Why Are There Water Droplets at the Car Air Conditioning Vents?

[LuciaLynn]

Here are the reasons for water droplets at the car air conditioning vents: Air Conditioning Too Cold: Moisture in the air condenses on the outside of the vents, creating a phenomenon resembling white smoke. Moisture can also condense on the plastic casing of the evaporator or the outer surface of the plastic ducts delivering cold air, leading to dripping. Models with poor insulation on the evaporator's plastic casing or the plastic ducts for cold air delivery are more prone to this issue. High Humidity: Excessive humidity inside the car can also easily cause the above problem. Blocked Drainage Pipe: If the drainage pipe of the evaporator's plastic casing is blocked, water may overflow when the level gets too high, causing dripping inside the car. Damage: Cracks in the evaporator's plastic casing or loose drainage pipes can also result in water dripping inside the car. Leakage: A cracked small heater core inside the dashboard can cause engine coolant to leak.
