Occasionally car air conditioners will not only blow out cold air, but they will blow out a stagnant, musty smell as well. When the air conditioner is turned on it creates moisture which attracts bacteria, mold and odor. There are a couple of solutions to rid your air conditioner of unwanted stenches. If there is an odd, moldy smell that kicks in as soon as you turn your air conditioning on, you don't have to close your nose and bear it. More likely than not, you've built up some mold and mildew thanks to moisture in your AC system. This moisture occurs naturally, and is part of the car, but if left for too long it can create mold. As air pumps past the evaporator and into the car, it picks up mold spores, which feed on the moisture. Luckily, they are easy to clean, and your car will smell good as new. Aside from cleaning/replacing your cabin filter, turn on your AC on the HIGHEST HEAT setting to kill the odor causing bacteria.
