What Causes the Noise When the Wiper Blades Are Operating?

[DiDaniela]

Noise from the wiper blades may be caused by aging of the wiper blades, foreign objects between the wiper blades and the windshield, or damage to the wiper linkage mechanism. Here is some relevant information: 1. Wiper blade aging: Wiper blades are made of rubber, and prolonged exposure to sunlight, wind, and rain can easily lead to aging issues. Generally, the lifespan of wiper blades is about one to two years. If the noise is due to aging, the wiper blades need to be replaced. Currently, silicone-coated wiper blades are popular in the market. Compared to rubber, silicone is less prone to aging and has a longer lifespan, so they can be considered when replacing wiper blades. 2. Foreign objects: This is also a common issue, mainly involving small debris like sand or other particles. Not only can this cause noise, but it may also scratch the windshield. In such cases, simply removing the foreign objects will resolve the problem.
