REMOVAL & INSTALLATION
Wiper Blade

The wiper blades should be replaced as necessary. Climatic conditions and use will determine their useful life. For vehicles operated daily in congested urban areas, the wiper blades should be replaced at least once a year, or more often if the clearing ability deteriorates.

  1. Lift the wiper arm up and place a soft towel on the base of the windshield should the arm or blade spring back unexpectedly.
  2.  
  3. Press and hold down the release tab on the wiper blade pivot.
  4.  
  5. While holding the release tab down, press the blade downward toward the arm to release the blade.
  6.  
  7. If replacing the insert, lower the wiper arm downward onto the protective cloth until the wiper blade is ready to install.

To install:

  1. If the wiper arms are being installed for the first time, or the wiper motor, linkage or related components have been replaced;
  2.  
    1. Turn the ignition switch to the ON position.
    2.  
    3. Turn the wiper motor ON and allow the wiper motor to operate BEFORE installing the wiper arm/blades, then turn the wiper motor OFF, making sure the system is in the parked position.
    4.  
    5. Turn the ignition switch OFF.
    6.  

  3. Install the arm on the shaft, aligning the matchmarks made during disassembly and press down on the wiper arm until it is fully seated. Install the mounting nut and cover.
  4.  
  5. Start the engine and allow it to idle with all electrical accessories off.
  6.  
  7. Wet the windshield with water and operate the wipers at full speed. If the wiper blades contact the windshield trim, loosen the mounting nut and reposition as necessary. If small adjustments when attempting to reposition the wiper arm are not possible, loosen the wiper arm fastener 1-1 1 / 2 turns and press down on the wiper arm to loosen the pivot. With the wiper mounting nut loosened, pivot the wiper arm back an forth several times before repositioning, and then tighten the mounting nut.

  9. If the wipers chatter when operated on a dampened windshield, check the wiper blade to windshield alignment. Make sure the wiper blades are in good working order and replace if necessary. To check;
  10.  
    1. The ignition ON but do not start the engine.
    2.  
    3. Operate the wipers a their slowest speed.
    4.  
    5. When the wipers are pointing straight up, turn the ignition switch OFF and remove the ignition key.
    6.  
    7. Move the wiper arm slightly, side-to-side and inspect the angle of the blade's contact with the windshield. At rest the blade should be 90° to the surface of the windshield. When the wiper arm is moved side-to-side slightly, the blade's contact angle should be equal in both directions. If an adjustment is needed, wrap masking or electrical tape around the wiper arm about 4 inches (280mm) from the wiper blade pivot. Then wrap a sturdy rag tightly around the tape. Using a suitable pliers, such as a gooseneck pliers or locking pliers grasp the wiper arm firmly and bend the arm as necessary to achieve the proper angle. Wet the windshield and check the operation. If chatter still exists, bend the wiper arm slightly more in the direction that the chatter occurs and recheck.
