The windshield wiper and blade assembly needs to be checked on regular basis for any sort of damages, loose speedy and ravaged or frayed blade elements. Dirt can gather on the wiper blades and reduce the quality of the road film so it should be washed with a mild detergent solution. If the wiper blade elements of the wand will have cracks, wear, twists or do not clean sufficiently, they will add further ones. To replace the wiper blade assembly, one has to pull up the arm assembly so that it is out of contact with the glass, press upwards on the release lever and sliding the wiper blade assembly out of the hook positioned at the end of the arm. Subsequently, connect the new wiper to the arm and make certain that it stays in place because you will hear a click.
