Reasons for the noise when the wiper of a new car scrapes the windshield: 1. Foreign objects on the windshield: In an open-air environment, the windshield may accumulate sand or dust, and the sand particles scraping the glass under the movement of the wiper can cause noise; 2. The wiper rubber is too soft or improperly adjusted; 3. Noise from the wiper motor and linkage mechanism: Prolonged dry wiping of the windshield puts a heavy load on the wiper motor and linkage mechanism, which can lead to motor damage or loosening of the linkage mechanism, resulting in abnormal noise. The wiper is a device used to remove raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. The wiper assembly includes a motor, reducer, four-bar linkage mechanism, wiper arm spindle, and wiper blade assembly.
I just bought a new car a few days ago, and the wipers keep squeaking when wiping the windshield, which is quite annoying while driving. Possible causes include dust, dead insects, or residual protective film from manufacturing left on the windshield surface; although the wiper blades are new, the rubber material may not have adapted to the weather, becoming stiff and losing proper contact; misalignment during installation can also cause uneven pressure and friction noise. Additionally, prolonged storage of new cars often leads to rubber aging or minor glass wear. I’d like to remind everyone: if your new car has this issue, don’t rush to the dealership—first, thoroughly clean the windshield and wiper blades with warm water and mild detergent, then manually adjust the pressure. The noise isn’t just irritating; it could also affect visibility, so extra caution is needed when driving in rain. Preventive measures like regular windshield cleaning are highly recommended.
