inspected every three years or 30,000 miles / 48,000
Km. To inspect system use Passive Restraint System
Diagnostic Procedures Manual. If the Air Bag Module Assembly is defective and
non-deployed, refer to Chrysler Motors current re-
turn list for proper handling procedures.
WARNING: REPLACE AIR BAG SYSTEM COMPO-
NENTS WITH CHRYSLER MOPAR TSPECIFIED RE-
PLACEMENT PARTS. SUBSTITUTE PARTS MAY
VISUALLY APPEAR INTERCHANGEABLE, BUT IN-
TERNAL DIFFERENCES MAY RESULT IN INFERIOR
OCCUPANT PROTECTION.
THE FASTENERS, SCREWS, AND BOLTS, ORIG-
INALLY USED FOR THE AIR BAG COMPO-
NENTS, HAVE SPECIAL COATINGS AND ARE
SPECIFICALLY DESIGNED FOR THE AIR BAG
SYSTEM. THEY MUST NEVER BE REPLACED
WITH ANY SUBSTITUTES. ANYTIME A NEW
FASTENER IS NEEDED, REPLACE WITH THE CORRECT FASTENERS PROVIDED IN THE SER-
VICE PACKAGE OR FASTENERS LISTED IN THE

GENERAL INFORMATION
AIR BAG MODULE
The air bag module is the most visible part of the
system (Fig 1). It contains the air bag cushion and
its supporting components. The air bag module con-
tains a housing to which the cushion and inflator are
attached and sealed.
The inflator assembly is mounted to the back of the
module housing. When supplied with the proper elec-
trical signal the inflator assembly will produce a gas
and discharges it directly into the cushion. A protec-
tive cover is fitted to the front of the air bag module
and forms a decorative cover in the center of the
steering wheel. The air bag module is mounted di-
rectly to the steering wheel.

FRONT IMPACT SENSORS
The driver air bag system is a safety device de-
signed to reduce the risk of fatality or serious injury,
caused by a frontal impact of the vehicle. The impact sensors provide verification of the di-
rection and severity of the impact. Three impact sen-
sors are used. One is called a safing sensor. It is
located inside the diagnostic module which is
mounted on the floor pan, just forward of the center
console. The other two sensors are mounted on the
upper crossmember of the radiator closure panel on
the left and right side of the vehicle under the hood. The impact sensors are threshold sensitive switches
that complete an electrical circuit when an impact
provides a sufficient G force to close the switch. The
sensors are calibrated for the specific vehicle and re-
act to the severity and direction of the impact.
CLOCKSPRING
The clockspring is mounted on the steering column
behind the steering wheel, and is used to maintain a
continuous electrical circuit between the wiring har-
ness and the driver's air bag module. This assembly
consists of a flat ribbon-like electrically conductive
tape which winds and unwinds with the steering
wheel rotation.
DIAGNOSTIC MODULE
The Air Bag System Diagnostic Module (ASDM)
contains the safing sensor and energy reserve capac-
itor. The ASDM monitors the system to determine
the system readiness. The ASDM will store sufficient
energy to deploy the air bag for only two minutes af-
ter the battery is disconnected. If both front impact
sensors are open the air bag could be deployed up to
9.5 minutes after the battery is disconnected. The
ASDM contains on-board diagnostics, and will illumi-
nate the AIR BAG warning lamp in the cluster when
a fault occurs.
STORAGE
The air bag module must be stored in its original
special container until used for service. Additionally,
it must be stored in a clean, dry environment, away
from sources of extreme heat, sparks, and sources of
high electrical energy. Always place or store the
module on a surface with the trim cover facing up to
minimize movement in case of accidental deploy-
ment.
HANDLING LIVE MODULE
At no time should any source of electricity be per-
mitted near the inflator on the back of the module.
When carrying a live module, the trim cover should
be pointed away from the body to minimize injury in
the event of accidental deployment. In addition, if
the module is placed on a bench or other surface, the plastic trim cover should be face up to minimize
movement in case of accidental deployment. When handling a steering column with an air bag
module attached, never place the column on the floor
or other surface with the steering wheel or module
face down.
DEPLOYED MODULE
The vehicle interior may contain a very small
amount of sodium hydroxide powder, a byproduct of
air bag deployment. Since this powder can irritate
the skin, eyes, nose or throat, be sure to wear safety
glasses, rubber gloves and long sleeves during
cleanup (Fig. 2).
If you find that the cleanup is irritating your skin,
run cool water over the affected area. Also, if you ex-
perience nasal or throat irritation, exit the vehicle
for fresh air until the irritation ceases. If irritation
continues, see a physician.
CLEANUP PROCEDURE
Begin the cleanup by putting tape over the two air
bag exhaust vents (Fig. 3) so that no additional pow-
der will find its way into the vehicle interior. Then
remove the air bag and air bag module from the ve-
hicle. Use a vacuum cleaner to remove any residual pow-
der from the vehicle interior. Work from the outside
in so that you avoid kneeling or sitting in a un-
cleaned area. Be sure to vacuum the heater and A/C outlets as
well (Fig. 4). In fact it's a good idea to run the blower
on low and to vacuum up any powder expelled from
the plenum. You may need to vacuum the interior of
the car a second time to recover all of the powder. Place the deployed bag and module in your auto-
motive scrap.

