WIPER ARM
DESCRIPTION
The wiper arms are the rigid members located
between the wiper pivots that protrude from the cowl
top panel near the base of the windshield and the
wiper blades on the windshield glass (Fig. 23). These
wiper arms feature an over-center hinge that allows
easy access to the windshield glass for cleaning. The
wiper arm has a die cast metal pivot end with a
large tapered mounting hole at one end. A removable
molded black plastic pivot cover fits loosely over and
pivots on the wiper arm hinge pin, then snaps over
the pivot end to conceal the wiper arm retaining nut.
The wide end of a tapered, stamped steel channel
hinges on and is secured with a hinge pin to the
pivot end of the wiper arm. One end of a long, rigid,
stamped steel strap, with a small hole near its pivot
end, is riveted and crimped within the narrow end of
the stamped steel channel. The tip of the wiper blade
end of this strap is bent back under itself to form a
small hook. Concealed within the stamped steel
channel, one end of a long spring is engaged with awire hook on the underside of the die cast pivot end,
while the other end of the spring is hooked through
the small hole in the steel strap. The entire wiper
arm has a satin black finish applied to all of its vis-
ible surfaces.
Near the hook of the wiper arm steel strap is a
locating hole for the washer nozzle that is mounted
on the wiper arm. A U-shaped molded plastic guard
snaps onto the underside of the strap to conceal and
protect the washer nozzle hose. There are also two
small molded plastic washer nozzle hose routing
brackets clipped onto the underside of the wiper arm
pivot end.
The wiper arms for this model are unequal in
length, with the longer arm being installed on the
left (driver) side of the windshield. A wiper arm can-
not be adjusted or repaired. If damaged or faulty, the
entire wiper arm unit must be replaced. The washer
nozzle, nozzle hose, routing brackets, and pivot end

cover are available for individual service replace-
ment.
OPERATION
The wiper arms are designed to mechanically
transmit the motion from the wiper pivots to the
wiper blades. The wiper arm must be properly
indexed to the wiper pivot in order to maintain the
proper wiper blade travel on the glass. The tapered
mounting hole in the wiper arm pivot end interlocks
with the serrations on the outer circumference of the
wiper pivot shaft, allowing positive engagement and
finite adjustment of this connection. The mounting
nut locks the wiper arm to the threaded end of the
wiper pivot shaft. The spring-loaded wiper arm hinge
controls the down-force applied through the tip of the
wiper arm to the wiper blade on the glass. The hook
formation on the tip of the wiper arm provides a cra-
dle for securing and latching the wiper blade pivot
block to the wiper arm.
REMOVAL
(1) Disconnect the washer nozzle hose from the
elbow fitting on the cowl top panel near the pivot end
of the wiper arm (Fig. 24).
CAUTION: The use of a screwdriver or other prying
tool to remove a wiper arm may distort it. This dis-
tortion could allow the arm to come off of the wiper
pivot during wiper operation, regardless of how
carefully it is reinstalled.
(2) Unsnap the end of the pivot cover from the
wiper blade pivot end, then pull the cover away from
the wiper arm hinge pin to remove the cover from
the wiper blade.(3) Remove the nut that secures the wiper arm to
the wiper pivot shaft.
(4) If necessary, use a suitable battery terminal
puller to disengage the wiper arm from the wiper
pivot shaft (Fig. 25).
(5) Remove the wiper arm pivot end from the
wiper pivot shaft.
INSTALLATION
NOTE: Be certain that the wiper motor is in the park
position before attempting to install the wiper arms.
Turn the ignition switch to the On position and
move the right (wiper) control stalk of the multi-
function switch to its Off position. If the wiper piv-
ots move, wait until they stop moving, then turn the
ignition switch back to the Off position. The wiper
motor is now in its park position.
NOTE: The wiper arms and wiper blades for this
model are both unequal in length, with the longer
arm and blade being installed on the left (driver)
side of the windshield.
(1) The wiper arms must be indexed to the wiper
pivot shafts with the wiper motor in the park posi-
tion to be properly installed. Position the wiper arm
pivot ends onto the wiper pivots so that the lower
edge of the wiper arm tip is aligned with the black
wiper alignment line located near the lower edge of
the windshield glass (Fig. 24).
(2) Once the wiper blade is aligned, lift the wiper
arm away from the windshield slightly to relieve the
spring tension on the pivot end and push the pivot
hole in the pivot end of the arm down firmly and
evenly over the wiper pivot shaft. Gently lower the
wiper arm until the wiper blade rests on the glass.

