What Causes Wiper Blades to Shake and Make Noise?
2 Answers
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.
