What Causes Excessive Noise from Windshield Wipers?
1 Answers
The reasons for excessive noise from windshield wipers are as follows: 1. Aging wiper blades or foreign objects on the glass: Wiper blades are made of rubber, and prolonged parking in open environments can cause them to age. Aged wiper blades will not clean the windshield properly and may leave streaks of water. In this case, simply replace the wiper blades. Additionally, if the windshield accumulates sand or dirt in an open environment, the wipers may produce noise when moving across the glass. 2. Wiper blades being too soft or improperly adjusted: When replacing wiper blades yourself, the wiper arm and the underlying mechanism may shift, preventing the wiper blade from returning to its lowest point when moving downward or causing it to hit the A-pillar when moving upward. In this situation, loosen the fixing nut of the wiper arm and adjust it to the correct position. 3. Noise from the wiper motor and linkage mechanism: Always use windshield washer fluid before activating the wipers. Besides helping to clean dust more effectively, it also reduces the friction resistance of the wiper blades on the glass. Prolonged dry wiping can place excessive load on the wiper motor and linkage mechanism, leading to motor damage or loosening of the linkage, which can cause noise.
