What causes the wiper noise in BMW X3?
1 Answers
Analysis of reasons for wiper noise on windshield: 1. Wiper arm and wiper blade: Common causes include glass impurities, poor quality of wiper blades, or aging, deformation, and hardening of the rubber strip (wiper blade) due to prolonged use. 2. Linkage mechanism: Deformation of this mechanism or influences from components like the motor and intermittent relay may cause abnormal noises. Additionally, structural deformation over time can lead to operational abnormalities, all of which may result in "abnormal noise". 3. Motor part: Poor motor operation or external circuit voltage issues can cause abnormal rotation or noise. For example, when the voltage is below the working voltage, or due to relay control issues, the motor may operate abnormally or produce noise. Adjustment method: Mainly adjust the angle of the wiper linkage arm.
