ing column, behind the steering wheel. The wiper
switch is a resistive multiplexed network that pro-
vides an input to the Body Control Module (BCM)
which then opens/closes the wiper relay.

The wiper system has LOW, HIGH, and INTER-

MITTENT switch positions. The intermittent wiper

system, in addition to low and high speeds, has a
delay mode and a pulse wipe mode.

The intermittent wiper function is integral to the

wiper switch. The wiper switch also includes the
MIST feature which provides a single wipe when
actuated.

The wiper motor is serviced separately from the

wiper assembly. The wiper linkage is crimped onto
the assembly and cannot be detached.

The wiper function can be checked using the DRB

III

t scan tool.

WASHER SYSTEM

This vehicle is equipped with an electrically oper-

ated windshield washer pump. The washers are oper-
ated by a switch in the multi-function switch control
lever (Fig. 1). The lever is located on the right side of
the steering column.

The electric pump assembly is mounted directly to

the reservoir. A permanently lubricated motor is cou-
pled to an impeller type pump. The pump and reser-
voir are serviced as separate assemblies.

OPERATION

WIPER SYSTEM

Move the control lever up to select the desired

wiper speed. Move the lever upward to the second
detent for Low speed wiper operation, or to the third
detent for High speed operation.

Use the intermittent wiper when weather condi-

tions make a single wiping cycle, with a variable
pause between cycles, desirable. Move the lever to
the DEL position, then select the delay interval by
turning the end of the lever. The delay can be regu-
lated from a maximum of approximately 18 ± 0.5 sec-
onds between cycles, to a cycle every second ± 0.5
second.

The windshield wipers will only operate with the

ignition switch in the ACCESSORY or IGNITION
RUN position. The wiper circuit is protected against

over loads by a fuse in the junction block. This pro-
tects the circuitry of the wiper system and the vehi-
cle. The wiper motor has permanent magnet fields.

The intermittent wiper delay mode has a range of

1 ± 0.5 to 18 ± 0.5 seconds. Pulse wipe is accom-
plished by holding stalk lever in the WASH position
momentarily. The wiper blades then sweep once or
twice after the WASH at low speed and then return
to the previous wiper switch mode.

The wiper system completes the wipe cycle when

the switch is turned OFF. The blades park in the
lowest portion of the wipe pattern.

Push down on the wiper lever to activate a single

wipe to clear off road mist or spray from a passing
vehicle. As long as the lever is held down, the wipers
will continue to operate.

WASHER SYSTEM

To use the washer, pull the stalk lever toward you

and hold while spray is desired. If the stalk lever is
pulled while in the delay range, the wiper will oper-
ate for two wipe cycles (± 1) after the stalk lever is
released, and then resume the intermittent interval
previously selected.

The wash function can be accessed in the OFF

position of the wiper control switch. Pulling the
washer stalk lever rearward when the switch is in
the OFF position will operate the wipers and washer
motor pump continuously until the stalk lever is
released. Releasing the stalk lever will stop the
washer pump but the wipers will complete the cur-
rent wipe cycle followed by an average of two more
wipe cycles (± 1) before the wipers park and the mod-
ule turns off.

If the stalk lever is pulled while in the OFF posi-

tion, the wipers will operate for two wipe cycles, then
turn OFF.

Fluid, gravity fed from the reservoir, is forced by

the pump through rubber hoses to the hood mounted
nozzles which direct the fluid streams to the wind-
shield.

DIAGNOSIS AND TESTING - WINDSHIELD
WASHERS

Whenever a windshield washer malfunction occurs,

first verify that the windshield washer wire harness

is properly connected to all connectors before starting
normal diagnosis and repair procedures. Refer to the

WASHER NOZZLE

REMOVAL

To replace nozzle, disconnect washer fluid hose.

Using needle nose pliers, squeeze together the lock-
ing tabs on the nozzle and remove.

INSTALLATION

For installing make sure that both locking tabs are

securely snapped into position. Connect washer fluid
hose. If no washer spray, check fluid hoses for kinks
or leaks.

WASHER RESERVOIR

REMOVAL

(1) Disconnect and isolate the battery negative

remote cable.

(2) Disconnect washer fluid hose at in-line connec-

tor on top of the right shock tower.

(3) Partially remove bumper fascia as needed to

gain access to the reservoir. Refer to Frame &
Bumpers, Bumpers, Front Fascia, Removal.

(4) Disconnect wire connector from washer pump

and harness mounting tab (Fig. 2).

(5) Remove washer reservoir mounting bolts.
(6) Slide rearward and drop down and away from

vehicle.

ADJUSTMENTS - WIPER ARMS

High speed, wet windshield operation, the right

blade tip may override the cowl screen slightly. This
is normal and should not affect wiper system perfor-
mance.

cowl screen edge. The blade should be 18 to 42 mm
(.75 to 1.60 inches.).

(7) If not OK, check for worn parts.
(8) In the event the blade tip strikes the cowl

screen or molding remove arm. Position arm on
windshield and torque nut to 30 ± 3 N·m (22 ± 2 ft.
lbs.) (Fig. 3).
