WIPER ARM
DESCRIPTION
The wiper arms are the rigid members located
between the wiper pivots that protrude from the cowl
plenum cover/grille panel near the base of the wind-
shield and the wiper blades on the windshield glass.
The wiper arm has a die cast metal pivot end. On the
underside of this pivot end is a socket formation with
internal serrations and a small, movable, stamped
steel latch plate that is secured loosely under a small
strap that is staked to the pivot end. 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 hooked through a hole in a small
stamped steel strap on the hinge pin within 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 visible surfaces.
A wiper arm cannot be adjusted or repaired. If
damaged or faulty, the entire wiper arm unit must be
replaced.
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 socket
formation with internal serrations in the wiper arm
pivot end interlocks with the serrations on the outer
circumference of the wiper pivot driver, allowing pos-
itive engagement and finite adjustment of this con-
nection. The latch plate on the underside of the
wiper arm pivot end locks the wiper arm to the wiper
pivot when in its installed position and, when in its
unlocked position, also serves as a blocker to hold the
spring-loaded wiper arm off of the glass to facilitate
removal and installation. 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 cradle for securing and latching the wiper
blade pivot block to the wiper arm.
REMOVAL
(1) Unlatch and open the hood.
(2) Lift the wiper arm far enough to raise the
wiper blade off of the glass and permit the wiper arm
latch plate to be pulled out to its holding position,
then release the arm (Fig. 5). The wiper arm and
blade will remain off the glass with the latch in this
position.
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.
(3) Using a slight rocking motion, remove the
wiper arm pivot end from the wiper pivot.
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 wiper control knob on the end of the
multi-function switch control stalk to its Off posi-
tion. If the wiper pivots move, wait until they stop
moving, then turn the ignition switch back to theOff position. The wiper motor is now in its park
position.
(1) The wiper arms must be indexed to the wiper
pivots with the wiper motor in the park position to
be properly installed (Fig. 6). Position the wiper arm
pivot ends onto the wiper pivots so that the lower
edge of the wiper arm tip is on the upper edge of the
lower windshield blackout area   22 millimeters ( 
0.86 inches).
(2) Once the wiper arm is indexed to the wiper
pivot, lift the wiper arm away from the windshield
slightly to relieve the spring tension on the latch
plate, then push the latch plate into the locked posi-
tion. Gently lower the wiper arm until the wiper
blade rests on the glass.
(3) Wet the windshield glass, then operate the wip-
ers. Turn the wiper control knob on the end of the
multi-function switch control stalk to the Off posi-
tion, then check for the correct wiper arm position
and adjust as required.
WIPER BLADE
DESCRIPTION
Each wiper blade is secured by an integral latching
pivot block to the hook formation on the tip of the
wiper arms, and rests on the glass near the base of
the windshield when the wipers are not in operation.
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 each side of the wiper
element where it is gripped by the claws of the
superstructure.Fig. 5 Wiper Arm Remove/Install - Typical
Fig. 6 Wiper Arm Installation
8R - 12 WIPERS/WASHERSBR/BE
WIPER ARM (Continued)

All Ram truck models have two 50 centimeter
(19.69 inch) wiper blades with non-replaceable rub-
ber elements (squeegees). 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 blade is moved back and forth across the
glass by the wiper arms when the wipers are being
operated. The wiper blade superstructure is the flex-
ible 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 found
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 element 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 clean-
ing edge to the other each time the wiper blade
changes directions.
REMOVAL
NOTE: The driver side and passenger side wiper
blades are not interchangeable. The driver side
wiper blade has an extra bridge and eight pairs of
claws securing the wiper element. The passenger
side wiper blade has six pairs of claws securing the
wiper element. The notched retainer end of both
wiper elements should always be oriented towards
the end of the wiper blade that is nearest to the
wiper pivot.
(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.
(3) To remove the wiper blade from the wiper arm,
push the pivot block latch release tab under the tip
of the arm and slide the blade away from the tip
towards the pivot end of the arm far enough to dis-
engage the pivot block from the hook (Fig. 7).
(4) Extract the hook formation on the tip of the
wiper arm from the opening in the wiper blade
superstructure ahead of the wiper blade pivot block/
latch unit.CAUTION: Do not allow the wiper arm to spring
back against the glass without the wiper blade in
place or the glass may be damaged.
(5) Gently lower the wiper arm tip onto the glass.

