Be cautious, as the arm is spring loaded and letting it snap back can crack the windshield or damage your wipers.

You can put a towel down against the windshield if damaging it is a concern.

Carefully pull the wiper arm away from the windshield until it locks in an upright position.

To remove the old wiper blade, press the small tab or release clip at the point where the wiper blade connects to the wiper arm and slide it off.
