What Causes the Wiper Blade to Make Noise When Wiping the Windshield?
2 Answers
The reasons for the wiper blade making noise when wiping the windshield are as follows: 1. The wiper blade has aged. Solution: Replace the wiper blade with a new one. Generally, it is recommended to replace wiper blades every one to two years. 2. There is debris stuck in the wiper blade. Solution: Inspect and clean the wiper blade or remove any debris underneath it. 3. Incorrect installation angle of the wiper arm. Solution: Place a cloth under the head of the wiper arm to ensure the wiper blade is perpendicular to the windshield. 4. Abnormal movement caused by deformation, jamming, or rust in the linkage mechanism. Solution: It is recommended to clean the windshield with a cleaning solution or replace the wiper blade with a new one.
I've driven multiple cars, and squeaky wipers are quite common, mainly due to aging or damaged wiper blades. The rubber material hardens and becomes brittle over time, causing a screeching sound when wiping the glass, which is more noticeable in summer or winter. Another reason is the buildup of oil film or dust on the windshield surface, affecting smooth sliding. Neglecting regular cleaning, such as bird droppings or insect remains sticking to the glass, can also increase friction noise. I recommend spraying some windshield washer fluid to moisten the blades before driving each time, avoiding dry wiping that damages the rubber and creates noise. If the noise is loud and accompanied by poor wiping, it's time to check the lifespan of the wiper blades—generally, they should be replaced every six months. When replacing, opt for high-quality synthetic rubber blades for durability and performance. If the noise persists after replacement, it might be due to improperly installed wiper arms or uneven pressure, causing uneven wear—just have a professional shop adjust them. Regularly checking the wiper system during maintenance can save a lot of trouble.
