Why is the warm air not hot when the water temperature is normal?
Why is warm air not hot when the water temperature is normal?
1, the air conditioner filter screen is dirty and blocked, which will lead to much less wind blowing, thus affecting the heating effect of the warm air.
2. The thermostat is normally turned on or turned on too early, which leads to the premature large cycle of the refrigeration system. If the outside temperature is very low, the cold air will quickly cool the antifreeze when the car is driving, and the engine water temperature will not come up, and the warm air will not be hot.
3. The water pump impeller is damaged or lost, so that the flow through the warm air small water tank is not enough, and the heat cannot come up. There is air resistance in the engine cooling system, which leads to poor circulation of the cooling system, high water temperature and not hot warm air.
4. The car's warm air blows the heat of the warm air small water tank into the cab through the blower. If the small warm air tank is blocked, the heat of the small warm air tank will not be dissipated, and the temperature of the warm air will not come up.
5. If the knob is set to the warm air position, the air volume is large enough and the wind direction is normal, the cold air blown out may be whether the control flap cable of cold and hot air in the warm air tank falls off, whether the warm air impeller is damaged, whether the flap falls off, etc. If the heater water valve is damaged, the coolant may not enter the heater box, resulting in the heater not being hot. ?
