Why Do Windshield Wipers Make Squeaky Noises?

[AdrianAnn]

The following are the reasons why windshield wipers make squeaky noises: 1. Worn-out wiper blades: Wiper blades are made of rubber and will harden and wear out over time, especially in winter. If they no longer clean effectively, the simplest solution is to replace them. Generally, wiper blades should be replaced every one to two years. 2. Debris on the wiper blades: When the wipers are turned on, sharp noises may occur due to friction between the blades and the windshield. Check and remove any debris on or under the wiper blades to ensure they remain clean. 3. Incorrect wiper arm angle: This can cause the blades to bounce on the windshield, leading to noise. If the blades are in good condition, adjust the wiper arm angle so the blades are perpendicular to the windshield. You can use pliers wrapped in a cloth to gently bend the wiper arm for proper alignment. 4. Linkage mechanism deformation: Deformation of the linkage mechanism, motor issues, relay problems, or long-term wear and tear (rust, jamming, etc.) can also cause noise. If you've recently replaced the wiper blades, check for dirt or oil residue on the windshield. Clean the glass with a cleaning solution or try a new set of wiper blades.
