What Causes Wiper Blade Jumping and Noise?
2 Answers
Here are the reasons for wiper blade jumping and noise: 1. Wiper damage: There are many causes for wiper blade jumping and noise, such as damaged wiper blades, grease on the windshield, or application of rain-repellent products. 2. Wiper arm deformation: It is highly likely that the wiper arm is bent, preventing the wiper blade from properly adhering to the windshield. Below is additional information related to wipers: 1. Function of wipers: Wipers, also known as windshield wipers, are devices used to remove raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. 2. Legal requirements: Due to legal requirements, almost all vehicles are equipped with wipers. Rear windows of hatchbacks and SUVs also have wipers. Apart from cars, other means of transportation such as trains and trams are also equipped with wipers. Some engineering machinery, like cranes, also have wipers installed.
I've been driving for over a decade and have experienced wiper blade chattering and noise several times. The main cause is the aging and hardening of the rubber on the wiper blades, which makes them less smooth when wiping, leading to jumping and squeaking noises. Oil film or dirt on the windshield can also cause uneven friction, especially when rainwater splashes up and forms a layer of grime on the glass. It's recommended to clean the glass first, using a dedicated oil remover or kitchen detergent to thoroughly scrub it several times. If the wiper blades are cracked or deformed, replace them with a new set, making sure to align the wiper arm pivot during installation and not to press too tightly. In winter, when the rubber becomes brittle, the problem is more pronounced, so it's best to check before the season changes. Safety-wise, chattering can blur your vision, which is extremely dangerous when driving at high speeds in the rain—don't wait until an accident happens to fix it.
