Why Do Windshield Wipers Make Noise?
2 Answers
The reasons for windshield wiper noise are: 1. The wiper blade itself is aged, deformed, or there is a foreign object between it and the windshield; 2. There is an oil film on the windshield; 3. The downward pressure of the wiper arm is not perpendicular to the windshield surface, causing friction between the wiper blade and the windshield when moving up or down, resulting in noise. The solutions for wiper noise are: 1. Replace the wiper; 2. Clean any foreign objects on or under the wiper blade to ensure the wiper area is clean; 3. Wash off dirt and grease from the windshield; 4. Adjust the angle of the wiper arm so that the wiper blade is perpendicular to the windshield. The function of windshield wipers is to remove raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and increasing driving safety.
Oh dear, as an experienced driver, I've encountered quite a few embarrassing situations with squeaky wipers! Usually, it's because the wiper blades have aged and hardened, with the rubber losing elasticity due to exposure to wind and sun, causing them to squeak when wiping. Oil stains, dust, or bird droppings on the windshield can also cause friction noise. Additionally, improper installation or looseness of the wiper arms can lead to unsteady movement. I remember the last time my car's wipers were making a terrible noise—it was winter, and they had frozen solid after being parked outside, making an awful sound against the glass. Safety is no joke; noise can distract you while driving, so it's important to address the issue promptly. I recommend checking the wiper blades monthly and replacing them if cracks are found; clean the windshield with glass cleaner; and use windshield washer fluid to moisten the blades in dry weather. Don't wait until it rains to regret not taking action, as it could damage the wiper motor. For a worry-free drive, regular maintenance is key.
