What to Do When Wiper Blades Make Glass Scraping Noise?
2 Answers
Solutions for wiper blades making glass scraping noise: 1. Replace the rubber blade; 2. Spray windshield washer fluid before use; 3. Clean the wiper blades regularly. This issue may occur due to deformed wiper blades, aged rubber blades, or contaminated glass with debris. However, wiper blade deformation is rare, and if this problem occurs, it should be replaced at a 4S shop. Wiper blades are sheet-like structures installed in front of the windshield, consisting of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly, mainly used to clear rain, snow, and dust that obstruct the view on the windshield.
I've been driving for many years and often encounter the issue of wiper blades squeaking on the windshield. This noise is mostly caused by a dirty windshield or oil film, such as when parked under trees or with bird droppings left uncleaned. I usually start by thoroughly washing the windshield with warm water and dish soap, using a microfiber cloth to scrub off the dirt and ensure no residue remains. If that doesn't work, I check the wiper blades: if the rubber is aged, cracked, or has gaps, I replace them with new ones; if undamaged, I clean the blade strips with alcohol to restore their elasticity. During installation, I press them gently to ensure they adhere tightly to the windshield. These minor fixes are quick and easy to do yourself—after all, how dangerous is it to have poor visibility during rain or snow? Timely maintenance is crucial to prevent accidents.
