When driving a car, the wiper isCrashbashnintendoswitchWe rely very much on an accessory that keeps the windshield clean so that drivers can clearly see the road ahead. However, sometimes we find that the wiper will make a noise when scraping the glass, which will not only affect the driver's mood, but also affect the service life of the wiper. So what is the reason why the wiper makes a noise when scraping the glass?

First of all, the aging of wipers is the most common reason. After the wiper has been used for a period of time, the rubber strip will be worn and aged, resulting in a lack of close contact with the windshield, resulting in a noise. In this case, the problem can be solved by replacing a new wiper.

Secondly, the uneven surface of the windshield may also cause the wiper to make a noise when scraping. If there are protuberances, depressions or oil films on the surface of the windshield, it will lead to uneven contact between the wiper and the windshield, resulting in noise. In this case, you can use a professional cleaner to clean the windshield, or use sandpaper to polish the uneven area to restore its original flatness.

In addition, improper installation of the wiper may also cause noise when scraping. If the spring pressure of the wiper is too high or too small, or if the installation position is not accurate, it may cause noise during wiping. In this case, it is necessary to re-adjust the installation position of the wiper or replace the appropriate spring to ensure closer contact with the windshield.

In addition to the above reasons, weather factors may also cause the wiper to make a noise when scraping. In a low temperature environment, the rubber strip of the wiper may harden, resulting in a lack of contact with the windshield, resulting in noise. In this case, the wiper suitable for low temperature environment can be replaced, or the wiper rubber strip can be smeared with antifreeze to improve its flexibility.

The possible cause of the problem is the solution to the problem. The wiper makes a sound when scraping. The wiper is aged and replaced. The windshield surface is uneven when the new wiper is scraped. Clean the windshield with professional cleaner. Or use sandpaper to grind uneven areas and make a sound when the wiper is installed improperly, or when changing a suitable spring wiper, the weather factor changes the wiper suitable for low temperature environment, or apply antifreeze on the wiper rubber strip.

Generally speaking, there are many reasons for the noise when the wiper scrapes the glass, which needs to be analyzed and dealt with according to the specific situation. If the problem persists, it is recommended to go to a professional car maintenance shop for inspection and maintenance in time to ensure driving safety.
