What causes the wiper noise in Wuling Hongguang Mini?
3 Answers
Wuling Hongguang Mini wiper noise is caused by aging wiper blades. Below is a detailed introduction to the Wuling Hongguang Mini: Positioning: The Wuling Hongguang Mini is a micro-sized pure electric vehicle with the battery located under the chassis. The vehicle can be charged using a standard household 220V three-pin power outlet with a charging power of less than 2kW, and charging times are approximately 6 hours and 9 hours. Configuration: The driver and front passenger seats can be adjusted forward and backward, as well as the backrest angle. The rear seats support a 50:50 split-folding ratio. It comes with features including brake force distribution, ABS anti-lock braking, tire pressure monitoring, child seat anchors, seatbelt reminder, parking sensors, hill-start assist, aluminum alloy wheels, a full LCD instrument panel, power windows, and remote door locks.
When driving my Wuling Hongguang Mini, I also encountered wiper noise issues and found that the common cause is aging and hardening of the wiper rubber blades. Especially after summer sun exposure, the rubber can deform, making a squeaky sound like a mouse gnawing on wood. Additionally, sand particles or tree sap residue on the windshield can cause the wipers to slip and jump like they're dancing, producing that unsettling tapping noise. Another small detail is that the wiper arm spring may age, leading to insufficient pressure—like a weak hand unable to press the wiper blade firmly. Once after rain, I touched the edge of the rubber blade and noticed tiny cracks, which made me realize the issue. I recommend replacing the rubber blades every six months and spraying water to soften them before wiping the windshield—unlike my buddy who wipes dry, creating a sound that could make your ears callous.
A couple of days ago, my car's wipers suddenly started making a croaking sound like a frog. Upon inspection, I found that the wiper linkage was rusted and lacked lubrication. Rainwater seeping into the linkage area can easily cause rust, making a screeching noise similar to stepping on a rusty bicycle pedal. While at it, check if the mounting screws are loose—if the motor base is displaced, it can shake like a cramped leg. Another often overlooked issue is the oily film on the windshield. Rub the glass with your fingertip; if it feels greasy, that’s the culprit. I use a clay bar to clean the glass every season, as meticulously as cleaning a phone screen before applying a screen protector. Remember not to let the wipers run dry, as it can damage the mechanism, much like letting a treadmill run without anyone on it wears out the belt.
