Why is there noise when the BMW wiper is working?
2 Answers
BMW wiper makes abnormal noise should first check the source of the noise. Detailed reasons and specific solutions for abnormal noise when the BMW wiper is working are as follows: 1. Wiper arm and wiper blade: Impurities on the glass, prolonged use of the wiper blade, etc., cause aging, deformation, hardening of the rubber strip. In this case, you can directly replace the wiper blade, and add some special detergent to the car's water spray bottle to increase lubrication and eliminate abnormal noise. 2. Linkage mechanism: Deformation of the linkage mechanism or the influence of the motor, gap relay, etc., may cause abnormal noise. Also, due to prolonged use, its own structure may deform, jam, or rust, causing abnormal operation. 3. Motor part: Poor working condition of the motor or external circuit voltage may cause abnormal rotation or noise, such as when the voltage is insufficient. In addition, there are reasons related to the relay control part, which may also cause abnormal working conditions or noise.
Having driven for decades, when encountering wiper noise, the first thing that comes to mind is aging or deformation of the wiper blades. Over time, rubber materials harden, increasing friction against the glass, which leads to squeaking. Additionally, there may be oil or dust buildup on the windshield, especially for city drivers who often park under trees, making them prone to contamination. Loose wiper arms are also a common issue; improper installation can cause uneven pressure on the blades, resulting in erratic noise. These might seem like minor issues, but with blurred vision during rain, driving becomes extremely dangerous. I recommend regularly checking the wiper blades and replacing them every six months—it's not costly. Timely cleaning of the windshield can also help alleviate the problem.
