AMPLIFIER
DESCRIPTION
Models equipped with the Infinity premium
speaker package have a separate power amplifier
unit. This power amplifier is rated at 180 watts out-
put. The power amplifier unit is mounted to the rear
floor panel under the passenger side rear seat cush-
ion. The power amplifier unit can be accessed for ser-
vice by unlatching and tilting the passenger side rear
seat cushion forward.
The power amplifier unit should be checked if
there is no sound output noted from the speakers.
For diagnosis of the power amplifier, (Refer to 8 -
ELECTRICAL/AUDIO/SPEAKER - DIAGNOSIS
AND TESTING). The power amplifier cannot be
repaired or adjusted and, if faulty or damaged, the
unit must be replaced.
OPERATION
The power amplifier is energized by a fused 12 volt
output from the radio receiver whenever the radio is
turned on. The power amplifier receives the sound
signal inputs for four speaker channels from the
radio receiver, then sends the amplified speaker out-
puts for each of those channels to the six Infinity
speakers. For complete circuit diagrams, refer to the
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds.

FRONT WASHER HOSES/
TUBES
DESCRIPTION
The front washer plumbing consists of a small
diameter rubber hose that is routed from the barbed
outlet nipple of the front washer pump/motor on the
washer reservoir along the filler neck into the engine
compartment. In the engine compartment, a molded
plastic in-line fitting with barbed nipples joins the
washer hose to another section of hose that is routed
near the left headlamp and dash wire harness to the
cowl plenum area. The engine compartment washer
hose passes from the engine compartment into the
cowl plenum area through a dedicated hole with a
rubber grommet near the left end of the cowl plenum
panel. A molded plastic elbow fitting with barbed nip-
ples joins the engine compartment hose to the cowl
grille cover hose. The cowl grille cover washer hose is
routed through routing clips on the underside of the
cowl grille cover to a molded plastic wye fitting with
barbed nipples and an integral check valve. The cowl
grille cover hose is connected to one nipple on the
wye fitting and the two washer nozzle hoses are con-
nected to the other two wye fitting nipples. The
washer nozzle hoses are routed along the underside
of the cowl grille cover to the two washer nozzles.

FRONT CHECK VALVE (Continued)

Washer hose is available for service only as roll
stock, which must then be cut to length. The molded
plastic washer hose fittings cannot be repaired. If
these fittings are faulty or damaged, they must be
replaced.
OPERATION
Washer fluid in the washer reservoir is pressurized
and fed by the front washer pump/motor through the
front washer system plumbing and fittings to the two
front washer nozzles. Whenever routing the washer
hose or a wire harness containing a washer hose, it
must be routed away from hot, sharp, or moving
parts; and, sharp bends that might pinch the hose
must be avoided.
FRONT WASHER NOZZLE
DESCRIPTION
The two front washer nozzles have integral snap
features that secure them in dedicated holes in the
cowl plenum cover/grille panel located near the base
of the windshield. The domed upper surface of the
washer nozzle is visible on the top of the plenum cov-
er/grille panel, and the nozzle orifice is oriented
towards the windshield glass. The washer plumbing
fittings for the washer nozzles are concealed beneath
the cowl plenum cover/grille panel. These fluidic
washer nozzles are constructed of molded plastic. The
cowl plenum cover/grille panel must be removed from
the vehicle to access the nozzles for service. The
washer nozzles cannot be adjusted or repaired. If
faulty or damaged, they must be replaced.
OPERATION
The two front washer nozzles are designed to dis-
pense washer fluid into the wiper pattern area on the
outside of the windshield glass. Pressurized washer
fluid is fed to each nozzle from the washer reservoir
by the front washer pump/motor through a single
hose, which is attached to a barbed nipple on each
front washer nozzle below the cowl plenum cover/
grille panel. The washer nozzles incorporate a fluidic
design, which causes the nozzle to emit the pressur-
ized washer fluid as an oscillating stream to more
effectively cover a larger area of the glass area to be
cleaned.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the wiper arms from the wiper pivots.
(Refer to 8 - ELECTRICAL/FRONT WIPERS/WASH-
ERS/FRONT WIPER ARMS - REMOVAL).

hose from the cowl grille cover washer hose at the
plastic elbow connector.
(8) Remove the cowl grille cover from the cowl ple-
num and cowl top panels through the opening
between the hood and the base of the windshield.

connect the washer hose(s) from the barbed nipple(s)
of the front washer nozzle(s).
(10) From the underside of the cowl grille cover,
release the integral snap features of the front washer
nozzle(s) and push the nozzle(s) out through the
mounting hole toward the top side of the cowl grille
cover.

insert the nipple end of the front washer nozzle(s)
through the mounting hole in the cowl grille cover.

washer nozzle until the integral snap features lock
into place on the underside of the cowl grille cover.
(3) From the underside of the cowl grille cover,
reconnect the washer hose(s) to the barbed nipple(s)
of the front washer nozzle(s).

FRONT WASHER PUMP/
MOTOR
DESCRIPTION
The front washer pump/motor unit is located on
the outboard side and near the front of the washer
reservoir, between the left front inner and outer
fender panels (Fig. 5). A small permanently lubri-
cated 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 one of
two dedicated mounting holes near the bottom of the
washer reservoir. The front washer pump/motor unit
is always mounted in the lower pump mounting hole
of the reservoir. A smaller barbed outlet nipple on the
pump housing connects the unit to the front washer
hose. The washer pump/motor unit is retained on the
reservoir by the interference fit between the barbedpump inlet nipple and the grommet seal, which is a
light press fit. An integral electrical connector recep-
tacle is located on the top of the motor housing. The
front washer pump/motor unit cannot be repaired. If
faulty or damaged, the entire washer pump/motor
unit must be replaced.
OPERATION
The front washer pump/motor unit is connected to
the vehicle electrical system through a single take
out and two-cavity connector of the left headlamp
and dash wire harness. The washer pump/motor is
grounded at all times through a take out of the left
headlamp and dash wire harness with a single eyelet
terminal connector that is secured under a ground
screw to the top of the left inner fender shield in the
engine compartment. The front washer pump/motor
receives battery current on a fused ignition switch
output (run-acc) circuit through the closed contacts of
the momentary front washer switch within the right
multi-function switch only when the switch control
stalk is pulled towards the steering wheel. 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 outlet
nipple, the front washer plumbing, and the front
washer nozzles onto the windshield glass.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
