Rear Windshield Wiper Blade Change: 1999 BMW 540i 4.4L V8 Wagon

Learn how to remove the rear wiper blade in your 1999 BMW 540i. Replace the rear wiper blade on your 540i 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 540i'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.
