How to install a wiper blade?
Here’s how to install a wiper blade: If you see a folding cover on the blade, unclip it. If you see a small tab sticking out of the blade frame next to the end of the wiper arm, hold it down. Pull the wiper back toward the bottom of the wiper arm to remove it. Antique vehicles use wipers held onto a pin that sticks out of the wiper arm. Pull the wiper away from the pin, and it should pop off. To remove Rock Lock wiper blades, commonly used on rear window wipers, turn the blade until it’s at a 90 degree angle from the wiper blade, then pull the wiper away from the arm. Install new blades by doing the opposite of what you did for removal.
