Wiper and blade assembly to the windshield and rear window should be checked after some time in case of damage, loose parts, and broken or worn parts of the blades. The road film may be deposited on the wiper blades, which can influence its performance, thus they need to be cleaned on a regular basis using mild detergent solution. When cleaning the wipers, the wiping mechanism can loosen the bolts, nuts and fasteners and these must be checked and tightened where needed, when inspecting the wipers, swing the wiper arm out and then turn the arm and trim cover toward the glass. The wiper blade elements should be replaced in case they are broken, old fashioned, or damaged. When changing the blade assembly, raise the arm assembly off the glass so that it is clear, press the release lever, and press it down the arm. Use needle nose pliers to squeeze the retaining clip and slide the blade element out and then put the new blade element in and snap the retaining clip in place after which the blade assembly is mounted on the wiper arm.
