What causes the squeaking sound when new car wipers scrape the windshield?
2 Answers
The reason for the squeaking sound when new car wipers scrape the windshield is insufficient lubrication from the windshield washer fluid, and it is recommended to add more washer fluid. If the wiper blades are worn, have an uneven friction surface, or are deformed, it is advisable to replace the wiper blades. If the spring on the wiper arm is too tight, the solution is to slightly stretch the spring, and the noise will naturally decrease over time. Wipers, also known as windshield wipers or wiper blades, are devices used to remove raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. Due to legal requirements, almost all cars are equipped with wipers.
I've encountered this issue several times where the new car's wipers squeak loudly when wiping the windshield. Generally, new windshields come with a protective coating or residual transport film from the factory, causing the wiper rubber to slip and dance, producing noise. First, thoroughly clean the windshield with glass cleaner, especially those water stain marks left after rain. Another possibility is incorrect wiper blade installation angle or uneven pressure, preventing the rubber from tightly adhering to the glass—try adjusting the wiper arm angle yourself. Rubber quality also matters; some new car blades are initially too stiff and need breaking in, often improving after a week or two of use. If the problem persists, have the dealership replace them with genuine wiper blades—never attempt sanding them as it may impair visibility. Don't worry if your new car has this issue; it's usually easy to fix.
