the motor should
rotate in one direction to either move window up or
down. If window is all the way up or down the motor
will grunt and the inner door panel will flex when
actuated in that one direction.
(6) Reverse jumper probes at the motor connector
terminals and window should now move in opposite
direction. If window does not move or grunt, replace
the motor.
If window moved completely up or down, reverse
the jumper probes and cycle window to the opposite
position to verify full operation.
If motor grunts and does not move, verify that reg-
ulator is not binding.
WINDOW MOTOR
REMOVAL
The window motor is incorporated into the window
regulator assembly. If the window motor requires
replacement, the window regulator must be replaced.

is located on the back side of each vertical member of
the radiator support.
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 Knee Blocker- The passenger knee
blocker is a structural reinforcement that is integral
to and concealed within the glove box door.
²Seat Belt Tensioner- The seat belt tensioner
is integral to the driver side front seat belt retractor
unit on vehicles equipped with dual front airbags.
²Side Impact Airbag Control Module-Two
Side Impact Airbag Control Modules (SIACM) are
used on vehicles with the optional side curtain air-
bags, one left side and one right side. One SIACM is
located behind the B-pillar trim near the base of each
B-pillar.
²Side Curtain Airbag- In vehicles equipped
with this option, a side curtain airbag is located on
each inside roof side rail above the headliner, and
extends from the A-pillar to just beyond the C-pillar.
The ACM, both SIACMs, and the EMIC each con-
tain a central processing unit and programming that
allow them to communicate with each other using
the Programmable Communication Interface (PCI)
data bus network. This method of communication is
used by the ACM for control of the airbag indicator
on all models equipped with dual front airbags.
(Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES/COMMUNICATION - DESCRIP-
TION).
Hard wired circuitry connects the supplemental
restraint system components to each other through
the electrical system of the vehicle. These hard wired
circuits are integral to several wire harnesses, which
are routed throughout the vehicle and retained by
many different methods. These circuits may be con-
nected to each other, to the vehicle electrical system,
and to the supplemental restraint system compo-
nents through the use of a combination of soldered
splices, splice block connectors, and many different
types of wire harness terminal connectors and insu-
lators. 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
ACTIVE RESTRAINTS The primary passenger
restraints in this or any other vehicle are the stan-
dard equipment factory-installed seat belts. Seat
belts are referred to as an active restraint because
the vehicle occupants are required to physically fas-ten and properly adjust these restraints in order to
benefit from them. See the owner's manual in the
vehicle glove box for more information on the fea-
tures, use and operation of all of the factory-installed
active restraints.
PASSIVE RESTRAINTS The passive restraints
system is referred to as a supplemental restraint sys-
tem because they were designed and are intended to
enhance the protection for the vehicle occupants of
the vehicleonlywhen used in conjunction with the
seat belts. They are referred to as passive systems
because the vehicle occupants are not required to do
anything to make them operate; however, the vehicle
occupants must be wearing their seat belts in order
to obtain the maximum safety benefit from the facto-
ry-installed supplemental restraint systems.
The supplemental restraint system electrical cir-
cuits are continuously monitored and controlled by a
microprocessor and software contained within the
Airbag Control Module (ACM) and, on vehicles
equipped with the side curtain airbags, both Side
Impact Airbag Control Modules (SIACM). An airbag
indicator in the ElectroMechanical Instrument Clus-
ter (EMIC) illuminates for about seven seconds as a
bulb test each time the ignition switch is turned to
the On or Start positions. Following the bulb test,
the airbag indicator is turned on or off by the ACM
to indicate the status of the supplemental restraint
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 supplemental restraint sys-
tem electrical circuits. Such a problem may cause air-
bags not to deploy when required, or to deploy when
not required.
Deployment of the supplemental restraints
depends upon the angle and severity of an impact.
