What s going on with the car air conditioner without wind

This happens with car air conditioners, and in general, there are the following situations:

Fan fuse burned or air conditioning system control part insurance, speed control resistor, fan resistance failure, thermistor, etc.;

Some constant temperature automatic air conditioning automatic shutdown, when manually or automatically set to a certain temperature when the shutdown, is a normal phenomenon, but mainly depends on the car air conditioning design form.

If there is no cold air, such as refrigeration in hot weather, there are many aspects, such as refrigerant consumption, compressor, evaporator, etc., are all in the list of inspections.

Maintenance of car air conditioners.

Do not turn on the air conditioner in the car compartment for a long time when parking, as this may cause exhaust poisoning of the driver, thus endangering their life. Because the sealing of some cars is not enough, the exhaust gas emitted by the car when parking is easy to leak into the cabin, and the exhaust gas reacts chemically with the substances in the air conditioner, affecting the driver's health.

As the weather gradually gets colder, pay attention to whether the wind direction of the air conditioner is normal and whether the temperature regulation is normal when using the air conditioner. The air conditioning system's switch to control the wind direction and temperature sometimes fails, which may be a problem with the wiring or switch, so it is best to go to a professional car service shop to check it.

It is best not to smoke, put seafood or leftovers in the carriage. Because the odor produced by these things will be carried to the evaporation box of the air conditioner with the circulation of air, causing the odor of the cabin. And this odor cannot be eliminated and will affect the health of the people in the car.

Because of the cold weather, many car owners leave the air conditioner completely idle, in fact, even in very cold weather, the air conditioner should be started every 3 to 7 days to ensure that the car is in a normal lubrication state. In autumn, bacteria are more likely to grow in the car, and if the air conditioner is turned on abruptly in the winter when it needs to be warmed in the winter, dirty things attached to the air intake and other places will run into the car. Therefore, in autumn, car owners should also make the air conditioner more "sporty".

When using a car air conditioner in autumn, it is best to use the circulation system in the car, which can prevent the autumn leaves from getting involved in the air inlet of the air conditioner, so that the air conditioner can not achieve good results. Because it consumes more fuel when the air conditioner is turned on, so in the current cool season, if the air quality is better, you can leave the air conditioner on, open the window for ventilation, and save fuel.

Some car owners because they don't like the noise made when the air conditioner is turned on to high gear, so they rarely or never turn the air conditioner to a large air volume, in fact, the air conditioner will suck in a lot of dust when it is used, and the regular opening of the wind can blow out the floating dust on the inner surface of the air conditioner, which is a simple way to keep the air conditioner clean.

If the air conditioner does not ventilate, it is generally because the air conditioner filter is blocked, or the blower is broken.

Answer: Glad to serve you, please wait, I need a few minutes to collect information or write an answer to your message, wait patiently, if there is anything inconsiderate, please understand

It is not excluded that it is a filter, there is too much dust.

You first take apart the filter, turn on the air conditioner, and see if there is any wind.

Ask what is going on with this sign, and there will be a while and there will be no for a while.

This shouldn't have been reported as a failure**, right?

Is there a fault**?

Ask Oaks Air Conditioner Speed Man.

Compressor failure, four-way valve failure, circuit failure.

It is necessary to inspect and disassemble the machine in detail.

400-826-8268 Air conditioner national after-sales service.

This is the official aftermarket repair of Oaks air conditioner**.

1. Blower failure:

Car blower is an important part of the air conditioning of the car, if in the process of use, the air conditioning compressor fails, the car air conditioner will definitely not ventilate, the internal coil of the blower is overheated or the capacitor is damaged is an important cause of the failure of the blower, you can turn on the car air conditioner to the maximum, listen to the sound of the blower, if it is determined that it is the fault of the blower, you need to go to the 4S shop to deal with it, it is difficult to solve it yourself.

2. The air conditioner filter is blocked

The air conditioning filter is an important reason for the air conditioner not to ventilate is also a more common factor, the car air conditioner in the process of operation, will absorb a lot of impurities in the air, so there is a blockage of the air conditioning filter, if the air conditioner does not ventilate, you can remove the air conditioning filter, check whether the car air conditioning filter is clean, if the air conditioning filter is too dirty, you need to replace it in time, you can go to the 4S shop or a maintenance shop, if you can solve it, you can also replace it yourself.

3. Control system failure

If the air conditioner's blower and air conditioning filter are not the cause of the car air conditioner's lack of wind, it may be that the damper, air conditioning computer or control switch is faulty, and the switch of the control system generally does not fail, it is recommended that the owner go to the 4S shop to check, so that it will be simpler to deal with.

