The main reasons why the warm air is not hot are: 1, the filter element of the vehicle air conditioner has not been replaced for a long time, which leads to its blockage by impurities; 2. The water pump impeller inside the air conditioning system is damaged or lost, resulting in insufficient water tank flow and unable to deliver warm air; 3. The water pressure can't reach the standard value or the waterway is blocked, resulting in insufficient power for the warm air. When using Volkswagen Magotan heater, the operator should pay attention to the following matters: 1. Don't let warm air blow against your head. Blowing warm air for a long time will directly lead to driver fatigue and greatly affect driving safety. Therefore, the correct way to use it should be to blow warm air at the place where no one is there, open the window a little and keep the air circulating; 2. Turning on the heating for a long time will lead to the growth of bacteria in the carriage, so when using the air conditioner, try to avoid smoking in the carriage.