Deployment is not based upon vehicle speed; rather,
deployment is based upon the rate of deceleration as
measured by the forces of gravity (G force) upon the
impact sensors. When an impact is severe enough,
the microprocessor in the ACM or the SIACM signals
the inflator unit of the airbag module to deploy the
airbag. The seat belt tensioner is provided with a
deployment signal by the ACM in conjunction with
the driver airbag. During a frontal vehicle impact,
the knee blockers work in concert with properly fas-
tened and adjusted seat belts to restrain both the
driver and the front seat passenger in the proper
position for an airbag deployment. The knee blockers
also absorb and distribute the crash energy from the
driver and the front seat passenger to the structure
of the instrument panel. The seat belt tensioner
removes the slack from the driver side front seat belt
to provide further assurance that the driver is prop-
erly positioned and restrained for an airbag deploy-
ment.
8O - 4 RESTRAINTSKJ
RESTRAINTS (Continued)

The ACM housing also has an integral ground lug
with a tapped hole that protrudes from the lower left
rear corner of the unit. This lug provides a case
ground to the ACM when a ground screw is installed
through the left side of the mounting bracket. Two
molded plastic electrical connector receptacles exit
the right side of the ACM housing. The smaller of the
two receptacles contains twelve terminal pins, while
the larger one contains twenty-three. These terminal
pins connect the ACM to the vehicle electrical system
through two dedicated take outs and connectors of
the instrument panel wire harness.
A molded rubber protective cover is installed
loosely over the ACM to protect the unit from con-
densation or coolant leaking from a damaged or
faulty heater-air conditioner unit housing. An inte-
gral flange on the left side of the cover is secured to
the floor panel transmission tunnel with a short
piece of double-faced tape as an assembly aid during
the manufacturing process, but this tape does not
require replacement following service removal.
The impact sensor and safing sensor internal to
the ACM are calibrated for the specific vehicle, and
are only serviced as a unit with the ACM. The ACM
cannot be repaired or adjusted and, if damaged or
faulty, it must be replaced. The ACM cover is avail-
able for separate service replacement.
OPERATION
The microprocessor in the Airbag Control Module
(ACM) contains the front supplemental restraint sys-
tem logic circuits and controls all of the front supple-
mental restraint system components. The ACM uses
On-Board Diagnostics (OBD) and can communicate
with other electronic modules in the vehicle as well
as with the DRBIIItscan tool using the Programma-
ble Communications Interface (PCI) data bus net-
work. This method of communication is used for
control of the airbag indicator in the ElectroMechani-
cal Instrument Cluster (EMIC) and for supplemental
restraint system diagnosis and testing through the
16-way data link connector located on the driver side
lower edge of the instrument panel. (Refer to 8 -
ELECTRICAL/INSTRUMENT CLUSTER/AIRBAG
INDICATOR - OPERATION).
The ACM microprocessor continuously monitors all
of the front supplemental restraint system electrical
circuits to determine the system readiness. If the
ACM detects a monitored system fault, it sets an
active and stored Diagnostic Trouble Code (DTC) and
sends electronic messages to the EMIC over the PCI
data bus to turn on the airbag indicator. An active
fault only remains for the duration of the fault or in
some cases the duration of the current ignition
switch cycle, while a stored fault causes a DTC to be
stored in memory by the ACM. For some DTCs, if afault does not recur for a number of ignition cycles,
the ACM will automatically erase the stored DTC.
For other internal faults, the stored DTC is latched
forever.
On models equipped with optional side curtain air-
bags, the ACM communicates with both the left and
right Side Impact Airbag Control Modules (SIACM)
over the PCI data bus. The SIACM notifies the ACM
when it has detected a monitored system fault and
stored a DTC in memory for its respective side cur-
tain airbag system, and the ACM sets a DTC and
controls the airbag indicator operation accordingly.
The ACM also monitors a Hall effect-type seat belt
switch located in the buckle of each front seat belt to
determine whether the seatbelts are buckled, and
provides an input to the EMIC over the PCI data bus
to control the seatbelt indicator operation based upon
the status of the driver side front seat belt switch.
