Why Does the Wiper Shake?

[BeckettLynn]

The wiper shaking is caused by issues with the wiper blade itself or foreign objects trapped between the wiper blade and the windshield. Below are the reasons for wiper shaking and their solutions: Foreign objects trapped between the wiper blade and the windshield causing shaking: When the wiper is turned on, a sharp friction noise may occur between the wiper blade and the windshield. The owner can check and clean any foreign objects present on the wiper blade or underneath it. Wiper linkage bushing friction causing shaking: Over time, the wiper linkage mechanism may age, the spring elasticity of the wiper arm may decrease, and the bushing may wear out or even fall off. Please inspect the wiper arm or the linkage bushing. Wiper motor causing shaking: If the wiper motor itself lacks sufficient power and shakes, it may be a sign that the motor is nearing the end of its lifespan. It is recommended to visit a professional repair shop for a more detailed inspection. Solutions: Wiper blades are rubber products and will harden and age over time, especially in winter. If the wiper no longer cleans effectively, the simplest and most effective solution is to replace the wiper blade directly. Generally, it is recommended to replace wiper blades every one to two years. Ensure the wiper blade area is kept clean.

A seasoned driver like me can tell the problem just by the wiper's vibration. Most likely, the wiper blade has aged, and the deformed rubber can't grip the glass properly, causing hard vibrations. Another possibility is oil film or dust on the glass surface, making the wiper blade slip and become unstable. In more severe cases, rust on the linkage or misalignment during installation can worsen the shaking. If this happens while driving, pull over immediately—blurred vision in the rain can lead to serious accidents. I recommend regularly cleaning the glass with a neutral detergent to remove oil film; wiper blades should ideally be replaced every six months to a year, and a sub-100-yuan frameless model is quite durable. Also, always check the tightness of the screws—don’t overlook this detail, as proper maintenance can save a lot on repair costs.

My wiper blades keep shaking, which is really annoying. The same thing happens with my car. After searching online, I found out it might be due to incorrect wiper arm angle or uneven pressure. I tried adjusting the position myself, but it didn't work. Eventually, I went to a repair shop, and the technician said I needed new blades. They explained that when the rubber on the wiper blades hardens or gets tree sap stuck to it, they tend to "dance." After replacing them, they worked smoothly right away, and it wasn't expensive—just a few dozen yuan. Shaking wipers during rain can be dangerous, making it hard to see the road and increasing the risk of rear-end collisions. I also picked up a handy tip: after washing the car, wipe the wiper arms with a cloth to prevent rust. Developing this habit has made things much easier, and I don’t have to worry when driving on the highway.

Wiper blade judder is mostly caused by aging of the blade surface or wear at the support points. For standard blades, hardened rubber loses grip on the glass, causing vibrations; it could also be due to uneven pressure in the linkage system. Oil residue or fine sand on the windshield exacerbates the issue. From my observation, replacing with new blades usually solves it – silicone-based options provide better anti-judder performance. During routine maintenance, clean the windshield surface using neutral detergents. Though a minor issue, it affects visibility safety, so address it early to prevent developing bad habits.
