Why Do Windshield Wipers Make Noise?
2 Answers
Windshield wipers make noise due to the following reasons: foreign objects on the windshield; damage to the wiper linkage mechanism; incorrect wiper angle; friction in the wiper linkage bushing. Solutions for noisy windshield wipers: Use windshield washer fluid to clean the windshield; regularly clean or replace wiper blades; replace linkage mechanism components; adjust the wiper angle. Function and types of windshield wipers: Windshield wipers are devices that sweep away rain and dust from the vehicle's windshield, improving driver visibility and enhancing road safety. Types of wipers include traditional intermittent wipers and rain-sensing wipers.
I'm always troubled by the squeaking sound of my wipers, mainly due to aging wiper blades. After about six months of use, the rubber on the blades starts to harden and crack, causing a squeaking noise when wiping the windshield. Dirty windshields are another common cause—like when I park under trees, dust and insect residue accumulate, forming an oily film that increases friction. Dry weather or leftover car wash residue after cleaning can make it worse. Never wipe dry; always use enough washer fluid for lubrication. Improper wiper arm adjustment can also cause noise—too tight creates loud pressure sounds, while too loose causes bouncing and uneven wiping. Once, I found that adding lubricant to a rusty wiper frame fixed the issue. Preventive measures are simple: clean the wipers and windshield with a damp cloth monthly, and replace the blades before the rainy season for safety and peace of mind—don’t wait until they stop working properly.