The ACM receives battery current through two cir-
cuits; a fused ignition switch output (run) circuit
through a fuse in the Junction Block (JB), and a
fused ignition switch output (run-start) circuit
through a second fuse in the JB. The ACM has a case
ground through a lug on the bottom of the ACM
housing that is secured with a ground screw to the
left side of the ACM mounting bracket. The ACM
also receives a power ground through a ground cir-
cuit and take out of the instrument panel wire har-
ness. This take out has a single eyelet terminal
connector that is secured by a second ground screw
to the left side of the ACM mounting bracket. These
connections allow the ACM to be operational when-
ever the ignition switch is in the Start or On posi-
tions. The ACM also contains an energy-storage
capacitor. When the ignition switch is in the Start or
On positions, this capacitor is continually being
charged with enough electrical energy to deploy the
airbags for up to one second following a battery dis-
connect or failure. The purpose of the capacitor is to
provide backup supplemental restraint system pro-
tection in case there is a loss of battery current sup-
ply to the ACM during an impact.
Two sensors are contained within the ACM, an
electronic impact sensor and a safing sensor. The
ACM also monitors inputs from two remote front
impact sensors located on the back of the right and
left vertical members of the radiator support near
the front of the vehicle. The electronic impact sensors
are accelerometers that sense the rate of vehicle
deceleration, which provides verification of the direc-
tion and severity of an impact. The safing sensor is
an electromechanical sensor within the ACM that
provides an additional logic input to the ACM micro-
processor. The safing sensor is a normally open
switch that is used to verify the need for an airbag
deployment by detecting impact energy of a lesser
8O - 10 RESTRAINTSKJ
AIRBAG CONTROL MODULE (Continued)

magnitude than that of the electronic impact sensors,
and must be closed in order for the airbags/seat belt
tensioner to deploy. A pre-programmed decision algo-
rithm in the ACM microprocessor determines when
the deceleration rate as signaled by the impact sen-
sors and the safing sensor indicate an impact that is
severe enough to require front supplemental
restraint system protection and, based upon the sta-
tus of the seatbelt switch inputs and the severity of
the monitored impact, determines what combination
of driver seat belt tensioner and/or front airbag
deployment is required for each front seating posi-
tion. When the programmed conditions are met, the
ACM sends the proper electrical signals to deploy the
driver seat belt tensioner and/or the multistage dual
front airbags at the programmed force levels.
The hard wired inputs and outputs for the ACM
may be diagnosed and tested using conventional
diagnostic tools and procedures. However, conven-
tional diagnostic methods will not prove conclusive in
the diagnosis of the ACM, the PCI data bus network,
or the electronic message inputs to and outputs from
the ACM. The most reliable, efficient, and accurate
means to diagnose the ACM, the PCI data bus net-
work, and the electronic message inputs to and out-
puts from the ACM requires the use of a DRBIIIt
scan tool. Refer to the appropriate diagnostic infor-
mation.

CHILD TETHER ANCHOR
DESCRIPTION
All vehicles are equipped with three, fixed-position,
child seat tether anchors (Fig. 9). Two anchors are
integral to the back of the right rear seat back panel,
and one is integral to the left rear seat back panel.
The child seat tether anchors cannot be adjusted or
repaired and, if faulty or damaged, they must be
replaced as a unit with the rear seat back panel.
OPERATION
See the owner's manual in the vehicle glove box for
more information on the proper use of the factory-in-
stalled child seat tether anchors.
