The video above shows how to remove and replace windshield wiper blades that have a flip up type connection. The steps are fairly easy - flip up the top plastic piece and slide the wiper blade down the arm. To replace the windshield wiper blade, flip up the top plastic part of the new blade and slide the new windshield wiper blade up the arm, then swing the top down to secure the wiper blade to the windshield wiper arm.
Even if only one wiper is streaking, we recommend that you replace both wiper blades in pairs because the rubber on both blades wears out equally. It is best to replace your wipers once a year, even if you live in an area that doesn't rain often - the sun wears out your wiper blades more than using them to wipe water. Another tip is to scrape off ice and snow from your windshield before using your wipers - the ice has small crystals that cause microscopic slices in the rubber and cause them to wear out faster.
