What Causes the Sound When Car Wipers Scrape the Windshield?
1 Answers
Reasons for the sound when car wipers scrape the windshield: 1. Aging of the wiper causes the rubber part to wear or fall off, resulting in abnormal noise due to friction during the wiping process. This is a normal phenomenon, and it can be resolved by timely replacement; 2. If there is no water on the windshield during wiper use, leading to insufficient lubrication, abnormal noise may occur; 3. The presence of hard impurities such as sand or stones on the windshield can also cause abnormal noise due to friction during wiper operation. Larger impurities on the windshield need to be cleaned off; 4. Damage to the wiper linkage mechanism. In this case, it is necessary to visit a repair shop for professional repair or directly replace the wiper with a new one.
