What causes the abnormal noise in the Wuling Hongguang Mini's wiper?

The abnormal noise in the Wuling Hongguang Mini's wiper may be caused by foreign objects trapped between the wiper blade and the windshield. In this case, it is necessary to check and clean the wiper blade or any debris underneath it. Below are the possible reasons: Worn-out rubber blade due to prolonged use: Impurities on the windshield, the quality of the wiper blade, or aging, deformation, and hardening of the rubber blade (wiper blade) over time; linkage mechanism. Deformation of this mechanism or issues with the motor, intermittent relay, etc., may cause abnormal noise, especially as usage time increases. Motor-related issues: Poor motor performance or external circuit voltage issues can lead to abnormal rotation or noise, such as insufficient working voltage. Additionally, problems with the relay control section can also cause abnormal operation or noise.
I previously experienced squeaky wipers on my Hongguang MINI as well, and later figured out there are mainly three common issues. Aging rubber blades are the most frequent culprit, especially after parking outdoors under direct sunlight – hardened rubber scraping the windshield sounds like chalk on a blackboard. Oil film buildup on the glass can also cause this, particularly after driving through sprinkler truck sections during rain, where wipers skip and produce strange noises; vigorously cleaning the windshield with dish soap solved it. Also, never cheap out on off-brand wipers – once I installed aftermarket blades that immediately "danced" across the glass, later discovering the bracket angle was misaligned. Regularly wipe blade rubber with a damp cloth to remove grit, and replace blades before rainy season – these steps basically prevent such headaches.
