What Causes Loud Noise from Car Wiper Blades?
2 Answers
Reasons for loud noise from car wiper blades: 1. Presence of impurities like sand or gravel between the wiper blade rubber and the windshield; 2. Incorrect size of the wiper blade rubber; 3. Aging of the wiper blade rubber, causing it to harden; 4. Improper installation of the wiper blade support frame; 5. Lack of lubrication on the wiper blade rubber, making it too dry. Regular inspection of the wiper blades is essential to check for deformation or wear. Timely replacement when issues arise can reduce damage to the windshield and ensure normal use by the driver. It is important to note that when cleaning the car windshield, water should not be used as a substitute for windshield washer fluid. Windshield washer fluid not only cleans the glass but also provides lubrication, which can extend the lifespan of the wiper blades.
I've been driving for decades and often encounter the issue of noisy windshield wipers. This is usually caused by the wiper blades aging and becoming stiff, causing them to squeak when rubbing against the glass. Another major reason is unclean glass, where dust or bird droppings accumulate, making the wipers screech when in use. If the wiper arm tension is too tight or unbalanced, it increases friction and noise. Sometimes, in dry weather, the glass becomes too dry, making the wiper movement less smooth and increasing noise. It's recommended to first spray some windshield wiper fluid to moisten the glass, replace the blades every six months, and maintain good cleaning habits for a quieter and more comfortable driving experience.
