How do you change the wiper blades on a 2001 LS 430?

To change the wiper blades on a 2001 Lexus LS 430, first lift the wiper arm away from the windshield. Press the tab on the underside of the wiper blade to release it from the arm, then slide it off. Align the new wiper blade with the arm, slide it into place until you hear a click, and then lower the wiper arm back onto the windshield. Repeat the process for the other blade, if necessary.
