Most of the musty smell in the car is caused by improper maintenance of the evaporation box and condenser in the air conditioning system. This is mainly because the water in the evaporation box cannot be volatilized for a long time, which breeds bacteria.
How to avoid this problem. First of all, when the weather is not hot, roll down the windows on both sides of the vehicle and open more windows for ventilation to keep the air in the car fresh. Second, when driving with the air conditioner on normally, you can turn off the refrigeration pump before reaching the destination, but keep the air supply function on, and let the natural wind dry the water in the evaporation box. Third, due to more rain in spring and summer, cars often drive on some wading roads, which will cause the lower part of the air conditioner condenser to be contaminated with a lot of sediment. After a long time, the condenser will be rusted, thereby shortening the service life of the air conditioner. It is worth reminding that when cleaning, be careful not to knock down the condenser fins, let alone damage the tubes.
Good air conditioning quality mainly depends on the air conditioning filter, so it should be cleaned and replaced regularly.
Clean the truck air conditioner filter every 5,000 kilometers or 3 months, and replace the air conditioner filter every 20,000 kilometers or 12 months. Regarding the maintenance of the air conditioner filter, the air conditioner filter element is the filter of the air inlet of the car air conditioner. If it is not cleaned for a long time, the dust attached to it will blow into the car when the air conditioner is turned on.
