What is the reason why the warm air is normal and the water tank is not hot?

1, it is the simplest and most easily overlooked to consider whether the air-conditioning filter element has not been replaced for a long time, because if the air-conditioning filter element is dirty and blocked, it will lead to much less wind blowing and affect insufficient heat dissipation.

2, insufficient antifreeze: it will also affect air conditioning heating.

3. The warm air tank is blocked: antifreeze cannot enter the warm air tank or the flow becomes smaller, which will also affect air conditioning and heating.
