Solutions for wiper blade chatter are as follows: 1. Foreign objects between the wiper blade and windshield causing chatter: When the wiper is activated, a sharp friction noise may occur between the wiper blade and windshield. The owner can check and clean any foreign objects present on the wiper blade or underneath the wiper to ensure the wiper area is clean. 2. Wiper linkage bushing friction causing chatter: Over time, the wiper linkage mechanism may age, the wiper arm spring's elasticity may decrease, and the bushings may wear out or even fall off. Please inspect the wiper arm or linkage bushings. 3. Wiper motor causing chatter: If the wiper motor itself lacks sufficient power and chatters, it may be a sign that the motor is nearing the end of its lifespan. It is recommended to have a more detailed inspection at a professional repair shop.
