Why is the Dongfeng Tianlong heater not hot? Thanks

The common reasons why the heater is not hot are as follows:

1. The small heater water tank is clogged:

The car heater system may not be used for a long time, which may occur during winter use. The main reason for the phenomenon that the warm air is not hot is because the small warm air water tank is clogged. After the small warm air water tank is clogged, hot water does not pass through the small water tank, resulting in no warm air. The clogged small warm air water tank may cause blowing out. It's cold wind. The reason for this phenomenon is that the car owner has not replaced the antifreeze for a long time. If the air-conditioning ducts are not cleaned for a long time, the small heater water tank may become clogged. It is recommended that car owners perform comprehensive maintenance on the car's heater system before winter comes.

2. The heater control panel is damaged:

The heater control panel is damaged just like the light bulb control switch at home is broken. When the car owner turns on the heater switch, due to the failure of the heater switch, The corresponding heater supply signal cannot be transmitted, resulting in the phenomenon that the heater is not hot. If the heater switch causes the heater to be lukewarm, the car owner needs to go to a professional repair shop or 4S shop for processing.

3. There is air in the water channel:

There is air in the water channel, which leads to insufficient supply of hot air and abnormal warm air. The air in the water channel will not only make the warm air not hot, When the situation is serious, it will also cause the engine to be overheated and cause other faults, which require the car owner to deal with it in time. If he cannot handle it himself, it is recommended to find a professional maintenance personnel to deal with it.
