How to Deal with Clogged Car Air Conditioning Pipes?
2 Answers
Turn off the power, use a Phillips screwdriver to open the front panel and partition, exposing the condenser and drainage tray. Fill a mineral water bottle with water and flush the drainage pipe along the tray, repeating several times to see if it can be unclogged. If not, use a thin wire to slowly unclog it, remove the blockage, and then rinse with water until the drainage is smooth. Reinstall the partition and panel in the reverse order of removal. Here is additional information: Air conditioning drainage outlet: The air conditioning drainage hole is located under the chassis, and its exact position varies by car model. The car air conditioning produces condensed water during the cooling process, and the condensed water pipe is located under the chassis. During the rainy season, passing through mud and stagnant water can also lead to clogging of the drainage hole, with consequences similar to those of a clogged engine compartment drainage hole—water may flow back into the car, causing water accumulation on the floor. Cleaning method: Crawl under the chassis and use a thin wire to handle it; the unclogging process is relatively simple.
Last time my AC vents weren't blowing properly, I discovered clogged ducts. Dust and grime had accumulated in the air ducts, preventing cool air from coming out and increasing fuel consumption. I first tried cleaning it myself: after turning off the AC and engine, I removed and cleaned or replaced the air filter, used a vacuum to suck out dust from the vents, with mixed results. The blockage might be due to years of dust buildup or mold growth, especially common during humid seasons. Ignoring it can lead to bad odors affecting the driving experience. If DIY doesn't work, take it to a repair shop for professional cleaning—they have flexible tube tools for deep flushing and drying. Now I regularly maintain and replace filters to prevent clogs. Checking the AC before summer is crucial; don't wait until problems escalate.