WIPER BLADE
DESCRIPTION
Each wiper blade is secured by an integral latching
pivot block to the hook formation on the tip of the
wiper arm, and rests on the glass near the base of
the windshield when the wipers are not in operation
(Fig. 26). The wiper blade consists of the following
components:
²Superstructure- The superstructure includes
several stamped steel bridges and links with claw
formations that grip the wiper blade element. Also
included in this unit is the latching, molded plastic
pivot block that secures the superstructure to the
wiper arm. All of the metal components of the wiper
blade have a satin black finish applied.
²Element- The wiper element or squeegee is the
resilient rubber member of the wiper blade that con-
tacts the glass.
²Flexor- The flexor is a rigid metal component
running along the length of the wiper element on
each side, where it is gripped by the claws of the
superstructure.
All Sprinter models have unequal length wiper
blades with non-replaceable rubber elements (squee-
gees). The left (driver) side wiper blade is 60.0 centi-
meters (23.5 inches), and the right (passenger) side
wiper blade is 55.0 centimeter (21.5 inches). These
wiper blades also include an anti-lift feature. The
wiper blades cannot be adjusted or repaired. If faulty,
worn, or damaged the entire wiper blade unit must
be replaced.
OPERATION
The wiper blades are moved back and forth across
the glass by the wiper arms when the wipers are
being operated. The wiper blade superstructure isthe flexible frame that grips the wiper blade element
and evenly distributes the force of the spring-loaded
wiper arm along the length of the element. The com-
bination of the wiper arm force and the flexibility of
the superstructure makes the element conform to
and maintain proper contact with the glass, even as
the blade is moved over the varied curvature that
may be encountered across the glass surface. The
wiper element flexor provides the claws of the blade
superstructure with a rigid, yet flexible component
on the element which can be gripped. The rubber ele-
ment is designed to be stiff enough to maintain an
even cleaning edge as it is drawn across the glass,
but resilient enough to conform to the glass surface
and flip from one cleaning edge to the other each
time the wiper blade changes directions.
REMOVAL
NOTE: The wiper arms and wiper blades for this
model are both unequal in length, with the longer
arm and blade being installed on the left (driver)
side of the windshield.
(1) Turn the wiper control knob on the end of the
multi-function switch control stalk to the On posi-
tion. Cycle the wiper blades to a convenient working
location on the windshield by turning the ignition
switch to the On and Off positions.
(2) Lift the wiper arm to raise the wiper blade and
element off of the glass, until the wiper arm hinge is
in its over-center position.
(3) To remove the wiper blade from the wiper arm,
depress the pivot block latch release tab under the
tip of the arm and slide the blade away from the tip

WIPER LINKAGE
DESCRIPTION
The wiper linkage and pivots are concealed within
the engine compartment below the cowl top panel
(Fig. 28). The ends of the wiper pivot shafts that pro-
trude through dedicated openings in the cowl top
panel to drive the wiper arms and blades are the
only visible components of the wiper linkage module.
The wiper linkage module consists of the following
major components:
²Linkage- The two wiper drive links are each
constructed of stamped steel. The left (driver) side
drive link has a plastic socket-type bushing in one
end, and a plastic sleeve-type bushing in the other
end. The socket bushing is snap-fit over the ball stud
on the left pivot crank arm, while the sleeve bushing
is fit over the longer ball stud on the wiper motor
crank arm. The right (passenger) side drive link has
a plastic socket-type bushing on each end. One end of
this drive link is snap-fit over the exposed end of the
longer ball stud on the wiper motor crank arm and
captures the sleeve bushing end of the left drive link
beneath it, while the other end is snap-fit over the
ball stud on the right pivot crank arm.
²Module Bracket- The linkage module bracket
consists of a long tubular steel main member that is
crimped to a molded plastic pivot bracket at each end
where the wiper pivots are secured. A stamped steel
mounting plate for the wiper motor is secured with
welds near the center of the main member and is
then secured with screws to the underside of the cowl
top panel.
²Motor Crank Arm- The wiper motor crank
arm is a stamped steel unit with a round hole on the
driven end that is secured to the wiper motor outputshaft with a nut, and a long ball stud secured to the
drive end.
²Pivot- The two molded plastic wiper pivot
brackets are secured to the ends of the linkage mod-
ule bracket tubular member. The crank arms that
extend from the bottom of the pivot shafts each have
a ball stud on their end. The upper end of each pivot
shaft where the wiper arms will be fastened each is
tapered and externally serrated with a threaded stud
at the top where the wiper arms are secured by a
nut. Each pivot shaft operates within a housing
formed in the pivot bracket featuring a large external
flange near its center and external threads near the
top. The pivot housings are secured to the outer sur-
face of the cowl top panel by a large washer and a
nut threaded onto the outside of the housing where it
protrudes through the cowl top.
The wiper linkage module cannot be adjusted or
repaired. If any component of the linkage module is
faulty or damaged, the entire wiper linkage module
unit must be replaced.
OPERATION
The wiper linkage operation is controlled by the
output of the wiper motor through the wiper motor
crank arm. The wiper motor crank arm, the two
wiper drive links, and the two wiper pivots mechan-
ically convert the rotary output of the wiper motor to
the back and forth wiping motion of the wiper arms
and blades on the glass.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
