Futian Ou Ma s5 has no warm air.

The filter is dirty and blocked, so the warm air can't get out.

The warm air of Futian Omoco s5 blows the heat of the small warm air tank into the cab through the blower. If the air volume is insufficient or the distribution of cold and hot air is not good, the heat of the small warm air tank will not be radiated, and the temperature of the warm air will not come up.

Under the long-term internal circulation mode of warm air conditioning, the air inside the car is not fresh, especially the space inside the car is not large, so the air conditioning inside the car must pay attention to regular window ventilation in winter.
