What Causes the Noise When Wipers Scrape the Windshield?
1 Answers
The reasons for the noise when wipers scrape the windshield are: 1. Wiper blades are made of rubber, which hardens and ages over time; 2. The wiper blades have not been in contact with water for a long time, making them dry; 3. There is debris between the wiper blades and the windshield; 4. The motor and intermittent relay affect the speed, causing friction if the movement is too fast or too slow; 5. The angle of the wiper arm is incorrect, causing the wiper blade to move irregularly on the windshield and produce noise. Solutions include: 1. Replacing the wiper blades; 2. Cleaning between the wiper blades and windshield; 3. Readjusting the position of the wiper arm. Wipers enhance driving safety during rainy weather. If there are issues with the wipers, it is recommended to repair them promptly to avoid accidents.
