REMOVAL AND INSTALLATION (Continued)
To remove the rear wiper blade and/or element,
proceed as follows:
(1) Lift the rear wiper arm to raise the wiper blade
and element off of the liftgate glass.
(2) Remove the wiper blade from the wiper arm, or
the wiper element from the wiper blade as follows:
(a) To remove the wiper blade from the wiper
arm, push the release tab under the arm tip and
slide the blade away from the tip towards the rear
wiper motor output shaft end of the arm (Fig. 3).
(b) To remove the wiper element from the wiper
blade, pinch the notched (pivot) end release clip of
the wiper element tightly between the thumb and
forefinger. Then, pull the element firmly towards
the rear wiper motor output shaft to release the
wiper element pinch-release clip from the wiper
blade claws. Once the clip is released from the
claws, the element will slide easily out of the
remaining claws.
(3) Install the wiper blade on the wiper arm, or
the wiper element in the wiper blade as follows:
(a) To install the wiper blade on the wiper arm,
slide the blade retainer into the U-shaped forma-
tion on the tip of the wiper arm until the release
tab snaps into its locked position. Be certain that
the pinch-release clip for the wiper element is ori-
ented towards the end of the wiper blade that is
nearest to the rear wiper motor output shaft.
(b) To install the wiper element in the wiper
blade, start at the rear wiper motor output shaft
end of the blade and slide the element through
each pair of wiper blade claws. The element is fully
installed when the claws on the rear wiper motor
output shaft end of the blade are engaged in the
wiper element retaining clip notches.

(2) Lift the wiper arm to permit the latch to be
pulled out to its holding position, then release the
