Why do your wiper blades lift off of your windshield when you are driving?

This is called "windlift" and is usually more of a problem with conventional framed wiper blades. Bottom-line, its a result of the design of the wiper where airflow actually can get under the wiper and lift it rather than a design that uses the air to actually push the wiper down and create more contact.

If you are experiencing this on your vehicle, I recommend looking into the newer-style beam wiper blades that have aerodynamic designs that counteract windlift. Checkout the related links and you'll be fully schooled in the latest wiper blade technologies.

I use both Trico NeoForm Beam Blades and Trico Tech Beam Blades and have no problems with windlift and also enjoy the many other benefits to the new technologies.
