REMOVAL & INSTALLATION
Removal of the wiper arms requires the use of a special tool, G.M. J-8966, or the equivalent. Versions of this tool are generally available in auto parts stores.
- Insert the tool under the wiper arm and lever the arm off the shaft.
- Detach the washer hose from the arm.
- Remove the arm. Installation is the reverse. The proper park position for the arms is with the blades approximately 2 inches (50 mm) above the lower molding of the windshield. Be sure the motor is in the park position before installing the arms.
