Rear blade removal: 1. Disengage the rear wiper arm support from the rubber rear wiper arm park ramp on the right side of the liftgate just below the liftgate flip-up glass. 2. Lift the rear wiper arm to engage the arm hinge in its over-center position with the wiper blade and element off of the liftgate and the glass. 3. 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. 4. 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. 5. 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 liftgate or the glass without the wiper blade in place or they may be damaged. 6. Gently lower the wiper arm and place the arm support in the park ramp.
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 liftgate park ramp. 2. Position the rear wiper blade near the hook formation 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. 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 arm and place the arm support on the park ramp.
2. Using a 13mm socket or wrench, 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. If necessary, use a battery terminal puller to disengage the wiper arm from the rear wiper motor output shaft splines. 5. Remove the rear wiper arm pivot end from the motor output shaft.
1. The rear wiper arm must be indexed to the motor output shaft with the rear wiper motor in the park position to be properly installed. Place the wiper arm onto the liftgate with the wiper arm support positioned on the park ramp and the tapered mounting hole on the pivot end of the arm positioned over the rear wiper motor output shaft. 2. With the wiper arm in the Installation Position, push the tapered mounting hole on the pivot end of the wiper arm down over the rear wiper motor output shaft. 3. Install and tighten the nut that secures the rear wiper arm to the rear wiper motor output shaft. Tighten the nut to 18 N搶 (13 ft. lbs.) 4. Reinstall the plastic nut cap over the nut on the rear wiper motor output shaft end of the rear wiper arm. 5. Lift the rear wiper arm support away from the park ramp, then place the wiper arm support in the park ramp in the Park Position.
