GENERAL INFORMATION
Following are general descriptions of the major
components in the XJ (Cherokee)/YJ (Wrangler)
model turn signal and hazard warning systems. Refer
to Group 8W - Wiring Diagrams for complete circuit
descriptions and diagrams.
TURN SIGNAL SYSTEM
With the ignition switch in the ON or ACCESSORY
position and the turn signal switch lever (YJ) or
multi-function switch control lever (XJ) moved up
(right turn) or down (left turn), the turn signal sys-
tem is activated.
When the turn signal system is activated, the se-
lected (right or left) turn signal indicator lamp, front
park/turn signal lamp and rear tail/stop/turn signal
lamp bulb filaments will flash. With the headlamp
switch in the OFF position, the turn and front side
marker lamps flash in unison. With the headlamp
switch in the ON position, the turn and front side
marker lamps flash alternately.
HAZARD WARNING SYSTEM
The hazard warning is activated by a switch button
located below the ignition lock cylinder (YJ) or on the
top of the steering column (XJ) between the steering
wheel and the instrument panel. The hazard warning
flasher (YJ) or combination flasher (XJ) receives bat-
tery feed at all times, and the system is functional
regardless of ignition switch position. The hazard
warning switch button is identified with a double
triangle. On YJ models, push the switch button in to
activate the hazard warning system and pull the
button out to turn system off. On XJ models, push in
on the switch button to latch the switch and activate
the hazard warning system, and push in on the
switch button again to unlatch the switch and turn
the system off.
When the hazard warning system is activated, all
(right and left) turn signal indicator, front park/turn
signal lamp and rear tail/stop/turn signal lamp bulb
filaments will flash.
TURN SIGNAL FLASHER (YJ ONLY)
The turn signal flasher is located in the fuseblock
module. It contains one fixed contact point and one
contact point attached to a flexible bimetal arm. The
contact points are normally closed. When a turn sig-
nal is activated, current flows through the flasher. As
current flows through the bimetal arm it heats and
flexes to pull the contact points open, stopping cur-
rent flow. As the bimetal arm cools it straightens,
until the contact points close and the cycle repeats.
The standard flasher is designed to handle the cur-
rent flow requirements of the factory installed light-
ing. If supplemental lighting is added to the turn
signal circuits such as when towing a trailer with
lights, the current flow through the flasher increases.
This causes the flash rate to increase. It is recom-
mended that the standard flasher be replaced with a
heavy-duty (hazard warning) flasher when supple-
mental lighting is added.
However, when a turn signal bulb fails with a stan-
dard flasher, the remaining bulbs in that circuit will
light, but not flash. This will give the driver an indi-
cation to check the turn signal bulbs. Because a
heavy-duty flasher has different internal circuitry, a
failed bulb will not prevent the remaining bulbs in
the circuit from flashing. Therefore, it is recom-
mended that an occasional visual inspection of exte-
rior turn signal lamp operation be performed when a
heavy-duty flasher is installed.
HAZARD WARNING FLASHER (YJ ONLY)
The hazard warning flasher is located in the fuse-
block module. The hazard warning flasher contains
two normally open contact points mounted to two
flexible arms. A bimetal strip is attached between the
two arms. When the hazard warning is activated,
current flows through the flasher. As the current
flows through the bimetal strip it heats and pulls the
flexible arms together until the contact points close,

DIAGNOSIS
When diagnosing the turn signal or hazard warning
circuits, remember that high generator output can
burn out bulbs rapidly and repeatedly. If this is a
problem on the vehicle being diagnosed, refer to
Group 8A - Battery/Starting/Charging Systems Diag-
nostics to test charging system.

