DOME/COURTESY LAMP SERVICE
INFORMATIONÐYJ
The dome/cargo and underpanel courtesy lamps are
controlled via ON/OFF switches. The ON/OFF
switches are in the lamp ground circuits. Voltage via
the dome/courtesy lamp fuse is applied directly to the
lamp bulbs. When either door is opened, the door pil-
lar switch contacts close and provide a direct path to
vehicle body ground.
The dome/cargo and underpanel courtesy lamps
can also be turned on via the interior lamp illumina-
tion rheostat.

GENERAL INFORMATION
The airbag system is a standard equipment safety
device on XJ (Cherokee) models. It is designed to pro-
tect the driver from serious injury, caused by a fron-
tal impact of the vehicle. If the airbag module
assembly is defective and non-deployed, refer to
Chrysler Corporation current return list for proper
handling procedures.
Following are general descriptions of the major
components in the airbag system.AIRBAG MODULE
The airbag module protective cover is the only vis-
ible part of the system. The module is mounted di-
rectly to the steering wheel. Under the airbag
module cover, the airbag cushion and its supporting
components are contained. The airbag module con-
tains a housing to which the cushion and impact sen-
sor/inflator assembly are attached and sealed. The
airbag module is non-serviceable, and must be re-
placed if deployed or damaged in any way.
The impact sensor/inflator assembly is mounted to
the back of the module. The inflator seals the hole in
JRESTRAINT SYSTEMS 8M - 1

Page 494 of 2158

the airbag cushion so it can discharge the gas it pro-
duces directly into the cushion. The protective cover
is fitted to the front of the airbag module and forms
a decorative cover in the center of the steering wheel.
Upon airbag deployment, this cover will split hori-
zontally.
STORAGE
The airbag module must be stored in its original,
special container until used for service. Also, it must
be stored in a clean, dry environment; away from
sources of extreme heat, sparks, and 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 deployment.
IMPACT SENSOR/INFLATOR ASSEMBLY
The impact sensor/inflator assembly is mounted to
the back of the airbag module. It seals the hole in
the steering wheel side of the airbag cushion so that
gas produced in the inflator can be discharged di-
rectly into the cushion.
The impact sensor provides verification of the di-
rection and severity of the impact. A spherical sens-
ing mass housed in a cylinder will move forward and
rotate a D-shaft when the vehicle is subjected to a
frontal impact of sufficient severity. Airbag inflation
is designed to occur at a precisely calibrated vehicle
deceleration force, and is not linked to vehicle road
speed.The D-shaft retains two spring-loaded firing pins.
When a firing pin is released by the D-shaft, it
strikes and ignites a primer. The primer then reacts
with the pelletized, solid generant contained in the
inflator to produce the nitrogen gas that inflates the
airbag cushion.
ARMING/DISARMING MECHANISM
The steering wheel hub incorporates an airbag
arming/disarming mechanism and a specially de-
signed nut-blocker. The nut-blocker serves as a safety
to prevent removal of the airbag module until the
unit has been disarmed. A removable plastic cover
plug on the top, outer hub of the steering wheel al-
lows access to the arming screw.
When the airbag module is disarmed, the arming
screw extends upward from the steering wheel hub.
This will prevent installation of the plastic cover
plug. Also, the nut-blocker is retracted to allow ac-
cess to the two upper airbag module mounting nuts.
When the airbag module is armed, the plastic cover
plug will install flush with the outer surface of the
steering wheel hub. In addition, the nut-blocker will
prevent access to the two upper airbag module
mounting nuts.
DIAGNOSIS
This mechanical airbag system can not be diag-
nosed or repaired. The only serviced component is
the airbag module assembly. If the airbag module isdamaged in any way or deployed, it must be re-
placed.
SERVICE PROCEDURES
AIRBAG SYSTEM SERVICE (DEPLOYED)
Any vehicle which is to be returned to use after an
airbag deployment, must have the airbag module re-
placed. This is a one-time component and cannot be
reused.
AIRBAG MODULE HANDLING
UNDEPLOYED
At no time should any source of electricity be per-
mitted near the inflator on the back of the module.
When carrying an undeployed module, the trim cover
should be pointed away from the body to minimizeinjury in the event of accidental deployment. 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.
In addition, the airbag module should be disarmed
whenever the steering wheel or steering column re-
quires service or removal. Failure to observe this
warning could result in accidental airbag deployment
and possible personal injury. Refer to Group 19 -
Steering for more service procedures on steering
wheel and steering column.
8M - 2 RESTRAINT SYSTEMSJ

