What Causes the Squeaking Noise When Wipers Move on the Windshield?
3 Answers
The squeaking noise when wipers move on the windshield is caused by: 1. Wiper-related issues: Aging or hardening of the wiper blades, which are rubber products, can lead to such noise over time; 2. Linkage mechanism problems: Continuous or improper use may cause deformation or rusting of the linkage, resulting in noise; 3. External factors: The presence of foreign objects between the wiper and the windshield, or dry wiping (operating the wipers without water on the windshield) can also cause noise. Wipers are blade-like structures installed in front of the windshield, composed of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. Their primary function is to clear rain, snow, and dust from the windshield that may obstruct visibility.
Hey, I've been having this annoying squeaking sound from my wipers lately when driving. It's probably because the wiper rubber has aged or hardened, especially noticeable in cold weather. There might be oil film or dust on the windshield, causing friction noise when the wipers sweep across. Last time I went to the car wash, the mechanic said worn rubber can easily crack and suggested replacing the wiper blades every six months for peace of mind and safety. If left untreated, the noise will only get worse, not to mention reduced visibility in rain, which is risky on highways. Try cleaning with windshield washer fluid first; if it still squeaks, replace them. Remember to clean the windshield regularly during car washes to prevent dirt buildup for a safer drive.
As an experienced driver, the reasons for squeaky wipers are simple: first, the wiper blades are aged and cracked, with hardened rubber that squeaks when scraping the glass; second, there may be oil stains or small stones on the glass surface, hindering the wiper's movement. Solution: First, spray some cleaning fluid to rinse the glass. If the problem persists, check if the rubber strips need replacing. Loose brackets are also common—shake the wiper arm by hand to check. Replacing the blades is inexpensive and can be done in just a few minutes. Remember to perform regular maintenance, such as inspecting and replacing blades before the rainy season, to avoid noise affecting visibility and driving safety. Ineffective wipers reduce visibility and increase the risk of accidents—never overlook this issue.
