adjusted or repaired. If faulty, worn, or damaged the
entire wiper blade unit must be replaced.
OPERATION
The rear wiper blade is moved back and forth
across the glass by the wiper arm when the rear
wiper system is in operation. The wiper blade super-
structure 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 ele-
ment. The combination of the wiper arm force and
the flexibility of the superstructure makes the ele-
ment conform to and maintain proper contact with
the liftglass, even as the blade is moved over the var-
ied curvature found across the glass surface.
The wiper element flexor provides the claws of the
blade superstructure with a rigid, yet flexible compo-
nent on the element which can be gripped. The rub-
ber 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 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 rear wiper motor
output shaft.
(1) Lift the rear wiper arm to raise the wiper blade
and element off of the liftglass.
(2) 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 rear wiper motor output shaft end of the
arm (Fig. 17).
(3) Slide the rear wiper blade away from the tip of
the arm towards the pivot end of the arm far enough
to disengage the pivot block from the hook formation
on the end of the arm.
(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 liftglass without the wiper blade in
place or the glass may be damaged.
(5) Gently lower the wiper arm tip 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 rear wiper motor
output shaft.
(1) Lift the rear wiper arm off of the liftglass.
(2) Position the rear wiper blade near the hook for-
mation 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 rear wiper motor
output shaft.
(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 with
the hook (Fig. 17).
(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.
(5) Gently lower the wiper blade onto the liftglass.
REAR WIPER MOTOR
DESCRIPTION
The rear wiper motor is concealed behind a molded
plastic trim cover on the inside of the liftglass near
the right liftglass hinge at the top of the glass. A
large blackout area of the liftglass conceals the unit
from the exterior of the vehicle. The end of the motor
output shaft that protrudes through a large rubber
grommet in the liftglass to drive the rear wiper arm
and blade is the only visible component of the rear
wiper motor (Fig. 18). A large flat washer and a nut
secure and seal the motor output shaft to the outside
of the liftglass, while a rubber insulator in a slot on
the outboard upper corner of the motor bracket is
secured by a stud and nut to the inside of the lift-
glass near the right liftglass hinge. The connector of
a short pigtail harness is secured to a tab on the
back of the motor bracket, and connects the rear
wiper motor to the vehicle electrical system through
a dedicated take out and connector of the hardtop
