What happened to the warm air?

Question 1: What is the reason why the car heater is not hot? There are two reasons why the automobile heating system is not hot: one is the engine cooling system, and the other is the poor operation of the heating control mechanism. In maintenance, we must first determine which cause it is, and then carry out corresponding maintenance. The method of discrimination is simple. Look at the temperature of the two inlet pipes of the warm air small water tank. If both pipes are hot enough, there is something wrong with the air flow control mechanism. On the contrary, if both pipes are cold, or one is hot and the other is cold, it is a problem with the cooling system.

Possible problems in the cooling system are:

First, the thermostat is often opened or opened too early, which causes the cooling system to make a large cycle prematurely, and the outside temperature is very low. Especially when the car is driving, cold air quickly cools the antifreeze, the engine water temperature does not come up, and the warm air does not heat up.

Second, the water pump impeller is damaged or lost, so that the flow through the warm air small water tank is insufficient and the heat cannot come up.

Third, the engine cooling system has air resistance, which leads to poor circulation of the cooling system, resulting in high water temperature and no warm air. If there is air in the cooling system all the time, it is likely that the cylinder pad is damaged and air leaks into the cooling system. If the inlet pipe of the small heating tank is very hot and the outlet pipe is very cold, this situation should be that the small heating tank is blocked. The small heater water tank should be replaced.

Question 2: What should Volkswagen Passat do if the warm air is not hot? Hello, if it's not hot in the south, it's mainly due to the blockage of the warm air tank or the actuator problem, you can modify it.

Question 3: What is the reason why the warm air of the van is not hot? Open the protective cover on the engine and you can see a glue pipe leading from the water tank to the heater. There is a switch on it. Just turn on the switch.

Question 4: What happened to the warm air of Chang 'an Star? There is a heater switch in front of the car ~ see if it is turned on. If it's not a tuyere, feel whether the warm air pipe is cold water ~ if it's cold, it needs ventilation! At the engine water pipe.

Question 5: Why is a set of central heating not hot? What should I do? Property is useless! They found that heating is king! It is estimated that it would be better to put water on it! But if you don't solve the fundamental problem, find someone to clear it!

Question 6: What happened to the warm air in Picari? Check whether a thermostat is installed and the size cycle is normal.

Question 7: What if Mazda 3 is not hot? On the right is the hot and cold control knob, pull down to the far right.

In the middle is the wind speed knob. Put it in third gear.

The wind is on the left, and it is best to blow glass in winter. In addition, Mazda 3 is heated by the operating temperature of the engine. It is normal that Leng Gang is not hot when it is turned on. Drive slowly for a while.

When the car is hot, there will naturally be hot air.

Question 8: What should Great Wall Motor do if the warm air is not hot? The reason why warm air is not hot is:

1, the engine water temperature itself is not high.

2. The circulating water to the heater is not turned on.

The heater doesn't work.

It is good to solve the above reasons.

Question 9: What if the hair dryer is not hot? Then the heater of your hair dryer is broken and can't be used normally. You can buy another one.
