Why is there noise from the wiper?

[LeVivian]

Car wiper noise may be caused by the following reasons: 1. Wiper blade issues causing noise: Wiper blades are rubber products that may harden or age after prolonged use, especially in winter. If they no longer clean effectively, the simplest solution is to replace them with new blades. Generally, wiper blades should be replaced every one to two years. 2. Foreign objects between the wiper blade and windshield causing noise: When the wiper is activated, sharp friction sounds may occur between the blade and windshield. Owners should check and remove any debris from the wiper blade or underneath it to ensure cleanliness. 3. Noise from wiper linkage bushing friction: Over time, the wiper linkage mechanism may age, the wiper arm spring may lose elasticity, and the bushing may wear out or even fall off. Please inspect the wiper arm or linkage bushing.
