Rear Windshield Wiper Blade Change: 2021 Cadillac XT4 Premium Luxury 2.0L 4 Cyl. Turbo

Learn how to remove the rear wiper blade in your 2021 Cadillac XT4. Replace the rear wiper blade on your XT4 at least once a year even if you don't use your wiper much - the sun wears out the wiper wiper blade rubber more than using it to wipe water. Another trick to enhance the longevity of your XT4's wiper blade is to scrape off the ice and snow from the glass or use the defroster before using your wiper. A layer of ice has sharp edges that can reduce the effectiveness of the micro edge of the rubber wiper blade.
