Where Does the Car Air Conditioner Drain Water From?

[Tabitha]

Car air conditioner drain outlets are typically located at the bottom of the evaporator box, connected to the chassis via a hose. If the air conditioner drain outlet becomes blocked, water can seep into the passenger footwell through the connection, soaking items like floor mats. The function of the air conditioner drain outlet is to expel water condensed during the heat exchange process when the air conditioner is in use. The evaporator box continuously absorbs heat and condenses moisture from the surrounding air, which is then drained out. The condensation water from the car air conditioner is produced during the cooling process, and the condensation water pipe is located beneath the chassis. Other drain outlets on a car include: 1. Engine compartment drain hole; 2. Sunroof drain hole; 3. Fuel tank cap drain hole; 4. Door drain hole; 5. Trunk drain hole.
