What Causes the Unusual Noise When BMW Wiper Blades Are Operating?
1 Answers
When BMW wiper blades produce unusual noises during operation, the first step is to identify the source of the sound. Detailed reasons and specific solutions for unusual noises from BMW wiper blades are as follows: 1. Wiper Arm and Blade: Impurities on the windshield, poor-quality wiper blades, or prolonged use causing the rubber strip (wiper blade) to age, deform, or harden can prevent proper contact with the windshield or turn the 'wiping' action into a hard 'scraping' motion, resulting in noise. In such cases, replacing the wiper blades directly is recommended. Additionally, adding some specialized cleaning fluid to the windshield washer reservoir can enhance lubrication and eliminate the noise. 2. Linkage Mechanism: Deformation of the linkage mechanism, or issues with the motor and interval relay (such as too fast, too slow, or continuous operation) can cause unusual noises. Over time, structural deformation, jamming, or rust in the mechanism can also lead to abnormal operation. 3. Motor Section: Poor motor performance or external circuit voltage issues can cause abnormal rotation or noise, such as when the voltage is insufficient for the operating voltage. Additionally, problems with the relay control section can result in abnormal operation or unusual noises.
