How can the car heater not be hot? The reason why the car heater is not hot

Depending on your problem, it may be that the engine temperature can't keep up.

Automobile air conditioning device is referred to as automobile air conditioner. It is used to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment in the best state, provide a comfortable riding environment for the occupants, and reduce the fatigue of the journey.

What is the reason why the car heater is "not hot"?

Here's why:1. The vehicle's heater switch is faulty;

2. The air conditioner filter is too dirty and cannot be ventilated;

3. The heater and dismantling machine are faulty; 4.damage to the engine's thermostat;

5. There is a shortage of antifreeze;

6. The antifreeze needs to be replaced when the replacement cycle arrives;

7. The antifreeze circulation pipeline of the vehicle is blocked.

The reasons why the car heater is not hot and how to solve it are as follows:

1) The speed of the blower is slow or not, the blower motor and speed regulating resistor should be checked for damage, and if so, it should be repaired or replaced.

(2) The water channel is blocked: the dredge water pipe should be checked, and the radiator should be replaced if necessary.

3) The connection of the water pipe joint falls off or the water valve fails: connect the falling off pipe mouth and replace the failed water valve.

4) The temperature damper cannot return normally: adjust the temperature damper according to the regulations, and replace new parts if necessary to make the temperature damper return normally.

The reason why the car heater is not hot - a problem with the cooling system

First, the thermostat is always open or the thermostat is turned on too early, so that the cooling system is prematurely circulated, and the external temperature is very low, especially when the car is running, the cold air quickly cools the antifreeze, the engine water temperature does not rise, and the warm air will not be hot.

Second, the impeller of the pump is damaged or lost, so that the flow through the small tank of warm air is not enough, 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 unhot warm air. If there is always gas in the cooling system, it is likely that the cylinder head gasket is damaged and the gas is being pumped into the cooling system. If the inlet pipe of the small warm air tank is hot and the outlet pipe is cold, this situation should be that the small warm air tank is blocked.

The small water tank for warm air should be replaced.

If there is a blockage, clean it. If there is no blockage, then you check whether the inlet and return pipes of the heater are hot, and the heat of the water pipe means that the position of the wind shield in your heater is not correct, and the wind direction cannot be divided according to your requirements. If it's not hot, the warm air tank is blocked.

Here's why:1. The vehicle's heater switch is faulty;

2. The air conditioner filter is too dirty and cannot be ventilated;

3. The heater and dismantling machine are faulty; 4.damage to the engine's thermostat;

5. There is a shortage of antifreeze;

6. The antifreeze needs to be replaced when the replacement cycle arrives;

7. The antifreeze circulation pipeline of the vehicle is blocked.

There are four possibilities for the car heater is not hot: the first vehicle cooling system lacks a certain amount of coolant, resulting in the cooling water can not be circulated normally in the warm air water tank, so that the warm air is not hot, the coolant in the second vehicle is not replaced in time in accordance with the provisions of three years and 60,000 kilometers, resulting in the phenomenon that the coolant can not be circulated normally due to the blockage of the warm air tank waterway, and the third is due to the fact that the air conditioning filter element is not replaced in time, and the impurities and dust on the surface of the air conditioning filter element affect the reduction of air intake. The air outlet is too small and the warm air is not hot, and the fourth kind of warm air tank has too much dust and impurities on the surface of the water tank to affect the passability of the air volume, resulting in the warm air is not hot. Among them, the third and fourth situations are the most likely to cause the warm air to not be hot, and the fourth situation needs to occur in the vehicle without air conditioning filter.

It is recommended that the vehicle coolant be replaced once every three years and 60,000 kilometers, and the air conditioning filter element should be checked once every 10,000 kilometers and replaced once at 20,000 kilometers.

The main reasons why car heaters are not hot are as follows:

1. Air conditioning system: The heating line of the air conditioning system has poor contact, which leads to the failure of the heating system to work normally.

2. Engine: The warm air of the vehicle is not hot due to engine cooling, because the warm air of the vehicle is mainly the engine heat of the vehicle, and once the engine is cooled, it will lead to the inability to heat.

Here's how to maintain your car air conditioner daily::

1. Air conditioning filter: It should be replaced regularly, especially in the north, which will affect the use of the filter.

2. Regular inspection: the height of the refrigerant liquid level, the simple way is to check with the lookout hole of the dryer, if the oil level is found to be too low, it should be added in time.

