Why does an unpleasant odor occur?

Dust appears in the ventilation system, which mixes with the moisture of the evaporator, which creates a favorable environment for the multiplication of various fungi and bacteria. Frequent activation and deactivation of the climate control system prevents moisture from draining and evaporating through a special drainage hole. This allows the microbes to spread rapidly, especially in hot climates, which becomes the cause of an unpleasant odor in the car.
