1995 JEEP CHEROKEE steering

The liftgate wiper motor can not be repaired. If
faulty, the entire assembly must be replaced.
WINDSHIELD WIPER/WASHER SWITCH
Controls for the windshield wiper and washer sys-
tems are contained in the turn signal switch lever.
The turn signal switch lever is mounted on the left
side of the steering column between the steering
wheel and the instrument panel. The wiper/washer
switch can not be repaired. If any function of the
switch is faulty, the entire switch must be replaced.
LIFTGATE WIPER/WASHER SWITCH
The single two-function switch on the instrument
panel right of the steering column controls the lift-
gate wiper and washer functions. The rocker-type
switch features a detent in the WIPE position, but
only momentary contact in the WASH position. Both
the liftgate wiper and liftgate washer motors will op-
erate continuously for as long as the switch is held in
the WASH position. The switch can not be repaired;
if faulty, it must be replaced.
INTERMITTENT WIPE MODULE
In addition to low and high speed, the optional in-
termittent wipe system has a delay mode. The delay
mode has a range of 2 to 15 seconds. The length of
the delay is selected with a variable resistor in the
wiper switch and is accomplished by electronic cir-
cuitry within the intermittent wipe module. If the
washer knob is depressed while the wiper switch is
in the OFF position, the intermittent wipe module
will operate the wiper motor for approximately 2
wipes and automatically turn the motor off.
The intermittent wipe module is mounted to a
bracket behind the lower instrument panel, near the
steering column with a hook and loop fastener patch.
The module can not be repaired.
WINDSHIELD WASHER NOZZLES
The two fluidic washer nozzles are screwed into
openings in the cowl panel below the windshield and
are not adjustable. Washer fluid is fed to the nozzles
through hoses underneath the cowl panel. The noz-
zles can not be repaired and, if faulty, should be re-
placed.
LIFTGATE WASHER NOZZLE
The single liftgate washer nozzle is installed
through the liftgate glass and secured with a nut on
the inside of the glass. Washer fluid is fed to the noz-
zle from the washer reservoir in the engine compart-
ment. A liftgate washer hose system is routed
through the body of the vehicle with the body wiring
harness from the reservoir to the liftgate. The nozzle
can not be repaired and, if faulty, should be replaced.
WASHER RESERVOIR
The washer solvent reservoir is mounted with a
bracket to the left front inner fender shield near the
cowl panel. The same reservoir is used for both the
standard front and optional liftgate washer systems.
The reservoir and filler cap are available for service.
WASHER PUMPS
The washer pump and motor are press-fit into a
rubber grommet near the bottom of the washer res-
ervoir. Vehicles with the optional liftgate wiper/
washer system have two pumps installed in the
single reservoir. A permanently lubricated and sealed
motor is coupled to a rotor-type pump. Washer fluid
is gravity fed from the reservoir to the pump. The
pump then pressurizes the fluid and forces it through
the plumbing to the nozzles when the motor is ener-
gized. The pump and motor can not be repaired. If
faulty, the entire assembly must be replaced.

