GENERAL INFORMATION
INTRODUCTION
Windshield wiper and washer systems are stan-
dard factory-installed equipment on this model. A
rear wiper and washer system is optional factory-in-
stalled equipment. Following is general information
about the available wiper and washer systems for
this vehicle. Refer to 8W-53 - Wipers in Group 8W -
Wiring Diagrams for complete circuit descriptions
and diagrams.
NOTE: This group covers both Left-Hand Drive
(LHD) and Right-Hand Drive (RHD) versions of this
model. Whenever required and feasible, the RHD
versions of affected vehicle components have been
constructed as mirror-image of the LHD versions.
While most of the illustrations used in this group
represent only the LHD version, the diagnostic and
service procedures outlined can generally be
applied to either version. Exceptions to this rule
have been clearly identified as LHD or RHD, if a
special illustration or procedure is required.
WINDSHIELD WIPER SYSTEM
An intermittent windshield wiper system is stan-
dard equipment on this model. The intermittent
wiper system lets the driver select from either of two
wiper speeds, low or high, or the intermittent wipe
delay mode.

The intermittent wipe mode delay times are driver
adjustable from about one second to about fifteen sec-
onds. The intermittent wipe mode is provided by
delay logic and relay control circuitry contained
within the intermittent wiper/washer switch. The
intermittent wipe relay is also contained within the
switch.
The windshield wipers will operate only when the
ignition switch is in the Accessory or On positions. A
circuit breaker located in the junction block protects
the circuitry of the windshield wiper system. Refer to
the owner's manual in the vehicle glove box for more
information on the features, use and operation of the
windshield wiper system.
WINDSHIELD WASHER SYSTEM
An electrically operated windshield washer system
is standard equipment. The washer reservoir is
located between the inner and outer front fenders,
above and forward of the left front wheel housing.
The reservoir filler neck is located in the engine com-
partment on the left inner fender shield.
The washer reservoir holds the washer fluid, which
is pressurized by a pump when the windshield
washer switch lever is actuated. The windshield
washer pump feeds the pressurized washer fluid
through the washer system plumbing to the wind-
shield washer nozzles.
A low washer fluid warning lamp is standard
equipment on all models equipped with the optional
rear wiper and washer system. The low washer fluid
warning lamp in the instrument cluster will warn