Page 495 of 2158

DEPLOYED
Following an airbag deployment, the vehicle inte-
rior will contain a powdery residue. This residue is
primarily sodium bicarbonate (baking soda), used as
an airbag cushion lubricant. However, there will also
be traces of sodium hydroxide powder, a chemical
byproduct of the generant used for airbag deploy-
ment. Since this powder can irritate the skin, eyes,
nose or throat, be sure to wear safety glasses, rubber
gloves and a long-sleeved shirt during cleanup (Fig.
1).
If you experience skin irritation during
cleanup, run cool water over the affected area.
Also, if you experience irritation of the nose or
throat, exit the vehicle for fresh air until the ir-
ritation ceases. If irritation continues, see a
physician.
CLEANUP PROCEDURE
Remove the airbag and airbag module from the ve-
hicle. Use a vacuum cleaner to remove any residual
powder from the vehicle interior. Clean from outside
the vehicle and work your way inside, so that you
avoid kneeling or sitting on an uncleaned area.
Be sure to vacuum the heater and A/C outlets as
well (Fig. 2). Run the blower on low and vacuum any
powder expelled from the plenum. You may need to
vacuum the interior of the car a second time to re-
cover all of the powder.
Place the deployed airbag and module in your ve-
hicular scrap pile.
AIRBAG MODULE REMOVE/INSTALL
WARNING: THIS AIRBAG SYSTEM IS A SENSITIVE,
COMPLEX MECHANICAL UNIT. BEFORE ATTEMPT-ING TO REMOVE OR INSTALL THE AIRBAG SYS-
TEM OR RELATED STEERING WHEEL AND
STEERING COLUMN COMPONENTS YOU MUST
FIRST DISARM THE AIRBAG FIRING MECHANISM.
FAILURE TO DO SO COULD RESULT IN ACCIDEN-
TAL DEPLOYMENT AND POSSIBLE PERSONAL IN-
JURY.
When removing a deployed airbag module,
rubber gloves, eye protection and long-sleeved
shirt should be worn. There may be deposits on
the airbag module and other interior surfaces,
which can cause irritation to the skin and eyes
in large doses.
(1) Disconnect battery negative cable and isolate.
(2) Using a small screwdriver, remove plastic cover
plug from top outer surface of steering wheel hub.
Exit vehicle and disarm airbag by reaching through
driver's side window and turning arming screw
counter-clockwise to its travel limit. When the screw
has reached its travel limit it will extend 1 inch
above the outer surface of the steering wheel hub
cover. This is done using an 8mm socket and manual
drive. DO NOT USE POWER-DRIVEN TOOLS.
(3) From back side of steering wheel, remove 4
nuts attaching airbag module to steering wheel (Fig.
3). This is done using a 10mm socket and manual
drive. DO NOT USE POWER-DRIVEN TOOLS.
(4) Remove airbag module from steering wheel.
(5) Reverse removal procedures to install. Tighten
airbag module attaching nuts to 9 to 11 Nzm (80 to
100 in. lbs.). Exit vehicle and arm airbag by reaching
through driver's side window and turning arming
screw clockwise to its travel limit. Arming screw
torque should not exceed 1.1 to 1.7 Nzm (10-15 in.
lbs.). Reinstall plastic cover plug in steering wheel
hub.

