windshield wipers DODGE RAM 2003 Service User Guide

INSTALLATION
The right and left wiper arms are not interchange-
able. The right wiper arm is slightly longer than the
left. Be certain that each wiper arm is installed on
the proper wiper pivot.
(1) Place the wiper arm hinge in its over-center
position prior to attempting installation.
(2) The wiper arms are indexed to the wiper pivot
shafts with integral keys in the wiper arm pivot ends
and keyways in the wiper pivot shafts. Align the key
of the wiper arm to the keyway on the wiper pivot
shaft.
(3) Once the wiper blade is aligned, push the pivot
of the wiper arm down firmly and evenly over the
wiper pivot shaft until it is fully engaged. When the
wiper arm is fully engaged on the wiper pivot, the
spring-loaded latch (Fig. 19) will snap back into place
against the wiper arm pivot end.
(4) Gently lower the wiper arm until the wiper
blade is in position on the windshield glass.
WIPER BLADE
DESCRIPTION
Each wiper blade is secured by an integral latching
pivot block to the hook formation on the tip of each
wiper arm, and rests on the glass near the base of
the windshield when the wipers are not in operation
(Fig. 20). 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.
All models have two 60.00 centimeter (23.62 inch)
long wiper blades with non-replaceable rubber ele-
ments (squeegees). 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 is
the 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,
yet 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 notched end of the wiper element flexor
should always be oriented towards the end of the
wiper blade that is nearest to the wiper pivot.
(1) 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.
(2) 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
towards the pivot end of the arm far enough to dis-
engage the pivot block from the hook formation on
the end of the arm (Fig. 21).

(3) Extract the hook formation on the tip of the
wiper arm through the opening in the wiper blade
superstructure just 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.
(4) Gently lower the tip of the wiper arm onto the
glass.
INSTALLATION
NOTE: The notched end of the wiper element flexor
should always be oriented towards the end of the
wiper blade that is nearest to the wiper pivot.
(1)
Lift the wiper arm off of the windshield glass,
until the wiper arm hinge is in its over-center position.
(2) Position the wiper blade near the hook forma-
tion on the tip of the arm with the notched end of the
wiper element flexor oriented towards the end of the
wiper arm that is nearest to the wiper pivot.
(3) Insert the hook formation on the tip of the
wiper arm through the opening in the wiper blade
superstructure ahead of the wiper blade pivot block/
latch unit far enough to engage the pivot block into
the hook (Fig. 21).
(4) Slide the wiper blade pivot block/latch up into
the hook formation on the tip of the wiper arm until
the latch release tab snaps into its locked position.
Latch engagement will be accompanied by an audible
click.
(5) Gently lower the wiper blade onto the glass.
WIPER HIGH/LOW RELAY
DESCRIPTION
The wiper high/low relay is located in the Inte-
grated Power Module (IPM) in the engine compart-
ment near the battery. The wiper high/low relay is a
conventional International Standards Organization
(ISO) micro relay (Fig. 22). Relays conforming to the
ISO specifications have common physical dimensions,
current capacities, terminal patterns, and terminal
functions. The relay is contained within a small, rect-
angular, molded plastic housing and is connected to
all of the required inputs and outputs by five integral
male spade-type terminals that extend from the bot-
tom of the relay base.
The wiper high/low relay cannot be adjusted or
repaired and, if faulty or damaged, the unit must be
replaced.
OPERATION
The wiper high/low relay is an electromechanical
switch that uses a low current input from the Front
Control Module (FCM) to control a high current out-
put to the wiper motor. The movable common feed
contact point is held against the fixed normally
closed contact 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 normally closed contact point, and
holds it against the fixed normally open contact
point. When the relay coil is de-energized, spring
pressure returns the movable contact point back
against the fixed normally closed contact point. A
resistor is connected in parallel with the relay coil in
the relay, and helps to dissipate voltage spikes and
electromagnetic interference that can be generated as
the electromagnetic field of the relay coil collapses.
