INSTALLATION

NOTE: Be certain that the rear wiper motor is in the park position before attempting to install the wiper arm. Turn the ignition switch to the On position and move the rear wiper and washer switch rocker to its Off position. If the wiper motor output shaft moves, wait until it stops moving, then turn the ignition switch back to the Off position. The wiper motor is now in its park position.

Fig. 15 Rear Wiper Arm Installation:

1. The rear wiper arm must be indexed to the rear wiper motor output shaft with the motor in the park position to be properly installed. Position the rear wiper arm pivot end onto the motor output shaft so that the wiper blade is parallel to the lower edge of the upper liftglass blackout area.
2. Once the wiper blade is indexed to the rear wiper motor output shaft, lift the rear wiper arm to its over-center position to hold the wiper blade off of the glass and relieve the spring tension on the wiper arm to rear wiper motor output shaft connection. Using hand pressure, push the tapered hole in the pivot end of the wiper arm down firmly and evenly over the rear wiper motor output shaft.
3. Install and tighten the nut that secures the wiper arm to the rear wiper motor output shaft. Tighten the nut to 12 N.m (9 ft. lbs.). Do not over-tighten.
4. Gently lower the wiper arm until the wiper blade rests on the glass.
5. Wet the liftglass, then operate the rear wiper. Turn the wiper switch to the Off position, then check for the correct wiper arm position and readjust as required
