Why is there water leakage from the car air conditioner?
2 Answers
Water leakage from the car air conditioner is an abnormal phenomenon, which may be caused by poor drainage or even blockage of the drain pipe. The following is a detailed analysis of the specific reasons: 1. Poor drainage: Long-term use of the drain pipe can cause aging, loosening, or bending into a wave shape, leading to poor drainage and local blockage. Solution: Contact the manufacturer or a qualified air conditioner repairer to replace the drain pipe. Users can also purchase an ordinary PVC thin pipe as a replacement, but the outdoor unit part of the construction is somewhat difficult, and it is also necessary to remove the protective tape, which is quite troublesome. 2. Blocked drain pipe: The drain pipe leading outside is artificially blocked or the drain outlet is blocked by debris, preventing the condensation water from draining. Solution: If the architectural design includes a drain pipe, it is important to check whether the drain pipe is clear and whether the connection between the drain pipe and the air conditioner pipe is properly made.
Last year, my car's air conditioning started leaking, and the floor mats were always wet. After checking, I found out it was due to a clogged drain pipe. When the AC runs, moisture from the warm air condenses on the evaporator and is supposed to drain out through the pipe under the car. However, if dust or leaves block it, the water flows back into the car. I tried cleaning it myself: opened the hood, located the drain outlet, used a small brush to remove the buildup, and then flushed it with a hose. Now, the leaking issue is mostly resolved. I recommend not ignoring this problem, as the moisture can cause the carpet to mold, leading to unpleasant odors and bacterial growth inside the car, which affects health. To prevent this, turn off the AC a few minutes before parking to let the system dry out and replace the filter regularly to avoid clogs.
