How to Solve Wiper Blade Chattering?
2 Answers
The causes and solutions for wiper blade chattering are as follows: 1. Wiper blade issues causing chattering: Wiper blades are rubber components that harden and age over time, especially noticeable in winter. The simplest and most effective solution is to directly replace the wiper blades. Generally, it is recommended to replace wiper blades every one to two years. 2. Foreign objects between the wiper blade and windshield causing chattering: When the wiper is activated, a sharp friction noise may occur between the blade and the windshield. Owners should check and clean any debris on or under the wiper blade to ensure the blade area is clean. 3. Wiper linkage bushing wear causing chattering: In older vehicles, the wiper linkage mechanism may age, the wiper arm spring may lose elasticity, and the bushings may wear out or even fall off. Please inspect the wiper arm or linkage bushings. 4. Wiper motor causing chattering: If the wiper motor itself lacks power and causes chattering, this may indicate the motor is nearing the end of its lifespan. It is recommended to have a more detailed inspection at a professional repair shop.
Wiper blade chattering is indeed a headache, and I've experienced it several times. The common cause is oil or dust on the windshield, preventing the blade from sliding smoothly. It's recommended to thoroughly clean the glass surface with a glass cleaner, paying attention to even the hard-to-reach corners, especially after rain when dust tends to accumulate. Another factor is aging or deformed wiper blades—over time, the rubber hardens and curls. Replacing them with new blades usually solves the problem, and they're affordable, costing just a few dozen yuan. Sometimes, the wiper arm angle is misaligned; you can adjust the screw position at the joint yourself—loosen it with a wrench, align the angle, and then tighten it. I always check before heavy rain, as prevention is much simpler than post-failure repairs.
