What Causes the Bad Smell in the Vision X3 Air Conditioning?
3 Answers
Vision X3 air conditioning bad smell may be caused by the long-term failure to replace the car's air conditioning filter, leading to bacterial growth and odor. The following is an introduction to car air conditioning: 1. Car air conditioning is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car compartment to the optimal state, providing passengers with a comfortable riding environment and reducing travel fatigue; it also creates good working conditions for the driver and plays an important role in ensuring safe driving as a ventilation device. 2. The car air conditioning refrigeration system consists of a compressor, condenser, liquid storage dryer, expansion valve, evaporator, and blower, among others. These components are connected into a sealed system using copper pipes (or aluminum pipes) and high-pressure rubber hoses.
I often encounter the issue of a foul smell in the Geely Vision X3's air conditioning system, mainly due to mold growth on the evaporator. When the AC is cooling, it condenses moisture, which accumulates on the evaporator and fosters mold, producing a smell similar to wet socks. Another issue is the air filter not being replaced for too long, as dust and debris build up and block airflow, causing odors. Additionally, if the drain pipe is clogged, water can't drain properly and stagnates in the system, breeding bacteria. This usually happens in humid weather or after infrequent AC use. I remember one time when I didn’t address it promptly, the smell grew stronger while driving, affecting my mood. To prevent this, it's recommended to regularly clean the AC internals during maintenance, such as using professional cleaning sprays on the evaporator or drying it with high airflow. Replacing the air filter every six months can also reduce odor sources. Neglecting this not only leads to unpleasant smells but may also cause allergy issues. Getting a thorough cleaning at a repair shop in time will save a lot of hassle.
The foul smell in the Geely Vision X3's air conditioning usually stems from mold on the evaporator or a dirty filter. When the AC cools, the evaporator gets damp, creating a breeding ground for bacteria that causes odors. A clogged filter also worsens the problem by trapping stale air. Drainage issues are another culprit—blocked tubes lead to stagnant water and bad smells. I recommend starting with simple fixes: check the filter and replace it if dirty. Then use cleaning foam on the evaporator or run the heater at high fan speed to dry it out. These steps can be done at home. If the issue persists, visit a 4S shop for a full system check. Regular maintenance is key—cleaning the AC quarterly prevents problems. Ignoring the smell degrades cabin air quality, harming health and driving comfort. Address it promptly to avoid bigger headaches later.
