Jeep Grand Cherokee WK. Manual - part 705
OPERATION
The front wiper blades are moved back and forth across the glass by the front 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 combination 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 element 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 front wiper arm (2) to raise the superstruc-
ture (1) and element (6) off of the glass, until the
wiper arm hinge is in its over-center position.
2. Depress the release tab (4) and slide the super-
structure away from the tip of the wiper arm until
the pivot block (3) is disengaged from the hook (5)
on the end of the wiper arm.
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.
3. Extract the hook of the wiper arm from the opening in the wiper blade superstructure and remove the wiper blade
and.
4. Gently lower the tip of the wiper arm back onto the windshield 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 front wiper arm (2) off of the windshield
glass, until the wiper arm hinge is in its over-center
position.
2. Position the front wiper blade near the hook (5)
located on the tip of the wiper arm with the notched
end of the wiper element (6) oriented towards the
end of the arm that is nearest to the wiper pivot.
3. Insert the wiper arm hook through the opening in
the wiper blade superstructure (1) ahead of the
pivot block (3) far enough to engage the pivot block
with the hook.
4. Slide the pivot block up into the hook until the latch release tab (4) snaps into the locked position. Latch engage-
ment will be accompanied by an audible click.
