What Are the Causes of Wiper Noise?
2 Answers
Wiper noise can be caused by impurities on the glass surface, aging wiper blades, improper contact surface, or excessive clearance in the wiper blade connecting shaft. There are four maintenance methods for wipers: 1. When using wipers on sunny days, spray windshield washer fluid and avoid dry wiping: When using wipers to remove dust from the windshield on sunny days, always spray windshield washer fluid and avoid dry wiping. 2. Manually remove stubborn or hard contaminants on the glass: If there are stubborn or hard contaminants on the glass, remove them manually. These contaminants can easily damage the wiper blades, leading to poor wiping performance and potential damage to the wiper motor. 3. Lift the wiper blades by holding the spine when necessary: When lifting the wiper blades for car washing or routine cleaning, hold the spine of the wiper blade and gently return it to its position. 4. In winter, use an ice scraper to remove ice from the windshield before using the wipers: During winter use, first remove ice from the windshield with an ice scraper to avoid putting extra strain on the wipers.
I've found that wiper noises usually have several common causes. Firstly, aging wiper blades are the most prevalent issue - hardened rubber material creates squeaking sounds when rubbing against glass over time. Secondly, unclean windshields with accumulated dust, oil film, or insect residue produce a zipping sound during operation. I've seen many vehicles develop frequent noises when not cleaned before rainy seasons. Additionally, improper wiper arm positioning (sometimes knocked askew when parked) causes clattering during uneven wiping. Mechanical components like loose linkages or insufficient lubrication also generate noises, especially exacerbated in dry weather. For maintenance, I recommend checking wiper blade wear every six months and timely replacement; regularly using glass cleaner on windshields; and avoiding dry-wiping to prevent damage. These practices minimize issues for safer driving.
