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

[DeSavannah]

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.

The wiper noise on the Hongguang MINI is most likely caused by uneven pressure from the bracket. Once I tried to adjust the angle by removing the wiper arm myself, but when I put it back, the screw wasn't tightened properly, and the whole arm shook while wiping. If the wiper motor has unstable power supply, it can also act up, especially when the air conditioning is on and the car is charging—the motor hums rhythmically. Over time, the edges of the rubber blade can wear into a jagged shape, causing a 'clicking' sound when it reaches the corners of the glass. Keeping a bottle of oil film remover in the car is very useful; spraying it on the windshield every two weeks is much cheaper than getting it cleaned at the 4S shop. If you really can't fix it, take it to the shop and let the mechanic adjust the spring tension of the wiper arm—it's not an easy job to do yourself.

First, identify the type of wiper noise. A 'squeaking' sound usually indicates aging rubber blades—check for cracks by running your finger along them. If it's a 'buzzing' vibration, the issue is likely insufficient pressure due to rusted wiper arm springs. Last time I helped a neighbor fix their car, the pivot was clogged with tree sap, and WD-40 worked instantly. Opt for OEM rubber blades as they're softer; aftermarket ones tend to be stiff and prone to deformation. Avoid mixing washer fluid with tap water, as mineral deposits can clog the nozzles. If the wiring has been modified, check the fuse—a faulty relay can also cause wipers to jerk.

When repairing the car, I found that the squeaking noise of the Wuling Hongguang MINI's wipers is often due to the pivot issue. The wiper linkage of this car is exposed at the rear of the engine compartment, where poor heat dissipation in summer can easily cause rust, leading to squeaking when the grease dries up. If tree sap on the windshield isn't cleaned promptly, it hardens under the sun, making the wipers sound like they're scraping over pebbles. When doing it yourself, be careful not to overtighten the locking nut on the wiper arm, as it can put pressure on the pivot. Some owners install wiper dust covers, which can trap moisture and corrode the metal rod. If the wiper blades are too close to the windshield when parked, the rubber can stick in hot weather. When replacing the rubber blade, ensure the clips are fully pressed in; once, I only pressed them halfway, causing the blade to jump.

Unstable voltage can actually cause wiper noise, which I only noticed after installing a dash cam last time. Incorrect wiring led to insufficient power supply to the wiper motor, making it operate like it had Parkinson's. Especially when turning on the wipers with the AC running—if the headlights dim noticeably, check the battery voltage immediately. Even the factory 12V battery pack experiences wiper motor speed fluctuations in low temperatures. Once, my window was frozen, and I forced the wipers to operate—the gearbox made a sound like a tractor. It's recommended to inspect the relay contacts for burns, as poor contact can create current noise. Smart wipers are more sensitive than traditional mechanical systems—when the system misjudges windshield dryness, dry wiping damages the rubber blades even more.
