    REMOVAL & INSTALLATION



    1989-91 Vehicles

    Raise the blade end of the arm off of the windshield and move the slide latch away from the pivot shaft. This will unlock the wiper arm from the pivot shaft and hold the blade end of the arm off of the glass at the same time. The wiper arm can now be pulled off of the pivot shaft without the aid of any tools.

    To prevent glass and/or paint damage, do not pry the arm from the pivot with metal or sharp tools.

    Turn on the wiper switch and allow the motor to move the pivot shafts 3-4 cycles, then turn off the wiper switch. This will place the pivot shafts in the PARK position. Make sure the switch is not rotated into the INTERVAL position, before installing the blade and arm assembly.

    Position the auxiliary arm over the pivot pin, hold it down and push the main arm head over the pivot shaft. Install the blade and arm assemblies to dimension X, as shown in the figure. Dimension X is the distance between the centerline of the blade element and the arm stop. At the lower settings the arm will be beyond the stop. This is normal. In operation, the arms will assume slightly different positions.

    Raise the blade end of the arm off of the windshield and move the slide latch away from the pivot shaft. This will unlock the wiper arm from the pivot shaft and hold the blade end of the arm off of the glass at the same time. The wiper arm can now be pulled off of the pivot shaft without the aid of any tools.

    To prevent glass and/or paint damage, do not pry the arm from the pivot with metal or sharp tools.

    To install the blade and arm assembly, line up the key on the wiper arm with the keyway in the pivot shaft. Push the arm onto the pivot shaft.

    Hold the main arm head onto the pivot shaft while raising the blade end of the wiper arm and push the slide latch into the lock under the pivot shaft. Then lower the blade to the windshield. If the blade does not touch the windshield, the slide latch is not completely in place.

    After blade and arm installation, operate the wiper switch to cycle the linkage and bring the blade and arm back to the parked position. Check dimension X in the figure. Dimension X in Section A should be 0.2-1.3 in. and dimension X in Section B should be 0.08-1.02 in.

    If adjustment is necessary, remove the blade and arm assemblies and use a small prybar to remove the plastic key from the arm. Turn on the wiper switch and allow the motor to move the pivot shafts 3-4 cycles, then turn off the wiper switch. Reinstall the blade and arm assemblies to dimension X. Install the arm on the pivot shaft, then apply downward pressure on the arm head. Allow the latch to slide under the pivot shaft and slide latch using finger pressure only.