SERVICE OF DEPLOYED AIR BAG MODULE
After an air bag has been deployed, the air bag
module and clockspring must be replaced because
they cannot be reused. Other air bag system compo-
nents are replaced if damaged.
SCHEDULED MAINTENANCE INSPECTION
Vehicles equipped with a Air Bag System must be
inspected every three years or 30,000 miles / 48,000
Km. The following items should be inspected. (1) Inspect components for damage or deteriora-
tion. (a) If the air bag module housing shows signs of
physical damage or abuse, replace the module. (b) Check that both front impact sensors are
properly installed to the upper crossmember of the
radiator closure panel. Repair as required.
(2) Check the air bag warning lamp for proper op-
eration as follows: (a) Turn ignition switch to the ON position, the
air bag warning lamp should light. If not, test the system using the DRB II and Passive Restraint
System Diagnostic Procedures Manual. Repair as
required.
(b) The air bag warning lamp lights, but fails to go
out after ten seconds. Test the system using the DRB
II and Passive Restraint System Diagnostic Proce-
dures Manual. Repair as required. (c) Erasing of fault codes is not required.

connect the negative battery cable. (6) Using the DRB II, read and record active fault
data. (7) Read and record any stored faults.
(8) Refer to the Passive Restraint Diagnostic Test
Manual if any faults are found in steps 6 and 7. (9) Erase stored faults if there are no active fault
codes. If problems remain, fault codes will not erase. (10) With the ignition key in the ON position, make
sure no one is in the vehicle. (11) From the passenger side of vehicle, turn the
ignition key to OFF then ON and observe the instru-
ment cluster air bag lamp. It should go on for 6 to 8
seconds, then go out; indicating system is functioning
normally. If air bag warning lamp either fails to light,
blinks on and off or goes on and stays on, there is
a system malfunction. Refer to the Passive Re-
straint Diagnostic Test Manual to diagnose the
problem.

Bench checking of the relay may be accomplished
in the following manner. By following the in-vehicle
procedure except Step 2: With a DC power supply,
apply 12 volts to terminal B and I and ground termi-
nal G.
REPAIR GRID LINES, TERMINALS AND PIGTAILS
The repair of the grid lines or the terminal is pos-
sible using the Mopar Repair Package or equivalent. (1) Mask repair area so conductive epoxy can be
extended onto the line or the bus bar (Fig. 5).
(2) Follow instructions in repair kit for preparing
damaged area. (3) Remove package separator clamp and mix plastic
conductive epoxy thoroughly. Fold in half and cut
center corner to dispense epoxy. (4) For grid line, mark off area to be repaired with
masking tape or a template (Fig. 5). (5) Apply conductive epoxy through slit in masking
tape. Overlap both ends of the break by 19mm (3/4
inch). (6) For a terminal or pigtail replacement, mask
adjacent areas so epoxy can be extended onto line as
well as bus bar. Apply a thin layer of epoxy to area
where terminal was fastened and to adjacent line. (7) Apply a thin layer of conductive epoxy on termi-
nal and place terminal on desired location. To prevent
terminal from moving while the epoxy is curing, it
must be wedged or clamped. (8) Carefully remove masking tape from grid line.
CAUTION: Do not allow the glass surface to exceed
204ÉC (400ÉF), glass may fracture. (9) Allow epoxy to cure 24 hours at room tempera-
ture or use heat gun with a 260É-371ÉC (500É-700ÉF)
range for 15 minutes. Hold gun approximately 254 mm
(10 inches) from repaired area. (10) After conductive epoxy is properly cured remove
wedge from terminal and check out operation of rear
window defogger. Do not attach connectors until curing
is complete.

(4) Reverse battery leads (steps 1 and 2 above) and
window should now move. If window does not move,
remove motor. See below for motor removal from ve-
hicle. (5) If window moved completely up or down, motor
should be reversed one more time (reverse leads from
step 4) to complete a full window travel inspection.
GEAR AND PINION REPLACEMENT AND
LUBRICATION
The window glass and mechanism have been found
to move freely. The window motor works. But the
glass does not move up or down. The motor gear and
pinion will need to be replaced (Fig. 1).
When gear and pinion assembly is replaced in gear
box, lubrication of gear box, gear pinion and seal is
necessary. In the event there is no lubricant in gear box, fill
with MOPAR multi-mileage lubricant or equivalent.
Apply a liberal amount of lubricant to inside area of
seal marked A as illustrated in Fig. 1 and sealing
surface at center area of gear and pinion coupling.
Also lubricate center gear box shaft and worm gear.
MOTOR REPLACEMENT CONVENTIONAL
REGULATORS
The following procedure describes replacement of a
defective motor without removing window regulator
or detaching any window system components. This
method of motor replacement is not acceptable if any
of window system parts are loosened or removed from
door such as:
² Lift channels
² Up stops
² Tracks and pivot brackets
² Are already loose by deficiency
² Are to be loosened or removed from the door.
Then use method of repair where entire regulator
is removed from door (Fig. 2 through 9).
REMOVAL
(1) Raise window to full UP position and keep it
there at all times while replacing motor. If window is in
any position other than full UP and motor is separated
from spring loaded regulator, then regulator counterbal-
ance spring will tend to propel window upwards.
WARNING:PLACE A WINDOW BLOCK IN DOOR
THAT WILL POSITIVELY PREVENT WINDOW FROM
GOING DOWN. THIS ACTION WILL PREVENT IN-
JURY THAT COULD BE CAUSED BY INCORRECT
INSTALLATION OF COUNTERBALANCE SPRING
OR UPWARD MOVEMENT OF THE WINDOW.
(2) Disconnect wiring connector from motor which
is located about eleven inches from motor. (3) Remove three mounting screws that hold motor
gearbox to regulator. Remove third screw that se-
cures motor tie-down bracket to inner panel if so
equipped. There are three holes in inner panel which
provide access to three mounting screws that secure
gearbox to regulator (Fig. 2).
