What to do if the car does not have a heater in winter, what happens if the car has no heater

There is no warm air in winter, it is considered in two situations, the premise is that the water temperature is up, at least 60 or more, confirm that the wind has been turned on, and the temperature is rotated to the hot air, 1 Observe whether the wind blows out of the air outlet, if there is no wind, the blower should be checked, 2 There is a wind blowing out, but it is cold air, you should check whether the hot air water pipe is normal, and the car heater mainly relies on the hot air water pipe to transport heat, so most of them are the problem of the hot air water pipe.

The lack of heat in the vehicle heating system 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 heating control mechanism. When repairing, we must first determine which cause is the cause, and then carry out the corresponding maintenance.

The method of judging is very simple, look at the temperature of the two inlet pipes of the small water tank of the warm air, if the two pipes are hot enough, it means that the air volume control mechanism is a problem, on the contrary, if the two water pipes are cold, or one is hot and one is cold, it means that it is a problem with the cooling system.

1.The air outlet does not come out of the air outlet, first of all, see whether the air conditioning filter is dirty and blocked. Turn on the blower, adjust the wind speed to the highest to see if the blower works, if the blower works, change the direction of the air outlet to see if the air is out, if the air is out.

2.There is no wind while the air is out, and there is no wind at the same time, which generally appears in the configuration of the dual-temperature zone air conditioner, and there is a circuit problem.

3.Ventilation but cool breeze This situation appears in a relatively old car, the car has been used for a long time without changing the antifreeze, antifreeze.

4.There is a warm air but it comes slowly or the effect is not good The reasons for this situation are that the antifreeze is not replaced in time, and the cold removal system is not cleaned.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

In winter, the car does not have a heater, you can add a diesel heater.

There are several possible reasons why the car has no heater:

1. The air conditioner blower is damaged.

2. The hot water valve or hot water valve vacuum drive fails.

3. The engine thermostat fails.

4. The heater water pipe is blocked or the heater core is fouled and blocked.

5. The air distribution pipe of the temperature control air conditioner is broken.

According to the above reasons, you can touch the two warm water pipes to test whether they are hot or not

1. If it is hot, it means that the water temperature is still no problem, and it is necessary to continue to check the cold and heat adjustment of the air conditioning panel.

If the water temperature is no problem, first of all, we have to adjust this adjustment to the hottest side, if it is adjusted to the hottest or not warm, it can be the door that regulates the heat and cold, there is a problem here, that is, the damper is not open or semi-open, if it is the motor adjustment, it may be that the motor is broken.

2. If you touch the warm water pipe and it is not hot, it may be a problem with the thermostat, it may be that it is opened too early, so that the water has not completely risen before the heat is dissipated, so it will cause no hot air or bad hot air, so we need to replace the thermostat with a new one.

Finally, we can also clean and clean the hot water tank to see if it is too dirty and clogged to circulate badly, this can dismantle the two water pipes and rinse them with a high-pressure water gun.

When the water in the engine flows through the warm air tank, the warm air tank is heated, the fan works, and the warm air tank is blown, and the wind is heated when it passes through the warm air tank, so the air outlet is the warm air.

The answer is that the warm air tank is clogged in the first place. The structure of the heater water tank is actually a reduced version of the engine water tank radiator, which is a number of small heat dissipation pipes, which are easy to clog as well as the water tank radiator. After the inside of the warm air tank is blocked, the coolant flowing through the tank slows down, the flow rate becomes smaller, the heat is insufficient, and the air conditioner heater is naturally not hot.

The second is the lack of coolant in the cooling system. Coolant is commonly known as antifreeze, and the heating air of automobile air conditioner comes from here, and the principle is different from that of household air conditioner heating. Automobile warm air circulation is a parallel pipeline in the small circulation pipeline of engine coolant, which is connected to the warm air water tank, and the blower blows the warm air water tank to produce warm air, which is how the air conditioning warm air comes.

The lack of coolant in the cooling system is the most common and easiest fault phenomenon that causes the warm air to not heat up.

Finally, there is the failure of the thermostat. The common fault of the thermostat is that it cannot be opened, but the reason why the heater is not hot due to the failure of the thermostat is that the thermostat cannot be closed, commonly known as the thermostat is always open. If the water temperature will be low for a long time in the northern winter, the air conditioning heater is naturally not hot, and it can be clearly seen from the water temperature gauge that the watch hand is significantly lower than the normal scale.

In addition, the low water temperature of the engine for a long time will lead to high fuel consumption and aggravated wear, so it is necessary to repair and check immediately when the water temperature is low for a long time.

In winter, how to solve the problem that the heater in the car is not hot?

1.In winter, the warm air in the car is not hot, probably because blocking the warm air box will cause the warm air to store too little water, and the natural wind through the warm air box cannot absorb enough heat, and the heating effect of the warm air is poor! If the antifreeze is cloudy, it will increase the probability of a clogged hot water tank!

If the blockage is light, it can be cleaned with a specialized machine. If the blockage is severe, you can only replace it with a new hot water tank! Under normal circumstances, the switching between warm and cold air is carried out through the control panel that controls the air duct of the hood.

If the actuator of the cold and warm air is stuck, the temperature cannot be adjusted and the warm air fails! Causes the warm air to not be hot.

