What Are the Reasons for Noisy Wiper Blades?
2 Answers
Noisy wiper blades can be caused by: 1. Aging or deformation of the wiper blade itself, or the presence of foreign objects between the blade and the windshield; 2. The existence of an oil film on the windshield; 3. The downward pressure of the wiper arm not being perpendicular to the windshield surface, causing friction and noise when the blade moves up or down. Solutions for noisy wiper blades include: 1. Replacing the wiper blades; 2. Cleaning any foreign objects under or on the wiper blade to ensure the area is clean; 3. Washing away dirt and grease from the windshield; 4. Adjusting the angle of the wiper arm so that the blade is perpendicular to the windshield. The function of wiper blades is to remove rain and dust from the vehicle's windshield, improving the driver's visibility and enhancing driving safety.
As a veteran driver with over 20 years of experience, I've encountered wiper noise issues countless times. The most common cause is hardened rubber blades due to aging, especially when they lose elasticity after sun exposure, creating squeaky sounds during operation. Windshield oil film is particularly annoying too - it traps dust during rain, creating a sandpaper effect that makes wipers skip. Once my wiper arm's spring loosened, causing uneven pressure that made the entire rubber blade wobble like dancing. Remember never to operate wipers dry - scraping without washer fluid severely damages the blades. When noise occurs, first check for blade cracks, then clean the windshield with medical alcohol to remove oil film. If problems persist, adjust the wiper arm angle. It's best to replace the entire set before rainy season - safety comes first.
