Wiper Blades Occasionally Make Squeaking Noise on Windshield

[Carson]

Reasons for wiper blades making abnormal noises when wiping the windshield: 1. Worn wiper blades: Wiper blades are rubber products that harden and deteriorate over time, especially noticeable in winter. If they no longer clean effectively, the simplest solution is to replace them. Generally, wiper blades should be replaced every 1-2 years. 2. Debris between wiper blades: Sharp friction noises may occur if foreign objects are trapped between the blades and windshield. Check and clean the blades or remove any debris beneath them. 3. Incorrect wiper arm angle: If the wiper arm is improperly aligned, the blade may jump on the windshield, causing noise. Adjust the arm so the blade sits perpendicular to the glass. 4. Linkage mechanism issues: Deformation of the linkage, motor problems, relay malfunctions, or long-term wear (rust, jamming, or misalignment) can also cause noise. For newly replaced blades, check for dirt or oil residue on the windshield and clean it with washer fluid if needed.