2.The thermostat is often turned off, resulting in different water temperature cycles and excessive water temperatures. If the thermostat is always on, the water temperature meter will always be below 90°C, and the warm air is slightly warmer when idling, and the warm air is not hot at high speed!

Poor circulation of the water pump will directly cause the water temperature to be too high, and the problem of warm air will naturally be solved after replacing the water pump! The car has run away, the water temperature has come up, and the air conditioner is still not hot, not normal. Let's take a look at them one by one.

Air conditioner filters, warm water tanks, etc. It may be blocked there after a long time, and all kinds of debris will affect the heating effect of the air conditioner.

3.I can't feel the warm air, and the temperature in the car can't go up. At this time, the inlet and outlet pipes of the water tank in the hood are blocked.

If you have strong hands-on ability at this time, you can remove it yourself and rinse it with a hose. Why is it blocked? That's because the water at 80 degrees will produce limescale, which will block the flow of water for a long time.

If the water tank is not well circulated, it reflects that the temperature of the warm air in the car is not high and cannot be raised. Even if you don't do it yourself, you can drive to a roadside repair shop and instruct the repairman to do it. At least he won't give you any diagnostics or replacement parts.

Of course, the solution in the tank is not water, but coolant. Regardless of whether the heater is turned on or not, the coolant in the tank is circulating. That is to say, when you know this knowledge, you will never be deceived into changing the water tank, heater motor, water pump, etc.

You can clean the air outlet of the heater, or check whether there is any problem with the circuit of the heater, pay attention to maintenance, and pay attention to maintenance.

You can replace the air filter, replace the car thermostat, remove the inlet and outlet pipes of the heater water tank and clean it, etc.

Remove the heater in the car, clean it and reinstall it, and then start the heater in the car to generate heat.

You can check the status of the blower, you can check the filter element of the air conditioner, and you can check the motor. You can go to the 4S shop for repairs.

At this time, the outlet position of the air conditioner can be cleaned in time, and the temperature of the air conditioner can also be appropriately increased, and the coolant needs to be replenished in time, and the water volume of the water tank must be guaranteed.

What should be done is to go to the 4S shop for repairs, at this time it is very likely that there are some problems with the vehicle, so there will be such a situation where the warm air is not hot, and this time must be dealt with as soon as possible.

If it is not hot, the car should be heated for a while, indicating that the weather temperature outside is too low, so the car will not be able to get warm air for a while.

It may be that the engine is temporarily cooled, or there is some poor contact, at this time you can go to a professional car shop for repair, so that this problem can be well solved.

Hello, the reasons why the car heater is not hot are: 1. The small water tank of the heater is blocked. After the small warm air tank 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 producing warm air, and the blockage of the small water tank may lead to cold air, which is caused by the fact 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 easy to have a small water tank blockage without a draft, so 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.

1. The thermostat is often opened quickly or too early, so that the cooling system is prematurely circulated, and the external temperature is very low, especially when the car is driving, the cold air will quickly cool the antifreeze, the engine water temperature will not come up, and the warm air will not be hot.

2. The impeller of the water pump is damaged or lost, resulting in insufficient flow through the small warm air water tank and the heat does not come.

3. There is air resistance in the engine cooling system, which leads to poor circulation of the cooling system, resulting in high water temperature and not hot heating. If there is always air in the cooling system, it is possible that the cylinder gasket is damaged and the air is flowing to the cooling system; If the inlet pipe of the warm air small water tank is very hot and the water outlet pipe is cold, this situation should be that the warm air small water tank is blocked, and the warm air small water tank should be replaced.

The vehicle's heater switch malfunctioned.

The switch can be repaired, or there is a problem with the warm air running structure, which may be due to a clogged filter, resulting in insufficient air volume for the fan to blow into the car or unreasonable distribution of hot and cold air. At the same time, it is also necessary to check whether all the gears of the fan can reach a certain speed, and check whether the running damper of the cold stool to warm air is peeling off, and it should be repaired in time. The refrigeration system of the engine is subject to air resistance, which leads to the abnormal operation of the cooling cycle of the car, resulting in the problem that the warm air does not judge the heat.

Is it okay for a car to have no heater in winter? Isn't winter popular? A lot of people don't know yet.

Now let's take a look! 1.It's okay to turn off the heater in winter, but if you don't turn on the heater in winter, it will feel very cold in the car and will make you cold, so try to turn on the heater.

2.It's good for the performance of your mega circle car or for your health. As long as you don't turn it up too high, it won't cause some degree of impact on your interior glass. So feel free to turn on the heating. If you don't turn on the warm air, you will only be attacked by the cold.

The workaround for the car without heater:1. Check the hot and cold windshield to see if the air conditioner is adjusted to the hot windshield.

2. Check the temperature control switch of the electronic fan.

3. Check the water temperature thermostat. The lack of heat in the vehicle heating system can be divided into two reasons: one is caused by the engine cooling system, and the other is the poor work of the control mechanism of the warm wind.

Notes:When the engine coolant temperature is high and buried, the coolant flows through the heat exchanger in the heating system, and the air sent by the blower is heat exchanged with the engine coolant, and the air is heated and sent into the car by the blower through each air outlet.

This system is simple and reliable, requires no additional fuel, and produces hot water as long as the engine is working. However, it also has its obvious disadvantage, that is, it must be heated when the engine coolant temperature rises to a large cycle.
