8R - 10 WIPERS/WASHERS
WASHER NOZZLE (Continued)
windshield glass. The washer plumbing fittings for
the washer nozzles are concealed beneath the cowl
plenum cover/grille panel. These fluidic washer noz-
zles are constructed of molded plastic. The cowl ple-
num cover/grille panel must be removed from the
vehicle to access the nozzles for service. The washer
nozzles cannot be adjusted or repaired and, if faulty
or damaged, they must be replaced.
OPERATION
The two washer nozzles are designed to dispense
washer fluid into the wiper pattern area on the out-
side of the windshield glass. Pressurized washer fluid
is fed to each nozzle from the washer reservoir by the
washer pump/motor through rubber hoses, which are
attached to a barbed nipple on each washer nozzle
below the cowl plenum cover/grille panel. The washer
nozzles incorporate a fluidic design, which causes the
nozzle to emit the pressurized washer fluid as an
oscillating stream to more effectively cover a larger
area of the glass area to be cleaned.
REMOVAL
(1) Remove the wiper arms from the wiper pivots.
(Refer to 8 - ELECTRICAL/WIPERS/WASHERS/
WIPER ARMS - REMOVAL).
(2) Remove the cowl plenum cover/grille panel
from the top of the cowl plenum. (Refer to 23 -
BODY/EXTERIOR/COWL GRILLE - REMOVAL).
(3) From the underside of the cowl plenum cover/
grille panel, disconnect the washer hose from the
nozzle fitting.
(4) From the underside of the cowl plenum cover/
grille panel, compress the snap features of the
washer nozzle and push the nozzle out through the
top of the panel.
INSTALLATION
(1) Align the washer nozzle with the opening on
the top of cowl plenum cover/grille panel.
(2) Using hand pressure, push the washer nozzle
into the opening from the top of the cowl plenum cov-
er/grille panel until the snap features of the nozzle
are fully engaged.
(3) From the underside of the cowl plenum cover/
grille panel, reconnect the washer hose to the nozzle
fitting.
(4) Reinstall the cowl plenum cover/grille panel
onto the top of the cowl plenum. (Refer to 23 - BODY/
EXTERIOR/COWL GRILLE - INSTALLATION).
(5) Reinstall the wiper arms onto the wiper pivots.
(Refer to 8 - ELECTRICAL/WIPERS/WASHERS/
WIPER ARMS - INSTALLATION).
WASHER PUMP/MOTOR
DESCRIPTION
The washer pump/motor unit is located on the out-
board side of the washer reservoir, near the bottom
in the right front corner of the engine compartment.
A small permanently lubricated and sealed electric
motor is coupled to the rotor-type washer pump. A
seal flange with a large barbed inlet nipple on the
pump housing passes through a rubber grommet seal
installed in the dedicated mounting hole near the
bottom of the washer reservoir. A smaller barbed out-
let nipple on the pump housing connects the unit to
the washer hose. The washer pump/motor unit is
retained on the reservoir by the interference fit
between the barbed pump inlet nipple and the grom-
met seal, which is a light press fit. An integral elec-
trical connector receptacle is located on the motor
housing. The washer pump/motor unit cannot be
repaired. If faulty or damaged, the entire washer
pump/motor unit must be replaced.
OPERATION
The washer pump/motor unit is connected to the
vehicle electrical system through a single take out
and two-cavity connector of the headlamp and dash
wire harness. The washer pump/motor is grounded at
all times through a take out of the headlamp and
dash wire harness with a single eyelet terminal con-
nector that is secured by a nut to a ground stud
located on the right front fender inner shield in the
engine compartment.
receives battery current on a front washer pump/mo-
tor control circuit through an output of the Central
Timer Module (CTM) whenever the CTM receives an
input through the closed contacts of the momentary
washer switch within the multi-function switch.
Washer fluid is gravity-fed from the washer reservoir
to the inlet side of the washer pump. When the pump
motor is energized, the rotor-type pump pressurizes
the washer fluid and forces it through the pump out-
let nipple, the washer plumbing, and the washer noz-
zles onto the windshield glass.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Disconnect the headlamp and dash wire har-
ness connector for the washer pump/motor from the
motor connector receptacle (Fig. 3).
(3) Disconnect the washer supply hose from the
barbed outlet nipple of the washer pump/motor and
allow the washer fluid to drain into a clean container
for reuse.
(4) Using a trim stick or another suitable wide
flat-bladed tool, gently pry the barbed inlet nipple of
