The windshield wiper and blade assembly ought to be checked at a certain period of time in relation to its damages, dislodged parts and broken or worn blade parts. The wiper blades may accumulate road film on them and this may interfere with their efficiency, and hence should be cleaned frequently using mild solution of detergent. When the wiper blade parts are broken, damaged, deformed, or no longer clean, then it is preferred that they are changed to other new ones. To change the wiper blade, make space by lifting the arm assembly away off the glass, pressing the release lever then sliding the wiper blade assembly off the hook at the end of the arm. In order to detach the blade holder, push the release pin and tug the wiper blade away against the direction of the arrow to disconnect it with the arm. Lastly, place the new wiper into the arm making sure that you hear an audible clicking sound.
