Why Does the Wiper Make Noise?
2 Answers
Reasons for wiper noise are as follows: 1. Wiper aging: The wiper is made of rubber, and prolonged exposure to sunlight, wind, and rain can easily cause aging issues. Generally, the lifespan of a wiper is about one to two years. If the noise is due to aging, the wiper needs to be replaced. 2. Foreign objects between the wiper and the windshield: This issue is also quite common, mainly caused by small sand particles or other debris. Not only can it cause noise, but it may also scratch the windshield. In this case, simply removing the foreign objects will solve the problem. 3. Damage to the wiper linkage mechanism: This type of fault code issue arises when the motor, linkage mechanism, or other components malfunction, rust, or deform, all of which can lead to noise and other problems.
I find that most wiper noises are caused by issues with the wiper blades. Over time, the rubber hardens due to aging, creating friction against the glass and producing squeaking sounds. Another common reason is oil film or insect residue on the windshield, which leads to incomplete wiping and increased noise. Sometimes, improper installation or looseness of the wiper arm causes vibration in the wind, amplifying the sound. To fix this, first thoroughly clean the glass and wiper blades with a glass cleaner to maintain a clean surface. If the noise persists, replace the wiper blades before they completely fail. Regular inspection of wiper blade condition is crucial—replacing them every six months can prevent problems. Driving in the rain with noisy wipers is not only annoying but also distracting, so early intervention is safer. Parking in the shade to avoid direct sunlight can also extend the lifespan of wiper blades.
