Nissan 28890-ZR81A Window Wiper Blade Assembly

This assembly should also be checked occasionally for signs of damage or malfunction, loose parts, and signs of fine cracks on the blade elements of the wiper and blade. Road film tends to collect on the wiper blades and impact their performance; therefore, they should be cleaned with mild detergent from time to time. The wiping mechanism action can cause the loosening of bolts, nuts and fasteners, it's necessary to inspect and if needed, tighten all the bolts which should also check wiper blades. If the elements of the wiper blade are chattered, worn, or built-in incorrectly or do not clean effectively, they should be replaced by the new ones. For the wiper blade assembly removal, first lift the arm assembly off the glass, pull down on the release lever and remove the assembly by unlocking it from the hook at the end of the arm. By using the needle-nose pliers one needs to compress the blade element then pull it out from the frame then dispose it, after that one needs to slide the new element in until the fingers of the bladed assemblies lock into the notches of the wiper element. Installation is the exact opposite of removal.
