What Causes the Windshield Wiper to Make Noise?
2 Answers
Reasons why windshield wipers make noise: 1. Foreign objects on the wiper: If there are foreign objects between the wiper blade and the windshield, it not only causes a squeaking noise when wiping the glass but also significantly affects the wiping effect, posing a potential safety hazard. Therefore, after driving through rough road conditions, it's best to check the wiper for any foreign objects and clean them promptly if found. 2. Quality of the wiper: Poor-quality wipers often have rubber components that lack good resistance. Under prolonged exposure to sunlight, they can easily harden (become rough), leading to squeaking noises during operation. In this case, simply sanding the blade smooth with sandpaper can resolve the issue. 3. Wiper angle: An incorrect angle can cause the wiper blade to jump on the windshield, resulting in noise. The owner can adjust the angle themselves. However, avoid applying too much downward pressure on the wiper, as this can accelerate windshield wear.
As someone who frequently handles vehicle maintenance, I find that the reasons for wiper blades squeaking on the windshield are quite common: the main cause is aging or deformation of the wiper blades. Over time, the rubber hardens, leading to uneven wiping and squeaking. If there is an oil film or dust stains on the glass surface, rainwater mixing with these contaminants creates friction points, amplifying the noise. Another reason could be improperly secured wiper arms or weakened springs, causing uneven pressure and resulting in jumping noises during operation. I recommend using a windshield cleaner to thoroughly clean the glass during dry weather. If the noise persists, replace the wiper blades immediately to avoid further complications. Seasonal changes have a significant impact—cold winters make the wiper blades harder, leading to more frequent noise. Therefore, don’t delay addressing this issue, as it can affect driving visibility.
