shield. The one way flow check valves are located in
each hood nozzle. The purpose of the check valves is
to improve fluid flow response time and to prevent
excessive washer fluid staining the surface of the
hood. The hood mounted nozzles distribute washer
fluid on the surface of the windshield. The nozzles
are adjustable, refer to the Washer Nozzle Adjusting
Procedures. The pump and reservoir are serviced as
separate assemblies.
WIPER BLADES
When the wiper blade rubber element is exposed to
the weather for a long period of time, it tends to lose
wiping ability. Periodic cleaning of the wiper blade
element is suggested to remove the accumulation of
salt and road film. The wiper blades, arms, and
windshield should be cleaned with a sponge or cloth
and a mild detergent or non abrasive cleaner. If the
blades continue to streak or smear, they should be
replaced. The left wiper blade length is 600 mm. The
right wiper blade length is 550 mm.
DIAGNOSIS AND TESTING
INTERMITTENT WIPER FUNCTION
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS,
SEE GROUP 8M, RESTRAINT SYSTEMS FOR STEER-
ING WHEEL OR COLUMN REMOVAL PROCEDURES.
The intermittent wiper function is controlled by the
Body Control Module (BCM), located in the left side of
the instrument panel, attached to the Junction Block
(Fig. 1). If the Body Control Module is determined to be
the problem, refer to Group 8E, Instrument Panels and
Systems, for replacement procedures.
MULTI-FUNCTION WIPER SWITCH
To test the multi-function switch, first disconnect
the switch wires from the body wiring in the steering
column (Fig. 2). Using an ohmmeter, test for continu-
ity between the terminals of the switch, as indicated
in the following continuity table. The identity of each
terminal is shown in (Fig. 3).
For test purposes, the first position is the OFF
position, the next six positions are for the DELAY
wipe. LOW is the next detent position and HIGH is
the full counterclockwise detent position.
In any wiper switch position, if the Control Stalk end
cap is depressed, the washer circuit will be completed.
