How do you replace windshield wiper on a 2007 Chevy van express?

To replace the windshield wiper on a 2007 Chevy Express van, first lift the wiper arm away from the windshield. Locate the release tab on the wiper blade where it connects to the arm, press it, and slide the old blade off. Align the new wiper blade with the arm’s hook, slide it on until you hear a click, and gently lower the arm back onto the windshield. Repeat the process for the other wiper if necessary.