WIPER MODULE
DESCRIPTION
The wiper module is secured with screws to the
cowl plenum panel and concealed within the cowl
plenum area beneath the cowl plenum cover/grille
panel. The ends of the wiper pivot shafts that pro-
trude through dedicated openings in the cowl plenum

WIPER BLADE (Continued)

cover/grille panel to drive the wiper arms and blades
are the only visible components of the wiper module.
The wiper module consists of the following major
components:
²Bracket- The wiper module bracket consists of
a long tubular steel main member that has a
stamped pivot bracket formation near each end
where the two wiper pivots are secured. A stamped
steel mounting plate for the wiper motor is secured
with welds near the center of the main member.
²Crank Arm- The wiper motor crank arm is a
stamped steel unit that has a slotted hole on the
driven end that is secured to the wiper motor output
shaft with a nut, and has a ball stud secured to the
drive end.
²Linkage- The two wiper linkage members are
each constructed of stamped steel. A driver side drive
link with a plastic socket-type bushing in the left
end, and a plastic sleeve-type bushing in the right
end. Socket bushing is snap-fit over the pivot ball
stud on the left pivot, while the sleeve bushing is fit
over the longer wiper motor crank arm pivot stud.
The passenger side drive link has a plastic socket-
type bushing on each end. One end of this drive link
is snap-fit over the pivot ball stud on the right pivot,
while the other end is snap-fit over the exposed end
of the longer ball stud on the wiper motor crank arm.
²Motor- The wiper motor is secured with three
screws to the motor mounting plate near the center
of the wiper module bracket. The wiper motor output
shaft passes through a hole in the module bracket,
where a nut secures the wiper motor crank arm to
the motor output shaft. The two-speed permanent
magnet wiper motor features an integral transmis-
sion, an internal park switch, and an internal Posi-
tive Temperature Coefficient (PTC) circuit breaker.
²Pivots- The two wiper pivots are secured to the
ends of the wiper module bracket. 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 has an externally serrated drum secured to it.
The wiper module cannot be adjusted or repaired.
If any component of the module is faulty or damaged,
the entire wiper module unit must be replaced.
OPERATION
The wiper module operation is controlled by the
vehicle operator through battery current inputs
received by the wiper motor from the multi-function
switch on the steering column. The wiper motor
speed is controlled by current flow to either the low
speed or the high speed set of brushes. The park
switch is a single pole, single throw, momentary
switch within the wiper motor that is mechanically
actuated by the wiper motor transmission compo-nents. The park switch alternately closes the wiper
park switch sense circuit to ground or to battery cur-
rent, depending upon the position of the wipers on
the glass. This feature allows the motor to complete
its current wipe cycle after the wiper system has
been turned Off, and to park the wiper blades in the
lowest portion of the wipe pattern. The automatic
resetting circuit breaker protects the motor from
overloads. The wiper motor crank arm, the two wiper
linkage members, 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.

WIPER RELAY
DESCRIPTION
The wiper relay (or intermittent wipe relay) is
located in the Power Distribution Center (PDC) near
the battery in the engine compartment. See the fuse
and relay layout label affixed to the inside surface of
the PDC cover for wiper relay identification and loca-
tion. The wiper relay is a conventional International
Standards Organization (ISO) micro relay. Relays
conforming to the ISO specifications have common
physical dimensions, current capacities, terminal pat-
terns, and terminal functions. The relay is containedwithin a small, rectangular, molded plastic housing.
The relay is connected to all of the required inputs
and outputs through its PDC receptacle by five male
spade-type terminals that extend from the bottom of
the relay base. The ISO designation for each termi-
nal is molded into the base adjacent to the terminal.
The ISO terminal designations are as follows:
²30 (Common Feed)- This terminal is con-
nected to the movable contact point of the relay.
²85 (Coil Ground)- This terminal is connected
to the ground feed side of the relay control coil.
²86 (Coil Battery)- This terminal is connected
to the battery feed side of the relay control coil.
²87 (Normally Open)- This terminal is con-
nected to the normally open fixed contact point of the
relay.
²87A (Normally Closed)- This terminal is con-
nected to the normally closed fixed contact point of
the relay.
The wiper relay cannot be adjusted or repaired. If
the relay is damaged or faulty, it must be replaced.
OPERATION
The wiper relay (or intermittent wipe relay) is an
electromechanical switch that uses a low current
input from the Central Timer Module (CTM) to con-
trol a high current output to the low speed brush of
the wiper motor. The movable common feed contact
point is held against the fixed normally closed con-
tact point by spring pressure. When the relay coil is
energized, an electromagnetic field is produced by the
coil windings. This electromagnetic field draws the
movable relay contact point away from the fixed nor-
mally closed contact point, and holds it against the
fixed normally open contact point. When the relay
coil is de-energized, spring pressure returns the mov-
able contact point back against the fixed normally
closed contact point. A resistor or diode is connected
in parallel with the relay coil in the relay, and helps
to dissipate voltage spikes and electromagnetic inter-
ference that can be generated as the electromagnetic
field of the relay coil collapses.
The wiper relay terminals are connected to the
vehicle electrical system through a connector recepta-
cle in the Power Distribution Center (PDC). The
inputs and outputs of the wiper relay include:
²The common feed terminal (30) is connected to
the wiper motor low speed brush through the wiper
control circuitry of the multi-function switch on the
steering column. When the wiper relay is de-ener-
gized, the common feed terminal is connected to the
wiper park switch output through the wiper park
switch sense circuit. The wiper park switch output
may be battery current (wipers are not parked), or
ground (wipers are parked). When the wiper relay is
energized, the common feed terminal of the wiper is
