FRONT WIPERS/WASHERS (Continued)
• Front Wiper Arm - The two front wiper arms
are secured with integral latches to the serrated ends
of the two wiper pivot shafts, which extend through
the cowl plenum cover/grille panel located near the
base of the windshield.
• Front Wiper Blade - The two front wiper
blades are secured to the two front wiper arms with
integral latches, and are parked on the glass near
the bottom of the windshield when the front wiper
system is not in operation.
• Front Wiper Module - The front wiper pivot
shafts are the only visible components of the front
wiper module. The remainder of the module is con-
cealed within the cowl plenum area beneath the cowl
plenum cover/grille panel. The front wiper module
includes the wiper module bracket, three rubber-iso-
lated wiper module mounts, the front wiper motor,
the front wiper motor crank arm, the front wiper
drive link, the front wiper connector link, and the
two front wiper pivots.
• Right Multi-Function Switch - The right
multi-function switch is located near the top of the
steering column, just below the steering wheel. The
right multi-function switch includes a control stalk
with a control knob on the end that extends through
a dedicated opening on the right side of the steering
column shrouds. The right multi-function switch is
dedicated to providing all of the driver controls for
the front wiper and washer systems.
• Washer Reservoir - The molded plastic washer
reservoir is secured by two screws through integral
mounting tabs to the top of the left front fender
wheel house, in the left front corner of the engine
compartment. The washer reservoir filler neck is
accessed from the left front corner of the engine com-
partment.
Hard wired circuitry connects the front wiper and
washer system components to the electrical system of
the vehicle. These hard wired circuits are integral to
several wire harnesses, which are routed throughout
the vehicle and retained by many different methods.
These circuits may be connected to each other, to the
vehicle electrical system and to the front wiper and
washer system components through the use of a com-
bination of soldered splices, splice block connectors,
and many different types of wire harness terminal
connectors and insulators. Refer to the appropriate
wiring information. The wiring information includes
wiring diagrams, proper wire and connector repair
procedures, further details on wire harness routing
and retention, as well as pin-out and location views
for the various wire harness connectors, splices and
grounds.

OPERATING MODES
The components of the wiper and washer system
are designed to work in concert to provide the follow-
ing operating modes:
• Continuous Wipe Modes - The control stalk of
the right multi-function switch has two continuous
wipe positions, Low and High. When selected, these
switch positions will cause the two-speed wiper motor
to operate in a continuous low or high speed cycle.
• Intermittent Wipe Mode - The control stalk of
the right multi-function switch has an intermittent
wipe position, and the control knob has several minor
detent positions which will each cause the wiper sys-
tem to operate at different delay intervals between
complete wipe cycles. The internal circuitry of the
right multi-function switch provides the intermittent
wipe mode and adjustable delay intervals between
wipe cycles of about one second to about fifteen sec-
onds.
• Mist Wipe Mode - The control stalk of the right
multi-function switch has a momentary mist wipe
position that will operate the front wipers for a sin-
gle complete cycle, then park the wiper blades near
the base of the windshield.
• Washer Mode - When the control stalk of right
multi-function switch is pulled toward the steering
wheel to the momentary Wash position while the
front wiper system is operating, washer fluid will be
dispensed onto the windshield glass through the
washer nozzles for as long as the front washer pump
is energized.
• Wipe-After-Wash Mode - When the control
stalk of right multi-function switch is pulled toward
the steering wheel to the momentary Wash position
while the front wiper system is not operating, the
internal circuitry of the right multi-function switch
provides a wipe-after-wash feature which will operate
the front washer pump/motor and the front wipers
for as long as the washer system is activated, then
provide one or two additional wipe cycles after the
washer system is deactivated before parking the
front wiper blades near the base of the windshield.

OPERATION

The front wiper and washer system is designed to
provide the vehicle operator with a convenient, safe,
and reliable means of maintaining visibility through
the windshield glass. The various components of this
system are designed to convert electrical energy pro-
duced by the vehicle electrical system into the
mechanical action of the wiper blades to wipe the
outside surface of the glass, as well as into the
hydraulic action of the washer system to apply
washer fluid stored in an on-board reservoir to the
area of the glass to be wiped. When combined, these
components provide the means to effectively main-
