Why is the air conditioning water leaking into the car in the Ono?
2 Answers
The reasons for the air conditioning water leaking into the car in the Ono are as follows: Poor drain pipe: Long-term use of the drain pipe leads to aging, loosening, or bending, resulting in a wavy shape that causes poor drainage and partial blockage, allowing water to flow into the car. Clogged drain outlet: The drain outlet is blocked by dirt, preventing the condensation water from draining, which slowly causes the water level to backflow and eventually flow into the car. Improper installation of the unit: Excessive tilting of the unit or excessively high pipe cross-direction prevents water from circulating, leading to water accumulation that over time flows into the car. Condensation on the pipes: The insulation material on the pipes is too poor or too thin, causing condensation when the refrigerant passes through the pipes, which then melts and flows into the car.
I've encountered this issue a few times during my years of driving. Water leakage in the car is mostly caused by the air conditioning condensate not draining properly. In vehicles like the Ouno, the air conditioning system generates a lot of moisture when cooling, which should normally drain out through a dedicated tube under the chassis. However, if the drain tube gets clogged with dust, leaves, or small insects, the water has nowhere to go and ends up flowing back into the cabin, often emerging from the air vents or under the floor mats. When I check it myself, I lift the carpet to see where the moisture is coming from and try to locate the drain outlet in the engine compartment below the windshield, using a thin wire to clear any blockages. If not addressed promptly, the car can develop mold and unpleasant odors, or even corrode metal parts, increasing repair costs. I recommend regular maintenance of the air conditioning system, especially when parked under trees or in dusty environments, to avoid prolonged blockages. If the problem becomes severe, it's best to take it to a professional shop for repairs, to prevent minor issues from turning into major headaches.
