The hot air tank may be blocked, and the hot air is not hot. What should I do?

1, check the warm air in the car, and blow the heat from the warm air small water tank into the cab with a blower. If the air volume is insufficient or the distribution of cold and hot air is not good, the heat of the small water tank of the warm air cannot be radiated, and the temperature of the warm air cannot be increased. At this point, first check whether the filter element is dirty or blocked, clean it, and replace it in time if necessary.

2. Check the operation of each gear of the blower to ensure that each gear has sufficient speed. If the knob is set to the warm air position, the air volume is large enough and the wind direction is normal, and the cold air is blown out, check whether the cable of the hot and cold air control flap in the warm air box falls off, whether the warm air impeller is damaged, whether the flap falls off, etc. After troubleshooting, the warm air will get hot.

Extended data:

Warm air on the steps:

1. After the car is started, after about 8- 15 minutes, the water temperature rises to normal temperature, and the warm air can be turned on at this time. (that is, when the water temperature rises to the middle)

2. Adjust the circulation mode of the air conditioner to in-vehicle circulation.

3. Switch to warm air mode, some cars are in the red area, and some cars are represented by the sun.

Don't turn on the air conditioner (don't turn on the AC switch), because the warm air uses the thermal cycle of the car itself to save energy.
