Why does the wiper keep making noise?

[LeAyla]

There are several reasons why the wiper keeps making noise: 1. Fine streaks, fog, or linear residues appear on the glass. Foreign objects are attached, such as sand particles or dust on the triangular edge, or the edge is damaged. Clean the edge or replace the wiper blade. 2. The swing is not smooth, and the wiper jumps abnormally. The edge of the wiper blade is bent or wavy, or there are residues like wax or oil film on the glass surface. Wipe the glass clean or replace the wiper blade. 3. The contact surface of the rubber cannot fully adhere to the glass surface, resulting in wiping residues. After prolonged use, the rubber hardens, loses elasticity, or becomes damaged. Replace the wiper blade. 4. The glass surface shows a water film state after wiping. The wiper arm is deformed due to rust or external force. Replace the wiper.
