WASHER RESERVOIR
DESCRIPTION
A single washer fluid reservoir is used for both the
standard front and optional rear washer systems
(Fig. 24). The molded plastic washer fluid reservoir is
secured to the left front fender wheel house in the
engine compartment. A bright yellow plastic filler cap
is labeled with the International Control and Display
Symbol icon for “Windshield Washer” and the text
“Washer Fluid Only” molded into it and highlighted
in black. The cap hinges on a hinge molded into the
cap and is secured to the reservoir by a hook molded
into the top of the reservoir behind the filler neck.
The cap snaps over the open end of the filler neck
and is sealed with a rubber gasket.
There are separate, dedicated holes on the lower
inboard side of the reservoir provided for the mount-
ing of the front and rear washer/pump motor units.
On models not equipped with the optional rear
washer system, the rear washer pump/motor mount-
ing hole in the washer reservoir is sealed with a
plastic plug. The washer pump/motor units are
secured and sealed to the reservoir by the interfer-
ence fit between the barbed inlet nipple of each
pump and a rubber grommet seal installed in each
pump mounting hole. A locating tab on the bottom of
the reservoir fits into a mating slot in the left front
fender wheel house, and the reservoir is secured to
the wheel house by two screws installed through two
mounting tabs that are integral to the reservoir.
The washer reservoir cannot be repaired and, if faulty
or damaged, it must be replaced. The reservoir filler cap
is available for individual service replacement.
OPERATION
The washer fluid reservoir provides a secure,
on-vehicle storage location for a large reserve of
washer fluid for operation of the standard front and
optional rear washer systems. The washer reservoir
filler cap provides a clearly marked and readily
accessible point from which to add washer fluid to
the reservoir. The front and rear washer/pump motor
units are located in a sump area on the inboard side
of the reservoir to be certain that washer fluid will
be available to the pumps as the fluid level in the
reservoir becomes depleted. The front washer pump/
motor unit is mounted in the lowest position in the
sump so that the front washers will operate even
after the rear washer system will no longer operate.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the two screws that secure the washer
reservoir to the left front fender wheel house (Fig. 25).

REAR WIPERS/WASHERS
DESCRIPTION
An electrically operated fixed speed rear wiper and
washer system is optional factory-installed equip-
ment on this model when it is also equipped with the
optional hardtop roof (Fig. 1). The rear wiper and
washer system includes the following major compo-
nents, which are described in further detail else-
where in this service information:
• Rear Check Valve - The rear washer system
check valve is located near the belt line in the left
rear corner of the passenger compartment in the
vehicle. The rear check valve also serves as the in-
line connector between the body wire harness half
and the hardtop wire harness half of the rear washer
hose plumbing.
• Rear Washer Nozzle - The rear washer nozzle
is located in a mounting hole in the rear liftglass just
below and inboard of the rear wiper motor output
shaft. A plastic nut secures the threaded nipple on
the back of the nozzle to the inside of the liftglass.
• Rear Washer Plumbing - The plumbing for
the rear washer system consists of rubber hoses and
molded plastic fittings. The plumbing is routed along
the left side of the vehicle with the body wire har-
ness from the washer reservoir in the engine com-
partment, through the dash into the passenger
compartment, and back to the left rear corner of the
body. The rear check valve splices the body wire har-
ness half of the washer hose to the hardtop wire har-
ness half of the hose at the left rear corner of the
body. The hardtop wire harness and washer hose are
routed up the left rear corner of the hardtop and over
the upper liftglass opening header to the rear washer
nozzle in the upper right corner of the rear liftglass.
A molded plastic washer hose cap is secured by an
integral bail strap to the body wire harness half of
the rear washer hose near the left rear corner of the
body. This cap serves to plug the rear washer hose
when the hardtop is removed from the vehicle.
