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.
1. Disengage the rear wiper arm support from the rear wiper arm park ramp on the right side of the liftgate just below the flip-up glass opening.
2. Lift the rear wiper arm (1) to the over-center hinge position,
which will raise the wiper blade and element away from the liftgate and the flip-up glass.
3. To remove the blade (2) from the arm, swing the end of the wiper blade nearest to the wiper motor away from the wiper arm to its travel limit.
4. Now press the end of the wiper blade nearest to the wiper motor away from the wiper arm against its stop far enough to unsnap the wiper blade pivot pin (3) from the latch features on the underside of the wiper arm.