CLOCKSPRING
DESCRIPTION
The clockspring assembly is secured with two inte-
gral plastic latches onto the upper steering column
housing near the top of the steering column behind
the steering wheel (Fig. 10). The clockspring consists
of a flat, round molded plastic case with a stubby tail
that hangs below the steering column and contains
two connector receptacles that face toward the
instrument panel (Fig. 11). Within the plastic hous-
ing is a spool-like molded plastic rotor with a large
exposed hub and several plastic rollers. The upper
surface of the rotor hub has a large center hole, a
release button, a clear plastic inspection window, two
short pigtail wires with connectors, and a connector
receptacle that faces toward the steering wheel. Two
versions of the clockspring are used on this model,
one is a seven circuit unit for vehicles not equipped
with optional remote radio switches on the steering
wheel and can be visually identified by the use of yel-
low heat-shrink tubing on the pigtail wires, while the
other is a nine circuit unit for vehicles with remote
radio switches and can be visually identified by the
use of black heat-shrink tubing on the pigtail wires.
A rubber bumper block is located on each side of
the tower formation that contains the connector
receptacle and pigtail wires on the upper surface of
the rotor hub. The lower surface of the rotor hub has

a molded plastic turn signal cancel cam with a single
lobe that is integral to the rotor. Within the plastic
case and wound around the rotor spool is a long rib-
bon-like tape that consists of several thin copper wire
leads sandwiched between two thin plastic mem-
branes. The outer end of the tape terminates at the
connector receptacles that face the instrument panel,
while the inner end of the tape terminates at the pig-
tail wires and connector receptacle on the hub of the
clockspring rotor that face the steering wheel.
Service replacement clocksprings are shipped pre-
centered and with a molded plastic shield that snaps
onto the rotor over the release button. The release
button secures the centered clockspring rotor to the
clockspring case and the shield prevents the release
button from being inadvertently depressed during
shipment and handling, but the shield must be
removed from the clockspring after it is installed on
the steering column. (Refer to 8 - ELECTRICAL/RE-
STRAINTS/CLOCKSPRING - STANDARD PROCE-
DURE - CLOCKSPRING CENTERING).
The clockspring cannot be repaired. If the clock-
spring is faulty, damaged, or if the driver airbag has
been deployed, the clockspring must be replaced.
OPERATION
The clockspring is a mechanical electrical circuit
component that is used to provide continuous electri-
cal continuity between the fixed instrument panel
wire harness and the electrical components mounted
on or in the rotating steering wheel. On this model
the rotating electrical components include the driver
airbag, the horn switch, the speed control switches,and the remote radio switches, if the vehicle is so
equipped. The clockspring case is positioned and
secured to the upper steering column housing near
the top of the steering column. The connector recep-
tacles on the tail of the fixed clockspring case connect
the clockspring to the vehicle electrical system
through two take outs with connectors from the
instrument panel wire harness. The clockspring rotor
is movable and is keyed by the tower formation that
is molded onto the upper surface of the rotor hub to
an opening that is cast into the steering wheel arma-
ture. Rubber bumper blocks on either side of the
clockspring tower formation eliminate contact noise
between the clockspring tower and the steering
wheel. The lobe of the turn signal cancel cam on the
lower surface of the clockspring rotor hub contacts a
turn signal cancel actuator of the multi-function
switch to provide automatic turn signal cancellation.
The yellow-sleeved pigtail wires on the upper surface
of the clockspring rotor connect the clockspring to the
driver airbag, while a steering wheel wire harness
connects the connector receptacle on the upper sur-
face of the clockspring rotor to the horn switch and,
if the vehicle is so equipped, to the optional speed
control switches and remote radio switches on the
steering wheel.