3. Condenser: There are often many foreign objects such as dust, mud, and leaves installed on the windward side, which will lead to the reduction of the working effect of the condenser for a long time, so it should be cleaned regularly.

4. High temperature: corrosion, vibration, impact, etc. are easy to shorten the service life of the air conditioning hose, the air conditioning system hose should be replaced regularly, and the air conditioning system hose and pipe joints should be checked regularly for oil stains.

5. Evaporator: The evaporator conduit should be clean, and the blower should be kept running normally, and the drainage pipe should be kept clean and unobstructed, so as to ensure that the condensate is discharged in time.

It's that the thermostat is broken, I just changed it a few days ago, there is a temperature when I park, and the water temperature falls off when I run at high speed, and the thermostat is broken when I remove it, and it's good to replace it.

Hello, the reasons why the car heater is not hot are: 1. The small water tank of the heater is blocked. After the small water tank of the warm air is blocked, the hot water does not pass through the small water tank, resulting in the phenomenon of no warm air.

2. The heater control panel is broken. If the heater switch is broken, it cannot transmit the corresponding warmer air signal, resulting in the phenomenon that the heater is not hot. 3. There is gas in the waterway.

There is gas in the waterway, resulting in insufficient heat ** and abnormal heating air.

The main reason is that the small water tank of the warm air is blocked, and the hot water does not pass through the small water tank, resulting in the phenomenon of not having a warm air, and the small water tank of the warm air is not blocked, resulting in the phenomenon of not having a warm air, and the blockage of the small water tank of the warm air may lead to the cold air that blows out, and the reason for this phenomenon is that the owner does not replace the antifreeze for a long time. If you do not clean the air conditioning duct for a long time, it is also easy to have a small heating tank blockage, it is recommended that the owner do a more comprehensive maintenance of the car's heating system before the winter comes.

When the owner turns on the warm air switch, due to the failure of the warm air switch, the corresponding warm air signal can not be transmitted, resulting in the phenomenon that the warm air is not hot, if the warm air is not hot due to the warm air switch, the owner needs to go to a professional repair shop or 4S shop for processing.

There is gas in the waterway, resulting in insufficient heat, abnormal phenomenon of warm air, there is gas in the waterway will not only make the warm air not hot, when the situation is serious, it will also lead to other faults caused by high engine temperature, which needs to be dealt with by the owner in time, and when they can't deal with it, it is recommended to find professional maintenance personnel to deal with it.

Hello landlord, similar problems or go to 4S to check your estimated inspection and maintenance, go to the repair shop or 4S can try it.

Here's why:1. The vehicle's heater switch is faulty;

2. The air conditioner filter is too dirty and cannot be ventilated;

3. The heater is faulty; 4.damage to the engine's thermostat;

5. There is a shortage of antifreeze;

6. The antifreeze needs to be replaced when the replacement cycle arrives;

7. The antifreeze circulation pipeline of the vehicle is blocked.

The lack of heat in the car can be divided into two reasons: one is caused by the engine cooling system, and the other is caused by the poor operation of the control mechanism of the warm air. When repairing, we must first determine which cause is the cause, and then carry out the corresponding maintenance.

The specific reasons why the car heater is not hot:

1. Blockage of the small water tank of the warm air: the car heating system is not used for a long time, and the phenomenon of the warm air is not hot when used in winter, the main reason is that the small water tank of the warm air is blocked, and after the small water tank of the warm air is blocked, the hot water does not pass through the small water tank, resulting in the phenomenon of no warm air, and the blockage of the small water tank of the warm air may lead to the cold air blowing out, and the reason for this phenomenon is that the owner does not replace it for a long time.

2. Damage to the heating control panel: The heating control panel is damaged like the bulb control switch at home is broken, when the owner turns on the heating switch, due to the failure of the heating switch, the corresponding heating signal can not be transmitted, resulting in the phenomenon that the heating air is not hot, if the heating air is not hot due to the heating switch, the owner needs to go to a professional maintenance shop or 4S shop to deal with it.

3. There is gas in the waterway: there is gas in the waterway, resulting in insufficient hot gas, and the phenomenon of abnormal heating air, there is gas in the waterway not only will not make the warm air hot, but also lead to other faults caused by high engine temperature when the situation is serious, and the owner needs to deal with it in time.
