Where is the car air conditioner drainage located?

Car air conditioner drainage outlets are all designed at the lowest point below the condenser in the cabin. The specific location varies by vehicle model, but you can find the drainage outlet by locating the condenser in the cabin. More information about car air conditioner drainage outlets is as follows: 1. The function of the air conditioner drainage outlet is to discharge water condensed during the heat exchange process when the evaporator absorbs moisture from the surrounding air while the air conditioner is in use. 2. After the air conditioner has been running for a while, a puddle of water may appear under the car, which is water discharged from the car air conditioner drainage outlet.
With over ten years of experience in car repair, I often get asked by car owners about the location of the air conditioning drain. It's typically located underneath the car's chassis, specifically where the water drains from the evaporator. The evaporator is situated behind the dashboard. When the air conditioning is on, the heat exchange process causes moisture in the air to condense into water droplets. Once enough water accumulates, it drains out of the car through a small tube. If you look under the car, you'll usually find it near the center, behind the engine. Sometimes, you might notice water dripping onto the ground when the car is idling—this is completely normal and nothing to worry about; it actually indicates that the air conditioning is working properly. However, if the drain gets clogged, water can leak into the car, leading to a musty smell or wet floor mats. In such cases, check if the tube is blocked by mud or debris. If necessary, use an air gun to clear it or take the car to a shop for maintenance. Keeping the drain clean helps prevent odors and rust.
When I first started learning to drive, I often wondered why there was always water dripping under the car. After checking, I found out it was the air conditioning drainage. It's hidden in the middle of the car chassis, slightly towards the front wheels, and is a thin tube connected to the air conditioning evaporator, draining the condensed water droplets outside. Usually, when parked in a garage or on the roadside, you can see small water stains on the ground after using the air conditioning, especially when using the cold air in summer. Once, I noticed a damp smell in my car and found out the tube was blocked by leaves. After cleaning it promptly, the issue was resolved. I recommend checking the drainage hole regularly to ensure it's clear, so you don't end up like me, unaware, and avoid water flowing back into the cabin causing mold. This phenomenon is quite common and indicates normal air conditioning operation, so there's no need to worry.
