2003 DODGE RAM frame

This model is equipped with a Lower Anchors and
Tether for CHildren, or LATCH child restraint
anchorage system (Fig. 10) or (Fig. 11). The LATCH
system provides for the installation of suitable child
restraints in certain seating positions without using
the standard equipment seat belt provided for that
seating position. Standard cab models are equipped
with a fixed-position child restraint upper tether
anchor for the front center and outboard seating posi-
tions, and child restraint lower anchors for the front
outboard seating position. Quad cab models are
equipped with a fixed-position child restraint upper
tether anchor strap for the rear center and both rear
outboard seating positions, and child restraint lower
anchors for both rear outboard seating positions. All
front seat child restraint anchors are deleted on quad
cab models.
The two upper tether anchors for standard cab
models are integral to the upper cab back panel rein-
forcement and are concealed behind individual trim
cover and bezel units that are integral to the cab
back trim panel (Fig. 12). These upper tether anchors
cannot be adjusted or repaired and, if faulty or dam-
aged, they must be replaced as a unit with the upper
cab back panel reinforcement. The upper tether
anchor trim covers and bezels are serviced as a unit
with the cab back trim panel.
The three upper tether anchor straps for quad cab
models are secured to the upper cab back panel rein-
forcement with screws (Fig. 13). These anchor straps
are concealed behind the upright rear seat back. Theupper tether anchor straps are available for individ-
ual service replacement.
The lower anchors for all models are integral to
their respective front or rear seat cushion frame (Fig.
14) or (Fig. 15). Round markers with an imprinted
child seat icon on the standard cab front seat back
trim cover helps identify the anchor locations for that
application because they may be otherwise difficult to
see with the seat back in the upright position. These
lower anchors are each constructed from round steel

bar stock that is formed into a U-shape, then
securely welded at each end to the seat cushion
frame. They are each accessed from the front of their
respective seats, at each side where the seat back
meets the seat cushion. These lower anchors cannot
be adjusted or repaired and, if faulty or damaged,
they must be replaced as a unit with the seat cush-
ion frame. On quad cab models, if the lower anchors
have been bent or broken as a result of a vehicle col-
lision, the latch for the affected rear seat cushion
frame unit must also be replaced.WARNING: DURING AND FOLLOWING ANY SEAT
BELT OR CHILD RESTRAINT ANCHOR SERVICE,
CAREFULLY INSPECT ALL SEAT BELTS, BUCKLES,
MOUNTING HARDWARE, RETRACTORS, TETHER
STRAPS, AND ANCHORS FOR PROPER INSTALLA-
TION, OPERATION, OR DAMAGE. REPLACE ANY
BELT THAT IS CUT, FRAYED, OR TORN.
STRAIGHTEN ANY BELT THAT IS TWISTED.
TIGHTEN ANY LOOSE FASTENERS. REPLACE ANY
BELT THAT HAS A DAMAGED OR INOPERATIVE
BUCKLE OR RETRACTOR. REPLACE ANY BELT
THAT HAS A BENT OR DAMAGED LATCH PLATE
OR ANCHOR PLATE. REPLACE ANY CHILD
RESTRAINT ANCHOR OR THE UNIT TO WHICH THE
ANCHOR IS INTEGRAL THAT HAS BEEN BENT OR
DAMAGED. NEVER ATTEMPT TO REPAIR A SEAT
BELT OR CHILD RESTRAINT COMPONENT.
ALWAYS REPLACE DAMAGED OR FAULTY SEAT
BELT AND CHILD RESTRAINT COMPONENTS WITH
THE CORRECT, NEW AND UNUSED REPLACEMENT
PARTS LISTED IN THE DAIMLERCHRYSLER MOPAR
PARTS CATALOG.
OPERATION
See the owner's manual in the vehicle glove box for
more information on the proper use of all of the fac-
tory-installed child restraint anchors.
REMOVAL
The following procedure applies only to the rear
seat upper child tether straps used on quad cab mod-
els. The child restraint anchors used in other models
and locations are integral to other components and
cannot be serviced separately.

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).
