Why is the windshield wiper making loud noises?
2 Answers
The reasons for loud windshield wiper noises: 1. The windshield is dirty or dry, causing the wiper blade to scrape harshly and produce noise. It is recommended to clean the glass with detergent or a degreaser. 2. The rubber blade of the wiper has aged due to exposure to wind and sun. Since the windshield is curved, the hardened rubber blade does not glide smoothly, resulting in noise. It is advised to replace the wiper blades. 3. The spring inside the wiper arm has poor elasticity or is too stiff, exerting excessive pressure on the wiper blade against the glass, leading to noise. Simply install a new pair of springs. 4. The gear lubricant in the wiper motor has dried up. It is recommended to disassemble and reapply grease.
I've been driving for over twenty years and have encountered the issue of squeaky wipers several times. It's usually because the wiper blades have aged, causing the rubber to harden or develop cracks, which makes them squeak when wiping the glass. Sometimes, oil stains, dust, or even insect remains on the windshield can also cause friction noise if not cleaned properly. I remember it being particularly severe last winter because the cold made the rubber even more brittle, resulting in loud squeaking. It's advisable to regularly inspect the wiper blades and replace them every six months or so, while also keeping the windshield clean by wiping it with a damp cloth. If the noise persists after replacement, it might be due to loose or deformed wiper arms, which need immediate attention—otherwise, it can be dangerous in rainy weather when visibility is poor. It's a simple and low-cost DIY fix you can do at home.
