Note. The wiper arms are very tight on their axles and a puller will probably be needed.
Removing
1. Turn on the wiper motor, then turn it off so that the wiper arms return to their original position.
2. Lift the cover, then remove the wiper arm mounting nut (refer to accompanying illustration).
3. Take away a brush from glass and remove the screen wiper lever from an axis. If the lever cannot be removed, use a puller.
Installation
1. Make sure the lever is installed, then securely tighten the mounting nut and lower the cover.