Like the clockspring in a timepiece, the clockspring
tape has travel limits and can be damaged by being
wound too tightly during full stop-to-stop steering
wheel rotation. To prevent this from occurring, the
clockspring is centered when it is installed on the
steering column. Centering the clockspring indexes
the clockspring tape to the movable steering compo-
nents so that the tape can operate within its
designed travel limits. However, if the clockspring is
removed from the steering column or if the steering
shaft is disconnected from the steering gear, the
clockspring spool can change position relative to the
movable steering components and must be re-cen-
tered following completion of the service or the tape
may be damaged. Service replacement clocksprings
are shipped pre-centered and with a plastic shield
installed over the clockspring release button. This
shield should not be removed and the release button
should not be depressed until the clockspring has
been installed on the steering column. If the release
button is depressed before the clockspring is installed
on a steering column, the clockspring centering pro-
cedure must be performed. (Refer to 8 - ELECTRI-
CAL/RESTRAINTS/CLOCKSPRING - STANDARD
PROCEDURE - CLOCKSPRING CENTERING).

CENTERING
The clockspring is designed to wind and unwind
when the steering wheel is rotated, but is only

designed to rotate the same number of turns (about
five complete rotations) as the steering wheel can be
turned from stop to stop. Centering the clockspring
indexes the clockspring tape to other steering compo-
nents so that it can operate within its designed
travel limits. The rotor of a centered clockspring can
be rotated two and one-half turns in either direction
from the centered position, without damaging the
clockspring tape.
However, if the clockspring is removed for service
or if the steering column is disconnected from the
steering gear, the clockspring tape can change posi-
tion relative to the other steering components. The
clockspring must then be re-centered following com-
pletion of such service or the clockspring tape may be
damaged. Service replacement clocksprings are
shipped pre-centered, with the release button
engaged (raised) and a molded plastic shield installed
over the release button. This release button should
not be disengaged and the shield should not be
removed until the clockspring has been installed on
the steering column. If the release button is disen-
gaged before the clockspring is installed on a steering
column, the clockspring centering procedure must be
performed.
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE SUPPLEMENTAL RESTRAINT
SYSTEM BEFORE ATTEMPTING ANY STEERING
WHEEL, STEERING COLUMN, DRIVER AIRBAG,
PASSENGER AIRBAG, SEAT BELT TENSIONER,
FRONT IMPACT SENSORS, SIDE CURTAIN AIRBAG,
OR INSTRUMENT PANEL COMPONENT DIAGNOSIS
OR SERVICE. DISCONNECT AND ISOLATE THE
BATTERY NEGATIVE (GROUND) CABLE, THEN
WAIT TWO MINUTES FOR THE SYSTEM CAPACI-
TOR TO DISCHARGE BEFORE PERFORMING FUR-
THER DIAGNOSIS OR SERVICE. THIS IS THE ONLY
SURE WAY TO DISABLE THE SUPPLEMENTAL
RESTRAINT SYSTEM. FAILURE TO TAKE THE
PROPER PRECAUTIONS COULD RESULT IN ACCI-
DENTAL AIRBAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.
NOTE: Before starting this procedure, be certain to
turn the steering wheel until the front wheels are in
the straight-ahead position.
(1) Place the front wheels in the straight-ahead
position.
(2) Remove the clockspring from the steering col-
umn. (Refer to 8 - ELECTRICAL/RESTRAINTS/
CLOCKSPRING - REMOVAL).
(3) Depress the release button (Fig. 12).(4) Keeping the release button depressed, rotate
the clockspring rotor clockwise to the end of its
travel.Do not apply excessive torque.
(5) From the end of the clockwise travel, rotate the
rotor about two and one-half turns counterclockwise,
then release the release button. The clockspring
tower formation with the pigtail wires for the driver
airbag and the connector receptacle for the steering
wheel wire harness should end up at the top, the
blue roller should be visible through the inspection
window, and the printed arrow on the label of the
clockspring rotor should be aligned with the arrow
molded into the clockspring case. The clockspring is
now centered.
(6) The front wheels should still be in the straight-
ahead position. Reinstall the clockspring onto the
steering column. (Refer to 8 - ELECTRICAL/RE-
STRAINTS/CLOCKSPRING - INSTALLATION).
REMOVAL
The clockspring cannot be repaired. It must be
replaced if faulty or damaged, or if the driver airbag
has been deployed.
