Why Do Windshield Wipers Always Make Noise When Wiping?
3 Answers
Windshield wipers always make noise when wiping due to the following reasons: Wiper Aging: The material of wipers is rubber, which is prone to aging after prolonged exposure to sunlight, wind, and rain. Generally, the lifespan of wipers is about one to two years. If the noise is caused by aging, the wipers need to be replaced. Currently, silicone-coated wipers are popular in the market. Compared to rubber, silicone is less prone to aging and has a longer lifespan, so it can be considered when replacing wipers. Foreign Objects Between the Wiper and 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. Damage to the Wiper Linkage Mechanism: This type of problem occurs when components such as the motor or linkage mechanism malfunction, rust, or become deformed, all of which can lead to noise and other issues. In such cases, it is necessary to visit a repair shop for professional inspection and repair. Another possible cause is the angle of the wiper arm, which also requires adjustment by a professional.
As a veteran driver with twenty years of experience, I often encounter the annoying squeaking sound of wiper blades on the windshield. This is mostly caused by aged wiper rubber strips or a layer of oil film accumulated on the glass. Think about it: over time, wiper rubber strips harden, become brittle, and lose elasticity, causing noise when rubbing against the glass. If the glass surface isn’t clean—such as when covered with dust or bug residue—it’s like sandpaper scraping against it. Another common reason is turning on the wipers directly in dry weather without spraying windshield washer fluid first, leading to dry wiping and noise. My own lesson is to regularly clean the windshield with dedicated glass cleaner and replace the wiper blades once a year. Don’t skimp by buying cheap ones, as they can easily scratch the glass. Squeaky wipers while driving are not only irritating but also obstruct visibility, especially during rainy night drives. Safety comes first—address the issue promptly and don’t delay.
I'm the type of car owner who pays great attention to maintenance. When I first bought the car, the wipers kept making noise. Later, I figured out the reasons: first, the wiper rubber blades had worn out. After exposure to wind and sun, the rubber hardened, making a sound like scraping plastic when in use. Additionally, oil film or uneven dust on the windshield, such as bird droppings when parked under a tree, can cause noise. Improper installation could also be a factor; incorrect angle or tightness of the wiper arm leads to uneven contact between the blade and the glass. Now I've developed a habit: every time I wash the car, I thoroughly clean the windows with dish soap or automotive glass cleaner, avoiding dry use by spraying water before activating the wipers. If that doesn't help, I replace them with new wipers, opting for softer rubber ones. Daily maintenance is quite simple. Minor wiper issues can be annoying, while major ones can affect driving safety. Don't overlook these small details.
