Why Do Car Windshield Wipers Make Noise?
2 Answers
There are several reasons why car windshield wipers make noise: 1. Friction in the wiper linkage bushing; 2. Malfunction of the wiper motor; 3. Aging and hardening due to prolonged use; 4. Foreign objects trapped between the wiper blade and the windshield. Solutions for noisy windshield wipers include: 1. Directly replacing the wiper blades with new ones; 2. Inspecting and cleaning any foreign objects under the wiper blades or wipers; 3. Checking the wiper arm or wiper linkage bushing; 4. Taking the car to a professional repair shop for a detailed inspection. Precautions for using windshield wipers include: 1. Promptly replacing or cleaning the wiper blades when they are severely worn or dirty; 2. Wetting the windshield with water before checking the wiper operation; 3. Ensuring the wiper blades return to the lower side of the windshield and stop after turning off the wiper switch.
The noise from car wipers is really annoying. After driving for so many years, I've encountered this issue multiple times. Usually, it's because the wiper blades have aged and hardened, causing too much friction when wiping the glass; or there's oil film or tree sap on the windshield that wasn't cleaned properly. Once on a rainy day on the highway, the wipers suddenly started squeaking—after inspection, it turned out the wiper arm pressure was uneven, pressing too tightly and causing the noise. Don't underestimate this issue; blurred vision in the rain poses serious safety risks. It's recommended to replace wiper blades every six months, opting for silicone material for better durability. Regularly use glass cleaner for thorough washing to maintain lubrication. If the noise persists, don’t delay—visit a repair shop promptly to avoid escalating hazards. Developing good daily habits is the safest approach.
