How to Deal with Odor in Odyssey's Air Conditioning?
2 Answers
Methods to address the odor in Odyssey's air conditioning are as follows: 1. Use an automotive air conditioning duct cleaner: The cleaning method is quite simple. Park the car in an area with good air quality, turn on the external circulation, set the air conditioning to the natural ventilation mode, then spray the cleaner evenly into the air vents. After a few minutes, open the windows and turn on the air conditioning to thoroughly ventilate the car. 2. Utilize sunlight and UV rays to remove odor: For mild air conditioning odors, you can drive the car into the sunlight on a sunny day, set the air conditioning system to the warm air mode, and turn the fan to the maximum speed. With all doors and windows open, let the car sit for about ten minutes. This not only uses UV rays to disinfect the interior but also allows the hot air to thoroughly circulate and clear out any dirty air in the ducts. Tips to prevent moldy odors in the air conditioning: In the summer, before turning off the engine, turn off the air conditioning compressor in advance and switch the mode to external circulation. This allows hot air to dry any moisture in the air conditioning ducts, preventing bacteria growth and subsequent odors due to dampness.
I just dealt with a lot of Honda Odyssey air conditioning odor issues at the auto repair shop. The main cause was the damp and moldy evaporator in the AC system. First, check if the cabin air filter is dirty. The Odyssey's filter is located behind the glove box, and it's super easy to remove and replace it yourself—just choose a high-quality OEM filter. If the odor persists, a professional cleaning is needed: take the car to the shop, where they use high-pressure disinfectant spray into the air ducts to kill mold and bacteria. I recommend turning off the A/C cooling a few minutes before parking and only running the external circulation fan to dry it out, which can prevent the problem from recurring. You can also use AC cleaning foam for DIY spray cleaning—just follow the instructions, but avoid cheap, low-quality products as they can damage components and cause more trouble.
