There is no heating in the car, is there something wrong?

Hello, for the car without heating, first of all, you need to touch the warm air water pipe, whether it is hot or not, if the warm air water pipe is very hot, it means that there is a problem with the cold and warm conversion inside, and you need to check whether the motor of the cold and warm conversion is damaged.

Hello, there is no heater in the vehicle, this check whether the fan is normal, whether the air conditioner flap is normal and whether the air conditioning filter is dirty and blocked.

If the car has no heating, if it has just started because the water temperature has not come up, if the water temperature comes up or there is no heating, then the warm water tank is blocked, and it can be cleaned up generally.

Hello, if there is still no warm air after the water temperature of the vehicle rises, it is caused by the blockage of the warm air water tank or the failure of the cold and warm air transfer switch, and you need to go to the repair shop to check it to be sure!

Hello, first of all, it is recommended to check the thermostat, heater, control switch, and whether your heater water pipe is short-circuited

The car is not heated, check whether the heater system is faulty, this is mainly used for engine heating.

If there is no warm air, it is generally a small hot water tank that is clogged, clean the warm water tank, check the thermostat and water temperature sensor.

Hello, there is no heater, check if the water temperature is enough, the water temperature is too low, the heater must be no, and then check again. Whether the heater water tank is blocked, there is also such a problem if it is blocked.

If the car is not heated, it is likely to be a problem with the wiring, which has happened to my car, refer to it.

The heat of the car's heating comes from the heat dissipated by the engine. If there is no hot air after the car has been started for a period of time, it is a question of the air intake system.

If the water temperature is normal, there is no this, it should be that the thermostat is faulty, or the channel is blocked.

Hello, many reasons will cause this failure, it is recommended to read the manual first, see if your own operation method is right, if there is no problem, check whether the antifreeze is missing. It is recommended to find a master to take a look.

In your case, there should be a problem with the thermostat, and it is recommended that you can go to a local professional repair shop to check it.

Hello, if there is no heater for this phenomenon, it should be caused by the damage of the heater, and it is recommended to go to the repair shop for inspection and repair.

Hello, in this case, it is recommended to focus on checking whether the warm air tank is blocked. Determine if the switch is in the warm air position?

If the car turns on the heater normally and does not respond, it is recommended to consider the store to check whether the fan is broken and cannot blow normally.

There are many reasons for this, and it is recommended that you check with the auto repair shop to find out the cause, winter is coming soon.

Engine water temperature, heating pipe, heating switch, external circulation device, etc.

Reason: 1. Check whether the connecting plug of the heater line is loose, and find the plug and unplug it several times, and at the same time make the feed of the contact head piece rub off to achieve good contact.

2. Check whether the fuse (sheet) of the heater is heated and deformed, resulting in poor contact.

3. Whether the contact heater relay is good or loose.

Your question is very vague, what is the indication that the warm air cannot be turned on? If the fan does not rotate, you need to check the wiring and fan. If the fan is coming out normally, it depends on whether the water temperature is normal.

If the engine water temperature can reach more than 85 degrees, it is necessary to check whether the warm air water tank is blocked. Is the warm air outlet control mechanism flexible? If the heater is not in place, the heater will not come out.

It is recommended to go to the repair shop to have it checked.

The repair shop master will help you find out the reason.

Summary. Hello! 1. The lack of warm air may be due to the fact that the coolant temperature is still relatively low after the engine is just started, so the warm air will not blow out after turning on the warm air. Another possibility is that the heater water valve and heater tank are faulty, which will also cause the car air conditioner to fail to heat.

2. The heating principle of automobile air conditioner is very simple. When heating, the high-temperature coolant in the engine will flow through the warm air box, and the air blowing from the blower will also pass through the warm air box, so that the air outlet of the car air conditioner can blow warm air.

3. The heater box is a heat exchanger, which is a key component of automobile air conditioning and heating.

4. If the heating tank fails, it will cause the car air conditioner to fail to heat.

5. When the car engine is just started, the temperature is relatively low. At this time, it is not possible to blow out a warm air by turning it on. At this time, turning on the warm air will also slow down the temperature rise of the engine, which will lead to a decrease in engine power and an increase in fuel consumption.

6. It is recommended not to turn on the heater when the engine is just started, and then turn on the heater when the car is driving normally for 10-20 minutes.

7. Automobile air conditioning can also be refrigerated, and the refrigeration principle of automobile air conditioning is also very simple. During the refrigeration process, the engine drives the compressor to run. At this point, the compressor can continuously compress the refrigerant and deliver it to the evaporation tank.

The refrigerant can expand and absorb heat in the evaporation chamber, allowing the refrigerant to cool the evaporation chamber.

8. The cooling evaporation box can cool the air from the blower.

The car does not have a heating and sometimes breaks down.

The absence of warm air may be due to the fact that the engine has just started, and the temperature of the coolant is still relatively low, and the warm air will not blow after turning on the warm air. Another possibility is that the heater water valve and heater tank are faulty, which will also cause the car to run empty and not heat.

