Q: How should windshield wiper blade elements be inspected and replaced?
A: Periodically check the windshield wiper blade component for breaks and wear. Lift the wiper blade assembly off the glass. Squeeze both the release tabs of the wiper blade together and rotate outwards, unhooking the blade from its arm. Compare new blades to old ones for length, design, etc. Reverse all of this to install a new blade. Make sure that you properly fasten your wiper blade, then wet your windscreen in order to test for proper operation.
