Wiper Arm: Service and Repair

REMOVAL

Fig. 15 Wiper Arm Remove/Install - Typical:

1. Lift the wiper arm far enough to raise the wiper blade off of the glass and permit the wiper arm latch plate to be pulled out to its holding position, then release the arm. The wiper arm and blade will remain off the glass with the latch in this position.

CAUTION :The use of a screwdriver or other prying tool to remove a wiper arm may distort it. This distortion could allow the arm to come off of the wiper pivot during wiper operation, regardless of how carefully it is reinstalled.

2. Using a slight rocking motion, remove the wiper arm pivot end from the wiper pivot.

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 wiper control knob on the end of the multi-function switch control stalk 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.

Fig. 16 Wiper Arm Installation:

1. The wiper arms must be indexed to the wiper pivots with the wiper motor in the park position to be properly installed. Position the wiper arm pivot ends onto the wiper pivots so that the lower edge of the wiper arm tip is on the upper edge of the lower windshield blackout area ±25 millimeters( ± 0.98 inches).
2. Once the wiper arm is indexed to the wiper pivot, lift the wiper arm away from the windshield slightly to relieve the spring tension on the latch plate, then push the latch plate into the locked position. Gently lower the wiper arm until the wiper blade rests on the glass.
3. Wet the windshield glass, then operate the wipers. Turn the wiper control knob on the end of the multi-function switch control stalk to the OFF position, then check for the correct wiper arm position and adjust as required.
