What causes wiper blade to move up while driving?

Wiper blades may move up while driving due to a malfunction in the windshield wiper system, often caused by a faulty wiper motor, a damaged linkage, or an issue with the control switch. Additionally, if the wiper blades are not properly secured to the arm, they can lift away from the windshield at higher speeds. Extreme weather conditions, such as strong winds or heavy rain, can also contribute to this behavior. Regular maintenance and inspection of the wiper system can help prevent such issues.
