Specific reasons and solutions of no hot air in automobile air conditioning
1. There are too many impurities on the air conditioner filter element, which will block the filter element and prevent the air conditioner from blowing hot air. The solution is to clean the air conditioner filter carefully. If the air-conditioning filter element is seriously blocked, it is recommended to directly replace it with a new air-conditioning filter element.
2. When the thermostat fails, it can well adjust the cooling capacity of the cooling system. When the thermostat fails, the temperature of water will be difficult to rise, making it impossible for the air conditioner outlet to blow out hot air. The solution is to repair the thermostat.
3. The warm water valve is in a fault state. When the warm water valve fails, the warm water valve will have two states, one is normally open and the other is normally closed, which will make the heating effect of the air conditioner worse. In severe cases, there is no hot air at all. The solution is to repair the warm water valve. If it cannot be repaired, it needs to be replaced with a new one.
4. The heater water tank is blocked. There are many radiating pipes in the heater water tank. If the owner doesn't take good care of it, these radiator pipes are very easy to block. The owner of the heater tank cannot operate if it is blocked. Need a maintenance master from the repair shop to clean it.
