Why is there abnormal noise when the wiper is wiping?

The reason for abnormal noise when the wiper is wiping could be due to aging or deformation of the wiper blade itself, or the presence of foreign objects between the wiper blade and the windshield. It is recommended that the owner first check for any foreign objects between the wiper blade and the windshield. Then, lift the wiper to the maintenance position and inspect the rubber part of the wiper blade for signs of hardening, burrs, gaps, cracks, or tears. If any of these issues are found, the wiper blade should be replaced. Another possible cause is the presence of an oil film on the windshield. If the wiper blade is ruled out as the cause, a water test can be performed on the windshield. If the water does not adhere to the glass or spreads quickly, it indicates the presence of an oil film, which can cause the wiper blade to vibrate or produce abnormal noise. In this case, the windshield should be cleaned using an oil and adhesive remover. Another possible issue is deformation of the wiper arm. Check if the lower plane of the wiper arm is in full contact. If there is an angle, it indicates deformation of the wiper arm. The angle of the wiper arm can be adjusted using a wrench. During adjustment, wrap the wiper arm with a thick towel to prevent the wrench from damaging the paint of the wiper arm.

It's quite common for wipers to make noise when operating, and I think it's mostly due to aging wiper blades. After driving for so many years, I've noticed that the rubber blades tend to harden and dry out after one or two years of use, causing squeaking sounds when wiping. Additionally, if there's oil film or tree sap residue on the windshield that isn't cleaned regularly, the wipers will produce friction noise upon contact. In cold winter weather, the rubber becomes even stiffer, resulting in louder noises. It's recommended to replace the wipers periodically, opting for high-quality brands, roughly every six months to a year. Don't forget to clean the windshield thoroughly during car washes, using degreasing products to help reduce noise. Alternatively, if the wiper arm spring is loose and causing uneven pressure, a simple adjustment or replacement of the arm can solve the problem. Never ignore unusual noises while driving, as they can be distracting and lead to accidents. Developing a habit of seasonal checks is essential for safety first.

My car's wipers keep making noise, especially when driving in the rain, which is really annoying. After consulting, I learned that when the wiper blades wear out, they become rough and make scraping sounds. The same happens when there's dirt on the windshield, like tree sap or bird droppings. I tried cleaning the glass myself, and using a neutral cleaner to wipe it can reduce the noise a bit. Replacing the wipers isn't difficult; you can buy them online for a few dozen bucks and change them yourself. In the summer heat, rubber tends to crack, so frequent replacement can prevent this. Usually, avoid letting the wipers scrape the glass dry; spray some water to wet it first before turning them on in the rain. If the wiper arm is bent or unbalanced, it can also cause jumping and noise, so check the installation position. Safety is very important; don't delay fixing the noise when it happens. A quieter drive makes for a better mood.

Many people complain about noisy wipers when repairing cars. Most of the time, it's caused by aging and cracked rubber strips creating friction sounds. Dirty glass or oily films can also easily cause noise. Solutions: Directly replace the wiper blades, ensuring the correct model is selected and installed tightly. Regularly clean the rubber strips with a wet cloth for maintenance to extend their lifespan. Tighten or replace loose wiper arms promptly. Motor issues are rare and require less attention. It's recommended that car owners inspect them every six months. Wiper blades are inexpensive, and replacing them early can save on repair costs. Regular maintenance prevents noise disturbances.
