Why is there noise when the wiper wipes the windshield?
2 Answers
There are three main reasons why the wiper makes noise when wiping the windshield: 1. Wiper blade aging or foreign objects on the windshield: This is a common cause of noise when the wiper wipes the windshield. Wiper blades are made of rubber, and long-term exposure to outdoor conditions such as wind, rain, and sunlight can easily cause them to age. Aging wiper blades will not clean the windshield effectively and may leave streaks of water. In this case, simply replace the wiper blades. 2. Wiper blades are too soft or improperly adjusted: When replacing wiper blades yourself, it may cause the wiper arm and the underlying mechanism to shift, preventing the wiper blade from returning to the lowest point when moving downward or hitting the A-pillar when moving upward. In this case, loosen the fixing nut of the wiper arm and adjust it to the proper position. 3. Noise from the wiper motor and linkage mechanism: Always spray water before using the wiper. Besides better cleaning dust, it also reduces the friction resistance of the wiper blade on the windshield. Prolonged dry wiping can increase the load on the wiper motor and linkage mechanism, leading to motor damage or loosening of the linkage mechanism, resulting in noise.
As a veteran driver with 20 years of experience, let me tell you, strange noises from windshield wipers are extremely common and usually not a serious issue. The main causes are aging or hardened wiper rubber blades – the rubber becomes brittle after prolonged exposure to sun and wind, creating squeaking sounds when rubbing against the glass. Poorly cleaned windshields can also cause trouble, such as oil film or dust buildup increasing friction. Weather plays a role too; rubber hardens in cold winter temperatures, making the scraping noise more pronounced. Prevention is straightforward: replace wiper blades regularly (once a year suffices); spray washer fluid before rain to reduce dry wiping risks; routinely clean the windshield with neutral detergent to remove grease. If new wipers still make noise, check if the wiper arm pressure is even – loose or damaged springs can cause uneven wiping. In short, don’t ignore this problem. Addressing it promptly ensures clear visibility and driving safety – spending a little money on repairs is worth it.
