What Causes the Squeaking Noise of Windshield Wipers?
2 Answers
Windshield wipers produce squeaking noises due to issues with the wipers themselves, foreign objects between the wiper box and the windshield, or deformation of the linkage mechanism. Issues with the wipers themselves: Wiper blades are made of rubber and can harden or deteriorate over time, especially in winter. If they no longer clean effectively, the simplest and most effective solution is to replace them. It is generally recommended to change wiper blades every one to two years. Foreign objects between the wiper box and the windshield: When the wipers are activated, sharp noises may occur due to friction between the wiper blades and the windshield. Drivers should inspect and clean any debris under or around the wiper blades to ensure they remain clean. Deformation of the linkage mechanism: Deformation of the mechanism or issues with the motor or intermittent relay (such as erratic speed or continuous operation) can also cause unusual noises. Other factors include prolonged use, rust, or mechanical deformation. If the wiper blades are new, check for dirt or oil residue on the windshield and clean it with a cleaning solution or try another set of blades. If the noise persists, adjust the angle of the wiper arm using pliers or similar tools.
I've also experienced the squeaky friction sound from windshield wipers while driving, which is really annoying, especially on rainy days when it becomes distracting. The main reasons are usually the aging and drying of the wiper rubber, which loses elasticity and causes friction against the glass. Or there might be oil stains or insect residues on the glass surface, increasing friction. Sometimes, improper installation or misalignment of the wipers can also cause noise. I suggest first trying to clean the glass and wiper blades with dish soap or a specialized cleaner—it might just solve the problem. If the noise persists, you might need to replace the wiper blades, which cost just a few bucks for a pair on Taobao. If left untreated, it could even scratch the glass, leading to more expensive repairs. I check my wipers every six months to prevent small issues from becoming big problems. Regular car maintenance is essential to keep it in good condition for safe and comfortable driving. Don’t forget that wiper blades also need lubrication, but avoid using overly oily substances, as they attract more dust.
