INSTALLATION
FRONT
NOTE: Be certain that the wiper motor is in the park position before attempting to install the front wiper arms. Turn the ignition switch to the On position and move the control knob on the right (wiper) control stalk of the multi-function switch 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 front wiper arms must be indexed to the wiper pivot shafts with the wiper motor in the park position to be properly installed. Position the front wiper arm pivot ends onto the wiper pivot shafts (4) so that the tip of the wiper blade (1) is aligned with the T-shaped wiper alignment lines (5) located in the lower edge of the windshield glass.
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 pivot hole on the end of the wiper arm down firmly and evenly over the wiper pivot shaft.
3. Install and tighten the nut (3) that secures the wiper arm to the wiper pivot shaft. Tighten the nut to 24 N·m (18 ft. lbs.).
4. Wet the windshield glass, then operate the front wipers. Turn the front wipers Off, then check for the correct wiper arm position and readjust as required.
5. Reinstall the plastic nut cap (2) onto the wiper arm pivot nut.
REAR
NOTE: Always install the wiper arm and blade with the wiper motor in the Park position.
1. The rear wiper arm (3) 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 tailgate (1) with the wiper arm support positioned on the park ramp (2) and the tapered mounting hole on the pivot end of the arm positioned over the rear wiper motor output shaft.
2. Position the tab on the back of the rear wiper arm support on the tailgate park ramp in the Installation Position (4).
3. 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.
4. Install and tighten the nut that secures the rear wiper arm to the rear wiper motor output shaft. Tighten the nut to 18 N·m (13 ft. lbs.).
5. Close the rear wiper arm pivot cover.
6. Lift the rear wiper arm (5) support away from the park ramp (7), then place the wiper arm support in the park ramp on the tailgate (8) in the Park Position (6).
