What Causes the Squeaking Noise When New Wiper Blades Are Used?
2 Answers
The squeaking noise when new wiper blades are used can be attributed to issues with the wiper blades themselves, foreign objects between the wiper blades and the windshield, or problems with the linkage mechanism. Issues with the wiper blades themselves: Wiper blades are made of rubber and can harden or deteriorate over time, especially in winter. If they no longer clean effectively, the simplest and most effective solution is to replace them with new ones. Foreign objects between the wiper blades and the windshield: When the wipers are turned on, a sharp friction noise may occur between the blades and the windshield. The owner can inspect and clean any debris under the wiper blades to ensure they remain clean. Linkage mechanism: Deformation of this mechanism or issues with the motor and interval relay (such as operating too fast, too slow, or continuously) can cause abnormal noises. Additionally, prolonged use may lead to deformation, stiffness, rust, or other operational anomalies in the mechanism itself. If the wiper blades are newly replaced, it is advisable to check for dirt or oil residues on the windshield and clean it with a cleaning solution or try another new set of blades. If the noise persists, adjust the angle of the wiper arm using tools like pliers. However, it is recommended to visit a repair shop for professional adjustment with specialized tools.
I've been driving for many years, and it's quite common for new wipers to make strange noises when wiping the windshield. This could be due to improper installation—the wiper isn't securely fixed and jumps while wiping, causing noise. Alternatively, there might be an oil film or dirt on the glass surface, such as residue left after washing the car, which increases friction and produces noise. Another possibility is that the wiper blade itself is of poor quality, with rubber that's too hard or a design flaw, especially common with cheaper products. I recommend first cleaning the windshield with some glass cleaner, checking if the wiper arm screws are loose, and gently pressing by hand to test the fit. If the noise persists, try replacing the wiper blade with one from a reputable brand. For prevention, avoid leaving the car exposed to the sun for too long in summer to prevent the wiper rubber from hardening and aging. In short, don't underestimate this issue—noises can affect visibility in rainy or foggy weather, so it's safer to address it promptly.
