Various embodiments of a wiper assembly are disclosed which facilitate the removal by complete release or shattering of a frozen mass of ice or snow which has become merely trapped beneath a wiper blade during its movement. In particular, there is described a method and structures for removing such frozen masses by vibrating a wiper blade at high intensity of vibration. The vibrational intensity is normally measured when no frozen masses are present and causes at least parts of the wiper blade to move out of contact with the windshield.
