The method of turning on the warm air in a car air conditioner is as follows:
1. If it is an automatic air conditioner, you can directly increase the temperature. That is, the larger the number displayed, the higher the temperature.
2. If it is a manual air conditioner, turn on the air conditioner switch, switch the AC button to the position where the AC light is off, and then turn the hot and cold knob to the red direction to the end.
Precautions for turning on the air conditioner in the car
1. Do not turn on the heating and air conditioning immediately when the car is hot. Be sure to wait until the water temperature in the engine water tank rises before turning on the heater.
2. If the car windows are foggy, the warm air speed should be increased.
3. Do not turn on the AC button. The AC button is the air conditioner compressor switch. Warm air is generated by the car's own heat cycle and does not require the compressor to work.
