connection. The mounting nut locks the wiper arm to
the threaded stud on the wiper pivot. 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) Lift the front wiper arm to its over-center posi-
tion to hold the wiper blade off of the glass and
relieve the spring tension on the wiper arm to wiper
pivot connection.
(2) Carefully pry the plastic nut cap off of the
pivot end of the wiper arm (Fig. 7).
(3) Remove the nut that secures the wiper arm to
the wiper pivot shaft.
(4) Use a suitable battery terminal puller to disen-
gage the wiper arm from the wiper pivot shaft
splines (Fig. 8).
(5) Remove the front 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 right multi-function switch control knob to
its Off position. If the wiper pivots move, wait until
they stop moving, then turn the ignition switchback to the Off position. The wiper motor is now in
its park position.
(1) The front wiper arms must be indexed to the
wiper pivots with the wiper motor in the park posi-
tion to be properly installed. Position the front wiper
arm pivot ends onto the wiper pivots so that the
lower edge of the blade is aligned with the wiper
alignment lines located in the lower edge of the
windshield glass (Fig. 7).
(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 on the end of the wiper arm down over the
wiper pivot shaft.
(3) Install and tighten the nut that secures the
wiper arm to the wiper pivot shaft. Tighten the nut
to 23.7 N´m (210 in. lbs.).
(4) Wet the windshield glass, then operate the
front wipers. Turn the wiper switch to the Off posi-
tion, then check for the correct wiper arm position
and readjust as required.
(5) Reinstall the plastic nut cap onto the wiper
arm pivot nut.
FRONT WIPER BLADE
DESCRIPTION
Each front wiper blade is secured by an integral
latching pivot block to the hook formation on the tip
of the front wiper arms, and rests on the glass near
the base of the windshield when the wipers are not
in operation (Fig. 9). The wiper blade consists of the
following components:
²Superstructure- The superstructure includes
several stamped steel bridges and links with claw

secured loosely to and pivots on the wiper arm hinge
pin to conceal the wiper arm retaining nut. The wide
end of a tapered, stamped steel channel 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 a wire 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. A molded plastic wiper arm support is snapped
onto the wiper arm strap where it exits the channel.
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 rear wiper arm is designed to mechanically
transmit the motion from the rear wiper motor out-
put shaft to the rear wiper blade. The wiper arm
must be properly indexed to the motor output shaft
in order to maintain the proper wiper blade travel on
the glass. The wiper arm support is designed to lift
and support the rear wiper arm and blade off of the
glass when the rear wiper blade is parked. This sup-
port and the park ramp on the liftgate outer panel
below the glass also provide an alignment reference
to ensure accurate rear wiper arm and blade instal-
lation. The hole with internal serrations in the wiper
arm pivot end interlocks with the serrations on the
outer circumference of the motor output shaft, allow-
ing positive engagement and finite adjustment of this
connection. A hex nut secures the wiper arm pivot
end to the threads on the motor output shaft and the
pivot cover hinges and snaps over this connection for
a neat appearance. 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) Lift the rear wiper arm pivot cover by lifting it
at the rear wiper motor output shaft end of the arm
(Fig. 8).
(2) Remove the nut that secures the rear wiper
arm to the rear wiper motor output shaft.
(3) Lift the rear wiper arm far enough to engage
the over-center arm hinge in its upright position to
hold the wiper blade off of the liftgate.(4) Use a battery terminal puller to disengage the
wiper arm from the rear wiper motor output shaft
splines (Fig. 9).
(5) Remove the rear wiper arm pivot end from the
motor output shaft.
INSTALLATION
NOTE: Always install the wiper arm and blade with
the wiper motor in the Park position.
