What Causes Abnormal Noise in Car Windshield Wipers?
2 Answers
Car windshield wipers produce abnormal noise due to the following reasons: 1. Aging and hardening after prolonged use; 2. Foreign objects trapped between the wiper blade and the windshield; 3. Friction in the wiper linkage bushing; 4. Malfunction of the wiper motor. Solutions for abnormal noise in car windshield wipers include: 1. Directly replacing the wiper blade with a new one; 2. Inspecting and cleaning any foreign objects under the wiper blade or wiper; 3. Checking the wiper arm or wiper linkage bushing; 4. Conducting a detailed inspection at a professional repair shop. Precautions for using car windshield wipers are: 1. Replace or clean the wiper blade promptly when severe wear or dirt is noticed; 2. Wet the windshield with water before checking the wiper's operation; 3. After turning off the wiper switch, the wiper blade should return to the lower side of the windshield and stop.
My car's wipers were squeaking a while back, took me several tries to figure it out. The issue is most likely due to aging wiper blades or debris stuck in them. I carefully cleaned the blade gaps with a toothbrush, and the noise disappeared once those tiny gravel bits were gone. If they've been used for over two years, it's best to just replace the blades – go for silicone ones as they last longer. Another trick is to thoroughly clean the windshield with dish soap; leftover oil film can cause the wipers to chatter. Remember to wipe the blade edges with a damp cloth during each car wash – sudden noises during rain are really annoying.
