Wiper ARM

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 pivot shaft, regardless of how carefully it is installed.

FRONT

(1) Lift the wiper arm to permit the latch to be pulled out to its holding position, then release the arm (Fig. 5). The arm will remain off the windshield with the latch in this position.

(2) Remove the arm from the pivot using a rocking motion.

(3) Install the arm and blade with the wiper motor in the Park position. See the Front Wiper Arm Installation illustration (Fig. 6).

(4) Mount the arms on the pivot shafts so that the distance from the lower edge of the wiper arm tip to the upper edge of the lower windshield moulding is:

•  23 to 52 mm (0.90 to 2.04 inch) on the driver side

• 33 to 62 mm (1.29 to 2.44 inch) on the passenger side.

(5) Lift the wiper arm away from the windshield slightly to relieve the spring tension on the latch.

Push the latch into the locked position and slowly release the arm until the wiper blade rests on the windshield.

(6) Operate the wipers with the windshield glass wet, then turn the wiper switch to the Off position.

Check for the correct wiper arm positioning and readjust if required.

REAR

(1) Disconnect the washer nozzle hose and clip from the external nipple of the rear wiper motor output shaft bezel.

(2) Lift the wiper arm pivot cover and remove the retaining nut (Fig. 7).

(3) Remove the wiper arm from the motor output shaft using a rocking motion.

(4) Install the rear wiper arm with the wiper motor in the Park position. Place the rear wiper blade on the glass so that it is parallel to the liftgate glass opening, and install the wiper arm retaining nut.

(5) Operate the rear wiper with the liftgate glass wet, then turn the rear wiper switch to the Off position so that the blade moves to the Park position.

(6) The measurement from the tip of the blade should now be from 27 to 35 mm (1.06 to 1.38 inch) above the upper edge of the lower liftgate glass seal (Fig. 8). Check for the correct wiper arm positioning and readjust if required.
