What Causes Wiper Blades to Shake and Make Noise?

Wiper blades shaking and making noise may be caused by an increased friction coefficient between the wiper and the glass surface, or it could be due to a malfunction in the wiper motor. Additional details are as follows: 1. Introduction: The wiper is an important accessory installed on the windshield, designed to remove rain, snow, and dust that obstruct visibility. Therefore, it plays a crucial role in driving safety. 2. Principle: The motor on an electric wiper drives the output shaft through a worm gear on the armature shaft and then drives the output gear via an idler and idler shaft. The output arm connected to the wiper linkage is then operated by the output shaft. When the motor rotates, the output arm and linkage are driven to move back and forth.

Last time it rained, my wipers made clicking noises and shook violently. An experienced driver told me it was mainly due to aged wiper blades—the hardened rubber had many cracks, causing uneven friction and making them skip around with squeaky sounds. If there’s oil film or insect residue on the windshield, the wipers can stick and wobble when sliding over, which is especially annoying. Installation issues are also common; if the wiper arm angle isn’t adjusted properly, uneven pressure can cause strange noises. I make it a habit to replace wiper blades every six months and always use glass degreaser when washing the car to clean the surface—don’t wait until heavy rain blurs your vision to regret it. Once, the wiper linkage was loose, causing huge vibrations, so I rushed to the repair shop to fix it. Safe driving is no joke.

Wiper blade juddering and noise are mostly caused by worn wiper blades or dirty windshield. As a DIY-savvy car owner, I regularly remove the wipers to inspect the rubber strips—replace them if there are cracks or signs of hardening. Nowadays, silicone materials are more durable and anti-judder. Oil film on the windshield should be wiped off with wiper cleaning fluid; otherwise, uneven friction can cause the wipers to jump and make noise. Aging wiper arm springs can also lead to insufficient pressure. I've tried manually adjusting the angle or spraying lubricant to reduce vibration. Replacing wiper blades is simple—buy the matching model online and install them properly following tutorials. Motor issues are rare but require professional tools to inspect the linkage. Don't delay repairs, as it can damage the windshield and compromise driving safety in rainy conditions.

The wiper judder always annoys me. Common causes include worn-out wiper blades, where hardened rubber fails to clean properly and creates buzzing noises. Dirt or scratches on the windshield can also hinder wiper movement, causing judder. I recently learned to use white vinegar while washing the car to remove oil film and reduce noise. If improperly installed, adjust the wiper arm position. It's better to replace wipers more frequently—once a year—to prevent poor visibility during rain and avoid accidents. Simple maintenance ensures worry-free driving.