Heating of automobile air conditioners uses the heat of the engine. The principle of additive virtual heat in automobile air conditioning system is very simple. When heating, the high-temperature coolant in the engine flows through the warm water tank, and the air from the blower also passes through the warm water tank, so that the air outlet of the car air conditioner can blow warm air.

The warm water tank is the heat exchanger, and this component is the key component of the air-heat modulation of the company.

If the heater tank fails, the car will not be heated.

When the engine of our car starts, the temperature is relatively low, and it is impossible to blow warm air when the heater is turned on. Turning on the heater at this time will also slow down the temperature rise of the engine, resulting in a decrease in engine power and an increase in fuel consumption.

It is recommended not to turn on the heater when the engine is just started, and to turn on the heater when the car is running normally for 10-20 minutes.

Car air can also be used for refrigeration, and the refrigeration principle of car air is also very simple. When cooled, the engine will drive the compressor to run. At this point, the compressor can continuously compress the refrigerant and deliver it to the evaporation tank.

The refrigerant can expand and absorb heat in the evaporation chamber, allowing the refrigerant to cool the evaporation chamber.

The cooling evaporation tank cools the air blown out by the blower.

Take out the co-pilot box, you can see that there are 3 motor actuators, close to the fan is used for internal and external circulation switching, and 2, to distinguish by yourself, such as point defogging, Bitan where there will be something turning, that is the wind direction actuator, adjust the temperature to see if the last execution letter is good whether it has movement, if not, manual remorse code turn around, luck is just stuck, luck is generally abnormal can be dismantled and repaired.

The reasons why the car has no heating are as follows: 1. The warm air tank is blocked and the skin is destroyed. The internal structure of the car's heater tank has many small heat dissipation pipes, so it is easy to cause internal blockage.

Scale, impurities, flocculents, sediment, etc. contained in the coolant may cause clogging. After the warm air water tank is blocked, the flow rate of the coolant inside the warm air water tank will slow down, the flow rate will also become smaller, the heat supply will be insufficient, and the air conditioner will naturally not be hot. 2. Thermostat failure.

If you use the car in the northern winter, the water temperature will be low for a long time, and it will not go up, and the air conditioning heater is naturally not hot, and the gauge can also be seen from the water temperature gauge that the gauge is significantly lower than the normal scale. 3. The heating valve is faulty. After the failure of the heating water valve, the opening of the electronically controlled valve is no longer controlled by the computer, and is in a state of normally open, normally closed or a certain position is not moving, at this time, the warm air tank has no coolant flow dust or the flow is not controlled, and the temperature of the air conditioner is naturally uncontrolled.

The heating valve is actually an electronically controlled valve. The warm water valve is installed between the inlet pipe of the warm air tank and the small circulation pipeline of the engine, and the valve switch is controlled by the air conditioning computer to control the flow of coolant into the warm air tank, so as to achieve the purpose of more accurate control of the temperature of the air conditioner.

The main heat of the car heating is the heat of the engine, mainly through the coolant circulation device to deliver the warm air to the car, if the heating is not hot, you should check whether the water temperature of the engine is normal, whether the heating pipe is blocked.

When the heating system is turned on, the heat of the small water tank of the warm air is blown into the cab by using the blower, if the air volume is not enough or the hot and cold air is not well distributed, the heat in the warm air tank can not be dissipated, which will cause the temperature of the heating system to not rise, in this case, you should check whether the filter is blocked, and also check whether the warm air box is faulty.

Another reason is that the thermostat is always on, or because the thermostat is turned on too early, if the cooling system is circulated too early, the outside air temperature will decrease, and the outside cold air will soon cool the antifreeze, so that the water temperature of the engine is difficult to rise, and the warm air will not be hot.

The air resistance of the engine cooling system will also lead to the reduction of the circulating working state of the cooling system, resulting in the phenomenon that the water temperature rises and the heating system is not hot.

The main heating of the car is the heat of the engine, which is mainly delivered to the car through the coolant circulation device. If the heating is not hot, check whether the water temperature of the engine hole is normal and whether the heating pipe is blocked.

When the heater system is on, the blower is used to blow heat from the small heater into the cab. If the air volume is insufficient or the hot and cold air is not well distributed, the heat in the heater box cannot be dissipated, which will cause the temperature of the heater system to not rise. In the case of this locust wilt, you should check whether the filter is clogged and also check whether the heater box is faulty.

Another reason is that the thermostat is always on, or the thermostat is turned on too early. If the cooling system circulates too early, the outside temperature will drop and the outside cold air will quickly cool the antifreeze, so that it is difficult for the engine water temperature to rise and the warm air will not be hot.

The air lock in the engine cooling system can also reduce the circulating operation of the cooling system, causing the water temperature to rise, but the heater system is not hot. In this case, the warm air open lead box should be replaced in time to ensure the normal operation of the warm air system.
