For wiper blade element replacement, please refer to Repair Guide .
Removal of the wiper arms requires the use of a special tool, GM J8966 or its 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.
Raising the hood on most later models will facilitate easier wiper arm removal.
- Disconnect the washer hose from the arm (if so equipped). Remove the arm.
- Installation is in the reverse order of removal. The proper park position for the arms is with the blades approximately 2 in. (50mm) above the lower molding of the windshield. Be sure that the motor is in the park position before installing the arms.
