The following procedure is easier if you use GM Windshield Wiper Blade/Arm Removal tool No. J8966 or equivalent.

If the wiper assembly has a press type release tab at the center, simply depress the tab and remove the blade. If the blade has no release tab, use a screwdriver to depress the spring at the center; this will release the assembly. To install the assembly, position the blade over the pin (at the tip of the arm) and press until the spring retainer engages the groove in the pin.

To remove the element, either depress the release button or squeeze the spring type retainer clip (at the outer end) together and slide the blade element out. To install, slide the new element in until it latches.

  1. Insert the tool under the wiper arm and lever the arm off the shaft. If you do not have the tool, use a pick to release the latch at the bottom of the arm.
  2.  
  3. Disconnect the washer hose from the arm (if equipped), then remove the arm.
  4.  

To install:
  1. Operate the wiper motor (momentarily) to position the pivot shafts into the park position. The proper park position for the arms is with the blades approximately 50mm on the driver's side, or 70mm on the passenger's side, above the lower windshield molding.
  2.  
  3. Connect the water hose and check operation.
