How to Solve the Squeaking Noise When New Wiper Blades Scratch the Windshield?
3 Answers
When the wiper system produces "abnormal noise" during operation, it is recommended to first check the source of the noise, which could be the motor, the linkage mechanism, or the friction between the wiper blade and the windshield. In such cases, directly replacing the wiper blade is a viable solution. Below are detailed explanations and solutions: 1. Wiper Arm and Wiper Blade: Impurities on the windshield, the quality of the wiper blade, or prolonged use leading to aging, deformation, or hardening of the rubber strip can cause improper contact with the windshield or turn the "wiping" action into a hard "scraping" motion, resulting in abnormal noise. If this occurs, the wiper blade can be directly replaced. Additionally, adding some specialized cleaning fluid to the washer reservoir can enhance lubrication and eliminate the noise. 2. Linkage Mechanism: Deformation of this mechanism, or influences from the motor and interval relay, can lead to abnormal noise. Over time, structural deformation, jamming, or rusting can also cause operational abnormalities, which may result in "abnormal noise." 3. Motor Part: Poor motor performance or issues with external circuit voltage can cause irregular rotation or noise. For instance, insufficient working voltage can lead to such problems. Additionally, control issues with the relay can also cause abnormal motor performance or noise.
I just replaced my new wiper blades, but they made annoying squeaking noises when wiping the glass. Later, I figured out the solution myself. The most common cause is oil film or dust residue on the glass. Don’t rush to blame the wiper blades—first, clean the glass surface with a damp cloth, especially the corners that are rarely washed. The wiper rubber strips also need cleaning; gently wipe them with a towel dipped in soapy water to remove dirt and lubricate them in one go. If installed in the wrong direction, they’ll squeak too—don’t ignore the arrow indicator, and make sure it aligns with the edge of the windshield. Dry wiping is a big no-no; always spray water to wet the glass before turning on the wipers. I stick to this monthly maintenance routine, and now the wipers glide smoothly and quietly, extending their lifespan and saving money. For stubborn grease, a quick spray of automotive glass cleaner eliminates the noise in seconds. Don’t skip these simple steps—they ensure clear and safe driving visibility.
The squeaking noise after replacing new wipers is mostly due to overlooked minor details. Based on my experience handling similar issues: First, check if the wiper rubber blade is stuck with foreign objects or deformed, and gently adjust its balance by hand. Cleaning the glass surface is crucial—stubborn stains can be removed with professional cleaners, but ordinary alcohol wipes can eliminate oil stains. When installing wipers, ensure the rubber blade fits snugly against the glass to avoid vibration noises caused by air gaps. If the arm pressure is uneven, slightly adjust the fixing screws or apply lubricant spray to the joints. Low-quality wiper blades age quickly, so choosing reputable brands is more reliable. Inspect the rubber blade for wear every quarter and replace it promptly to avoid safety hazards. These minor fixes keep your beloved car in top condition, ensuring smooth driving in rainy weather.
