Why are there water droplets at the car's air conditioning vents?

[ErinAnn]

The reasons for water droplets at the car's air conditioning vents are as follows: Air conditioning set too low: When the air conditioning is set too low, moisture in the air can condense on the outside of the vents, creating a white mist effect. The moisture can also condense on the plastic casing of the evaporator or the surface of the plastic ducts delivering cold air, leading to dripping. Evaporator: This situation is more likely to occur in vehicles with poor insulation on the plastic casing of the evaporator or the plastic ducts delivering cold air. Poor vehicle sealing: High-humidity outside air continuously leaks into the car interior. Another typical symptom of excessively high humidity inside the car is the condensation of water droplets around the vents.