DIAGNOSIS - YJ
WINDSHIELD WIPER SYSTEM
(1) Remove circuit breaker from fuseblock module
and turn ignition switch to ACCESSORY or ON.
(a) Measure voltage at battery side of circuit
breaker cavity. Meter should read battery voltage.
If not OK, repair wiring from ignition switch.
(b) Measure resistance across circuit breaker ter-
minals. Meter should read zero ohms. If not OK,
replace failed circuit breaker.
(2) Unplug wiper motor side of wiring harness con-
nector (gray) from wiper switch side of wiring har-
ness connector (black), or from intermittent wipe
module (if equipped) at base of steering column. Turn
ignition switch to ACCESSORY or ON.
(a) Measure voltage at unplugged wiper motor
side of wiring harness connector (gray) terminal D.
Meter should read battery voltage. If not OK, re-
pair wiring from circuit breaker.
(b) Turn ignition switch to OFF and measure re-
sistance from unplugged wiper motor side of wiring
harness connector (gray) terminal G to ground.
Meter should read zero ohms. If not OK, repair
wiring to ground.
(3) Leave ignition switch in OFF, and back probe
wiring harness connector at wiper motor. Measure re-
sistance from terminal E of wiper motor side of con-
nector to ground. Meter should read zero ohms. If not
OK, repair wiring to ground.
(4) If equipped with intermittent wipe, turn igni-
tion switch to ACCESSORY or ON. Turn wiper
switch to LOW or HIGH. Unplug wiper switch side of
wiring harness connector (black) from intermittent
wipe module. Then plug both connectors that have
been removed from intermittent wipe module into
each other.
CAUTION: DO NOT move the wiper switch to DE-
LAY with the intermittent wipe module removed
from the circuit. If the switch is moved to the DE-
LAY position during the next step, the switch will be
damaged.
Test wiper operation in LOW and HIGH speed
modes, and test washer operation. If these modes
were inoperative, but are OK now, replace failed in-
termittent wipe module.
(5) To test the wiper/washer switch, see Windshield
Wiper/Washer Switch Testing. Turn ignition switch to
OFF. Position the wiper switch as indicated, and
back probe wiper switch side of wiring harness con-
nector (black). If switch tests OK, go to step 6. If not
OK, replace switch and go to step 7.
(6) To further test the wiper/washer switch, turn
ignition switch to ACCESSORY or ON. Position thewiper switch as indicated in the tests below, and
back probe wiper switch side of wiring harness con-
nector (black).
(a) Measure voltage at connector terminal E with
wiper switch in LOW, MIST and with washer
switch depressed. Meter should read battery volt-
age. If not OK, replace switch.
(b) Measure voltage at connector terminal C with
wiper switch in HIGH. Meter should read battery
voltage. If not OK, replace switch.
(c) With wiper switch in LOW or HIGH, measure
voltage at connector terminal F, then move wiper
switch to OFF. Meter should read battery voltage
until wipers park and then zero volts. If OK, go to
step 7. If not OK, check wiring to wiper motor, then
go to step 8.
(7) To test the wiper motor, turn the ignition
switch to ACCESSORY or ON. Position the wiper
switch and back probe the motor connector as indi-
cated.
(a) Wiper switch in any position, measure volt-
age at terminal B. Meter should read battery volt-
age. If not OK, repair wiring from circuit breaker.
(b) Wiper switch in LOW, measure voltage at ter-
minal A. Meter should read battery voltage. If OK,
but wipers do not operate, replace failed wiper mo-
tor. If not OK, repair wiring from switch or inter-
mittent wipe module connector.
(c) Wiper switch in HIGH, measure voltage at
terminal H. Meter should read battery voltage. If
OK, but wipers do not operate, replace failed wiper
motor. If not OK, repair wiring from switch or in-
termittent wipe module connector.
(d) Wiper switch in LOW or HIGH, voltmeter
connected to terminal D. Turn wiper switch to OFF
and observe meter. Meter should read battery volt-
age when switch goes to OFF, then zero volts after
wipers park. If battery voltage is present, but wip-
ers fail to park; or, if no battery voltage present, re-
place failed wiper motor.
WINDSHIELD WASHER SYSTEM
WITH NON-INTERMITTENT WIPE
(1) Measure resistance from washer pump connec-
tor terminal B to a clean chassis ground. Meter
should read zero ohms. If not OK, repair open be-
tween terminal B and ground.
(2) Turn ignition switch to ON and press washer
switch.
(a) Measure voltage at switch connector terminal
B. Meter should read battery voltage. If not OK, re-
place wiper/washer switch.
(b) Measure voltage at washer pump connector
terminal A. Meter should read battery voltage. If

MULTI-FUNCTION SWITCH TESTING
PROCEDURESÐXJ
The multi-function switch contains electrical cir-
cuitry for:
²Headlamp Dimmer Switch.
²Passing Lights.
²Turn Signals.
²Hazard Warning.
²Windshield Wiper.
²Pulse Wiper.
²Windshield Washer.
This integrated switch is mounted to the left hand
side of the steering column. Should any function of
the switch fail, the entire switch must be replaced.
The multi-function switch also serves as a fog lamp
lock-out circuit. The circuit to the fog lamp switch is
completed only when the dimmer switch is in the low
beam position.