DIAGNOSIS............................. 1
GENERAL INFORMATION.................. 1SERVICE PROCEDURES................... 3
GENERAL INFORMATION
The electrically-heated rear window defogger is an
available option on XJ (Cherokee), and YJ (Wrangler)
models equipped with the hardtop roof option. Fol-
lowing are general descriptions of the major compo-
nents in the rear window defogger system. Refer to
Group 8W - Wiring Diagrams for complete circuit de-
scriptions and diagrams.
REAR WINDOW GLASS GRID
The heated rear window glass has two electrically-
conductive vertical bus bars and a series of horizon-
tal grid lines made of a silver-ceramic material,
which is baked on and bonded to the inside surface of
the glass. The grid lines and bus bars comprise a
parallel electrical circuit.
When the rear window defogger switch is placed in
the ON position, current is directed to the rear win-
dow grid lines through the bus bars. The grid lines
heat the rear window to clear the surface of fog or
snow. Circuit protection for the heated grid circuit is
provided by fuse 18 (XJ) or fuse 6 (YJ) in the fuse-
block module.
The grid lines and bus bars are highly resistant to
abrasion. However, it is possible for an open to occur
in an individual grid line resulting in no current flow
through the line. The grid lines can be damaged or
scraped off with sharp instruments. Care should be
taken in cleaning the glass or removing foreign ma-
terials, decals or stickers. Normal glass cleaning sol-
vents or hot water used with rags or toweling is
recommended.A repair kit is available to repair the grid lines and
bus bars, or to reinstall the heated glass pigtail
wires.
DEFOGGER SWITCH
The rear window defogger switch is mounted in the
instrument panel left of the steering column for XJ,
or right of the steering column for YJ. The switch cir-
cuit is protected by fuse 8 (XJ) or fuse 9 (YJ) in the
fuseblock module. Actuating the switch energizes the
relay and electronic timer. A light-emitting diode
(LED) in the switch (XJ), or a indicator lamp in the
switch (YJ), illuminates to indicate when the system
is turned on. The defogger switch can not be re-
paired. If faulty, the switch must be replaced.
DEFOGGER RELAY/TIMER
The defogger relay/timer is located in the relay cen-
ter on XJ models, or taped to the instrument panel
wiring harness behind the parking brake pedal in the
left cowl side area on YJ models. When the rear de-
fogger switch is actuated, the rear defogger relay is
energized. This causes current to flow through the
grid circuit for approximately 10 minutes, or until
the rear window defogger switch or ignition switch
are turned off.
DIAGNOSIS
SYSTEM TESTS
Electrically-heated rear window defogger operation
can be confirmed in the following manner:
(1) Turn the ignition switch to the ON position.
(2) Turn rear window defogger control switch ON.
(3) Monitor vehicle voltmeter. With the control
switch ON, a distinct needle deflection should be
noted.(4) The rear window defogger operation can be
checked by feeling the glass. A distinct difference in
temperature between the grid lines and adjacent
clear glass can be detected within 3 to 4 minutes of
operation.
(5) Using a DC voltmeter, contact terminal A (Fig.
1) (passenger side) with the negative lead, and termi-
JREAR WINDOW DEFOGGER 8N - 1

Page 498 of 2158

nal B (driver side) with the positive lead. The volt-
meter should read 10-14 volts.
Steps 3, 4 or 5 above will confirm system operation.
Indicator light illumination means that there is
power available at the output of the switch, but does
not confirm that power is reaching the rear window
grid lines.
If the rear window defogger does not operate, the
problem should be isolated in the following manner:
(1) Confirm that ignition switch is in ON position.
(2) Ensure that the heated rear window feed and
ground wires are connected to the glass. Confirm
that the ground wire has continuity to ground.
(3) Check fuses 8 and 18 (XJ), or fuses 6 and 9
(YJ) in fuseblock module. Fuses must be tight in
their receptacles and all electrical connections must
be secure.
When the above steps have been completed and the
system is still inoperative, one or more of the follow-
ing is faulty:
²defogger switch²relay/timer
²rear window grid lines (all grid lines would have
to be broken or one of the feed wires disconnected for
the entire system to be inoperative).
If turning the switch ON produces severe voltmeter
deflection, check for a short circuit.
REAR WINDOW GLASS GRID
To detect breaks in grid lines, the following proce-
dure is required:
(1) Turn ignition switch to the ON position. Turn
rear defogger switch ON. The indicator lamp should
light.
(2) Using a 12-volt DC voltmeter, contact vertical
bus bar on passenger side of vehicle (point A of Fig.
1) with negative lead of voltmeter. With positive lead
of voltmeter, contact vertical bus bar on driver side of
vehicle (point B of Fig. 1). The voltmeter should read
10-14 volts.
(3) With negative lead of voltmeter, contact a good
body ground point. The voltage reading should not
change. A different reading indicates a poor ground
connection.
(4) Connect negative lead of voltmeter to point A
on passenger side bus bar and touch each grid line at
mid-point with positive lead. A reading of approxi-
mately 6 volts indicates a line is good. A reading of
zero volts indicates a break in the grid line between
mid-point C and point B. A reading of 10-14 volts in-
dicates a break between mid-point C and point A.
Move toward break and voltage will change as soon
as break is crossed.

The meter should read battery voltage. If OK, go to
next step. If not OK, repair open from fuse 8 (XJ), or
fuse 6 (YJ).
(3) Measure resistance between relay connector
terminal 1 and left side (driver's side) of defogger
grid. The meter should read zero ohms. If OK, go to
next step. If not OK, repair open between relay con-
nector and left side of defogger grid.
(4) Measure resistance between relay connector
terminal 2 and a clean chassis ground. The meter
should read zero ohms. If OK, go to next step. If not
OK, repair open between relay connector and ground.
(5) Connect relay connector and measure voltage
at terminal 3. The meter should read approximately
5 volts. If not OK, replace defogger relay.
