What are the causes of abnormal noise from the Lavida's air vents?
2 Answers
The causes of abnormal noise from the Lavida's air vents are: whether there are foreign objects in the air duct; or a malfunction of the internal and external circulation damper motor. Placement and replacement of the air conditioning: There should be no items near the air intake of the air conditioning to prevent blockage of the intake, which could hinder the air circulation of the air conditioning system. The air purifier of the air conditioning should be replaced regularly. The deodorizing filter should be replaced approximately every 3 months or after the car has run about 5,000 kilometers. Temperature of the air conditioning coolant: The air conditioning system should be used when the engine coolant temperature is normal. If the engine is under heavy load and causes the coolant temperature to rise excessively, the air conditioning should be stopped until the coolant temperature returns to normal before being used again.
When driving my Lavida, I encountered annoying noises from the air vents. The most common issue is dust or small leaves accumulating on the fan, causing squeaking sounds when the AC is turned on. It's like when a car isn't properly maintained over time, and the fan blades rotate while rubbing against the dirt, naturally producing noise. Sometimes, foreign objects get sucked into the vents and get stuck—like that time during a long highway drive when roadside paper scraps blew in, making the fan spin unevenly. Aging bearings are another reason; lack of lubrication during rotation can cause creaking sounds. I've tried using a vacuum to clean the vents myself, but the effect doesn't last long. It's best to have it checked at a professional shop. Regularly replacing the AC filter can prevent dust buildup. The Lavida's vent design tends to trap dirt easily, so don't wait for the noise to start before paying attention to maintenance.
