Jetta warm air is not hot. Why?

If the Jetta heater of Pacific Auto Network is not hot, you can first check whether the heater mode is selected on the air conditioning control panel. It is also possible that the heater water tank pipe or heater valve of the air conditioner is blocked, or the windshield in the air conditioning system is stuck or falls off, thus affecting the lack of the heater. If there is something wrong with the heater control system, you must go back to the 4S shop for inspection and maintenance.

The automobile heating system can realize the functions of heating, defrosting and adjusting temperature and humidity. In cold winter (even in late autumn and early spring), the automobile heating system can provide heating for the automobile and increase the temperature inside the automobile. In winter, spring and autumn, when the air humidity is high and the temperature difference between the inside and outside of the car is large, frost and fog will form on the window glass, which will affect the driver's sight and is not conducive to driving safety. At this time, turning on the heating system can remove the frost and fog on the window glass.

The vehicle heating system is not hot, which is divided into two reasons, one is caused by the engine cooling system, and the other is caused by poor operation of the heating control mechanism. During maintenance, it is necessary to determine which side has problems, and then carry out corresponding maintenance. The judgment method is also relatively easy. Check the temperature of the two intake pipes of the small warm air tank. If both pipes are hot enough, there is something wrong with the air volume control mechanism. If both water pipes are cold, or one is hot and the other is cold, it is a cooling system problem. (Photo/Text/Photo: Pacific Auto Network Cao Bo)
