What Causes the Wiper Motor to Make Noise?

[LeahDella]

There are primarily three reasons for the phenomenon where the wiper does not move but makes a buzzing sound: 1. The first reason is that the vehicle's windshield is not clean enough; secondly, the wiper blades have reached the end of their lifespan and can no longer be used; finally, the spring strength of the wiper gradually weakens as the vehicle ages. By troubleshooting the wiper based on these three reasons, the issue can generally be resolved; 2. If the driver notices the wiper scraping against the windshield or jumping during rainy weather, it is essential to find a sheltered spot to park the vehicle immediately. Avoid driving onto elevated roads or highways while enduring the annoyance. After parking, the first thing to check is not the wiper but the windshield; 3. So, how can the issue of a 'dirty film' on the windshield be resolved? It's actually not very difficult, but drivers need to adopt a habit of 'regular maintenance.' Regardless of how often the car is washed, to prevent the formation of a 'dirty film' on the windshield, it is best to clean the windshield with water once a week. In areas with severe air pollution, drivers can add an appropriate amount of alkaline cleaner to the water.
