What Does It Mean If My Car Is Leaking Water?
It is normal for water to leak from the air conditioner drain located under the car on the front passenger side. However, water leaking into a car is a sign that the air conditioner or moon-roof drains are clogged.
An automotive air conditioner removes water from the air inside the car, condenses it and releases it into the drain. The drain is controlled by a one-way burp valve, which can get clogged if the water coming from the air conditioner contains dirt. A clogged burp valve causes water to back up and leak into the cabin. The same happens if there is a clog close to the air intake of the air conditioner or in any of the other drains in the body and doors of the car, such as the moon-roof drain.
