Periodically, check the windshield wiper and blade assembly for harm, loose parts, as well as cracked or worn blade components. Film coating can collect on the wipers and compromise their efficacy; hence they should be cleaned using a mild detergent solution. The action of wiping may loosen bolts, nuts, and fasteners; therefore, it is advisable to tighten them whenever blades are checked. Replace them if the blade elements are cracked, worn out or bent and no longer clean properly. Take away the arm assembly from the glass so that it does not touch anything when being released then push down on the release lever while sliding off the wiper blade assembly from its hook at the tip of the arm. At this point insert can be installed into arm as well as removing it out by just pulling one end of it out with your fingers for replacement purposes alone. Attach now one of these blades to an arm whereby connection will be demonstrated through hearing a click sound as a confirmation.
