How Often Should I Change MY Audi Windshield Wipers?
Ideally, you should change your Audi windshield wiper blades at least twice a year to maintain stability and the best performance. However, if you operate your vehicle in a severe climate with extreme changes in temperature and humidity, you may want to consider changing your wiper blades more often.
When your wiper blades are loose or leave streak marks, chatter or squeaks, they are past their useful life, and you must replace them immediately.