SIBLE PERSONAL INJURY.
TURN SIGNAL/HAZARD WARNING SYSTEM - XJ
(1) Turn ignition switch to ON position. Actuate the
turn signal lever or hazard warning button. Observe
the turn indicator lamp(s) in the instrument cluster.
If the flash rate is very high, check for a turn signal
bulb that is not lit. Replace that bulb or repair cir-
cuits to that lamp, as required. Test operation. If turn
indicator does not light, continue to next step.
(2) Remove and inspect fuse 8 (turn signals) in
fuseblock module, or fuse F13 (hazard warning) in the
Power Distribution Center. Replace fuse, if required.
(3) Remove combination flasher from relay center
and replace with a known good unit. Test operation of
turn signal and hazard warning systems. If OK, re-place faulty combination flasher. If not OK, remove
test flasher and go to next step.
(4) With ignition switch in ON position, check for
battery voltage at cavity for flasher terminal J1 (Fig.
2). If OK, go to next step. If not OK, repair circuit to
ignition switch as required.
(5) With ignition switch in OFF position, check for
battery voltage at cavity for flasher terminal J2. If
OK, go to next step. If not OK, repair circuit to Power
Distribution Center as required.
(6) With ignition switch in OFF position, check for
continuity between cavity for flasher terminal J5 and
a good ground. There should be continuity. If OK, go
to next step. If not OK, repair circuit to ground as
required.
(7) Locate the multi-function switch connector. See
Multi-Function Switch, in this group. Check for conti-
nuity between cavity for flasher terminal J3 and cav-
ity 13 of the multi-function switch connector. There
should be continuity. If OK, go to next step. If not OK,
repair open circuit as required.
(8) Check for continuity between cavity for flasher
terminal J4 and cavity 17 of the multi-function switch
connector. There should be continuity. If OK, test
multi-function switch. If not OK, repair open circuit
as required.
TURN SIGNAL SYSTEM - YJ
A turn signal indicator lamp that remains lit (with-
out flashing) is an indication of a burned out exterior
turn signal bulb or faulty exterior lamp circuit. Check

GENERAL INFORMATION - XJ
Following are general descriptions of the major
components in the XJ (Cherokee) wiper and washer
systems. Refer to Group 8W - Wiring Diagrams for
complete circuit descriptions and diagrams.
WINDSHIELD WIPER SYSTEM
A two-speed wiper system is standard equipment
on all left-hand drive XJ models. An optional inter-
mittent wipe system is available. The intermittent
wipe system is standard equipment on all right-hand
drive XJ models. The two-speed wiper system allows
the driver to select from two wiper speeds. The inter-
mittent wipe system allows the driver to select from
two wiper speeds or an intermittent wipe feature
that allows a delay between wipes of 2 to 15 seconds.
Refer to the owner's manual for more information on
wiper system controls and operation.
The wipers will operate only when the ignition
switch is in the ACCESSORY or ON position. A cir-
cuit breaker near the fuseblock module protects the
circuitry of the wiper system on left-hand drive mod-
els. The circuit breaker is in the fuseblock module on
right-hand drive models.
WINDSHIELD WASHER SYSTEM
A electrically-operated windshield washer system is
standard equipment on all XJ models. The washers will
operate only when the ignition switch is in the ACCES-
SORY or ON position. A circuit breaker near the fuse-
block module protects the circuitry of the washer
system. Refer to the owner's manual for more informa-
tion on washer system controls and operation.
LIFTGATE WIPER/WASHER SYSTEM
A liftgate wiper/washer system is an available op-
tion on XJ models. The liftgate wiper is a fixed cycle
intermittent wipe system. A single switch on the in-
strument panel controls both the liftgate wiper and
washer functions. These systems will operate only
when the ignition switch is in the ON position. Fuse
1 in the fuseblock module protects the circuitry ofboth the liftgate wiper and washer. Refer to the own-
er's manual for more information on liftgate wiper/
washer system controls and operation.
WIPER ARMS, BLADES, AND ELEMENTS
All XJ models have two 18-inch windshield wiper
blades with replaceable rubber elements (squeegees).
Models with the liftgate wiper option use a single 12-
inch wiper blade with a replaceable rubber element
(squeegee).
Caution should be exercised to protect the rubber
squeegees from any petroleum-based cleaners or con-
taminants, which will rapidly deteriorate the squee-
gee rubber. If squeegees are damaged, worn or
contaminated they must be replaced.
Wiper squeegees exposed to the weather for a long
time tend to lose their wiping effectiveness. Periodic
cleaning of the squeegees is suggested to remove de-
posits of salt and road film. The wiper blades, arms
and windshield or liftgate glass should be cleaned
with a sponge or cloth and a mild detergent or non-
abrasive cleaner. If the squeegees continue to streak
or smear, they should be replaced.
The blades are mounted to spring-loaded wiper
arms. Spring tension of the wiper arms controls the
pressure applied to the blades on the glass. The
windshield wiper arms are attached by an integral
latch to the two wiper pivots on the cowl grille panel
at the base of the windshield. The liftgate wiper arm
is attached by an integral latch directly to the lift-
gate wiper motor output shaft on the liftgate panel.
The wiper arms and blades can not be adjusted or re-
paired. If faulty, they must be replaced.
WIPER LINKAGE AND PIVOTS
The wiper pivots are fastened to the cowl top panel
with screws beneath the cowl cover/grille panel. Each
pivot assembly can be replaced by removing the cowl
grille panel, unsnapping the linkage bushing(s) from
the pivot crank arm pins, and removing the mount-
ing screws.
