Why is the car's air conditioner leaking water into the car?

[DeCatherine]

The reasons for the car's air conditioner leaking water into the car are as follows: Air conditioner drip pipe leaking: When the car's air conditioner is turned on, the drip pipe under the car drips water onto the ground, which is a normal phenomenon. Drain pipe blockage: The drain pipe of the evaporator housing is blocked. Drain pipe loosening: The evaporator housing is broken or the drain pipe is loose. Poor insulation of cold air ducts: Poor insulation of the evaporator housing or the ducts delivering cold air. Inability to discharge humidity inside the car: The air is too cold, causing water in the air to condense at the outlet. Continuously using the outside air circulation function allows high-humidity outside air to constantly enter the car, and the humidity inside the car cannot be discharged outside, resulting in leakage.
