Here are the possible reasons why a car wiper keeps making noise: 1. The first scenario is noise caused by friction between the wiper and the windshield, which may be due to the wiper being aged or having dust and debris. In this case, gently sand the wiper with fine sandpaper and wipe it clean with a cloth. For severely dry wipers, applying some lubricating oil can help. 2. The second scenario is improper adjustment of the wiper frame, where the wiper is too tight, causing excessive friction. Adjust the wiper frame to make it slightly looser. 3. The third scenario is an issue with the assembly of the wiper frame, leading to excessive effective travel of the wiper arm, which causes noise when it contacts the windshield frame during its return stroke. Adjust the wiper arm to reduce the effective travel. 4. The fourth scenario is rust or aging of the wiper frame itself, which produces noise. Solutions include cleaning and removing rust, applying anti-rust paint, or replacing the wiper entirely if it is too severely aged to be repaired.

There are quite a few possible reasons for noisy wipers. Experienced drivers often point to worn or aged wiper blades as the most common cause, where hardened or deformed rubber increases friction noise—annoying squeaks against the windshield. Another culprit is dirt or dust on the glass surface hindering smooth movement, especially common in dusty urban driving. Misaligned wiper arm angles or loose springs can also create uneven pressure, leading to irritating squeals. DIY checks are simple: first, clean the glass and blades with a damp cloth to see if the noise stops. If not, remove the blades to inspect for cracks; replacements usually cost just a few bucks. Park in the shade to protect rubber from sun damage, and avoid dry-wiping to reduce wear. While minor, the noise can distract from safe driving—bi-annual checks prevent bigger issues.

As a car enthusiast who loves tinkering with vehicles, I've analyzed that wiper noise usually stems from mechanical defects. For instance, dry scraping friction caused by aged and cracked rubber on wiper blades, or jumping sounds due to improper spring adjustment of the wiper arm resulting in uneven pressure. Residual grease or tree sap on the windshield can also increase resistance and cause abnormal noises. More deeply, it might be insufficient lubrication of the wiper motor causing buzzing vibrations, especially noticeable during rainy days when the load is heavier. Quick tip: First, thoroughly clean the glass with a glass cleaner and test the wiper's performance; if it improves, it indicates a dirt issue. If ineffective, check if the wiper blade is flat and undamaged—replacing it yourself takes just minutes. Don't overlook this, as wiper failure could impair visibility and lead to accidents during heavy rain.

I personally find that most of the noise from windshield wipers while driving is due to either aging wiper blades or a dirty windshield. During daily commutes, dust accumulation can cause the blades to squeak annoyingly when wiping. Dry weather can also exacerbate friction and produce noise. Simple solution: when washing the car, use dedicated wiper fluid to clean the windshield thoroughly and check if the wiper blades are deformed or cracked. If there's an issue, just buy a new blade and replace it yourself—it saves money and hassle.
