It is highly likely due to wear or deformation of the wiper rubber blade, excessive resistance of the wiper, or slight deformation of the wiper arm caused by prolonged use, resulting in a clicking noise during operation. Below is relevant information about wipers: Introduction: The wiper, also known as a windscreen wiper, is a device used to remove raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety.
