REMOVAL
1. Lift the wiper arm (4) to its over-center position to hold the wiper blade (1) off of the glass and relieve the spring tension on the wiper arm to wiper pivot shaft (6) connection.
2. Carefully pry the plastic nut cap (3) off of the pivot end of the wiper arm.
3. Remove the nut (5) that secures the wiper arm to the pivot shaft.
4. If necessary, use a suitable battery terminal puller (3) to disengage the wiper arm (1) from the pivot shaft (2).
5. Remove the wiper arm pivot end from the pivot shaft.
INSTALLATION
NOTE: Be certain that the wiper motor is in the park position before attempting to install the wiper arms. Turn the ignition switch to the On position and move the multi-function switch control knob to its Off position. If the wiper pivots move, wait until they stop moving, then turn the ignition switch back to the Off position. The wiper motor is now in its park position.

1. The wiper arms (4) must be indexed to the pivot shafts (6) with the wiper motor in the park position to be properly installed. Position the wiper arm pivot end onto the pivot shaft so that the lower edge of the wiper blade (1) is aligned with the wiper alignment lines (2) concealed in the upper margin of the lower windshield blackout area.
2. Once the wiper blade is aligned, lift the wiper arm away from the windshield slightly to relieve the spring tension on the pivot end and push the arm down over the pivot shaft.
3. Install and tighten the nut (5) that secures the wiper arm to the pivot shaft. Tighten the nut to 24 N.m (18 ft.lbs.).
4. Wet the windshield glass, then operate the wipers. Turn the wiper switch to the Off position, then check for the correct wiper arm position and readjust as required.
5. Reinstall the plastic nut cap (3) onto the wiper arm pivot nut.