Hello, the sudden lack of wind in the car air conditioner may be the following fault:

1. The blower is faulty, the blower is the core component of the air conditioner, if it is damaged, the car air conditioner will not be able to ventilate. The failure of the blower may be due to overheating damage or capacitor damage to the internal coil, and the sound of the blower can be judged by listening to the sound of the blower by turning the air speed and volume of the car air conditioner to the maximum. Once there is a fault, it is necessary to go to a 4S shop or repair shop to repair it, and it is not possible for ordinary people to do it themselves.

2. The blockage of the air conditioning filter is one of the above-mentioned causes of air duct blockage, and it is also the most common one. The air outside the car will be filtered by the air conditioning filter before entering the car, which will absorb a lot of debris in the air, so it is easy to clog. You can remove the air conditioner filter to see if it is clean, and if it is too dirty, you can replace it yourself.

3. If the control system fails, if it is not for the above two reasons, it is a problem with the control system of the automobile air conditioner. Dampers, control switches, and car air conditioning computers may all be the cause of failure, which is difficult to judge and difficult to repair by yourself. If you encounter it, you should go to the 4S shop to repair it.

4. The internal and external circulation of the air conditioner should be switched between use, as the name suggests, the external circulation is to let the outdoor fresh air enter the car, and the air in the car is discharged to the outside of the car. In the process of driving, if the internal circulation is always turned on, the air in the car will not be able to circulate normally, so that everyone will be choked by the unpleasant smell, and in serious cases, it may also lead to motion sickness and other phenomena for passengers in the car.

Precautions. 1. Close all the windows during the air conditioning, sometimes the air conditioning will feel a little hot in the car, some people will choose to open the windows half, so that the temperature in the car is suitable, but this will make the air conditioning load pressure too large. In the case of fuel consumption, it is not always possible to achieve the best effect, in this case, you only need to adjust the air conditioner according to your actual situation, and the practice of opening the skylight for ventilation may have the opposite effect.

2. Don't turn on the air conditioner after the car is parked for a long time, if your car is parked for a long time, the closed space will make the air in the car turbid, and even produce some unpleasant smells, so you should open the external circulation after getting into the car, and then turn on the air conditioner after the unpleasant smell is completely discharged.

Especially in a car parked under the sun for a long time, you can't turn on the air conditioner immediately after getting into the car, because the temperature in the car is very high, and the speed of still turning on the air conditioner to cool down the hot air is not as fast as opening the window to let the car change its own air, or you can try to open and close the door continuously to let the hot air in the car out.

The car air conditioner suddenly stopped winding.

1.The sudden failure of the car air conditioner may be caused by a broken temperature sensor on the evaporation tank, or a broken variable displacement valve on the compressor, which will cause the compressor to be in a working state all the time, which will easily lead to the compressor freezing.

2.The wind blown by the blower has to pass through the evaporation box to get cool, if the evaporation box is frozen, then there is no way to pass through the blowing wind, in this case, you can only hear the blower working, but there is no wind blowing out in the car, this is because the wind is blocked by the evaporation box, when the air conditioner is turned off, the ice slowly melts, in this case, the air conditioning wind can blow out again.

3.It should be noted that there are many reasons for the freezing of the evaporation tank of the air conditioner, the most common is that the variable displacement valve of the compressor is broken, or it is caused by the excessive fluorine filling of the compressor, which needs to be repaired in time.

4.It is worth mentioning that before the air conditioner is filled with fluoride, the vacuum inside must be removed, and then charged according to the standard amount of fluorine used in your vehicle.

5.The temperature sensor is a more important component, after the temperature sensor is damaged, it cannot be detected that the evaporation box is about to freeze, so the compressor has been working, which will cause the evaporation box to freeze.

Check the fuse relay, cabin air filter. There are several reasons why the car air conditioner does not ventilate:

1.Check whether the air outlet switch is connected properly and whether there is a short circuit.

2.Check the fuse of your air conditioner to see if it has burned out.

3.Check if the air outlet of the air conditioner is blocked.

4.Check if the air conditioner motor fan is working properly.

5.Check the power distribution of the whole vehicle and check the battery.

Hope it can be adopted, thank you.

1. Blower failure: the reason is that the internal coil is overheated and damaged or the capacitor is damaged;

2. Blockage of the air conditioning filter: The air outside the car enters the car after being filtered by the air conditioning filter, and at the same time, it will also absorb a lot of debris in the air, which is easy to be blocked;

3. Control system failure: damper, control switch, air conditioner computer failure.

First, it may be that the fan is not running, look for the fuse, find the fuse against it, and see if it is burned.

Second, the fuse on it is not broken, and the control knob or switch of the vehicle's air conditioning fan is broken.

It should be that the car blower is damaged and malfunctioning. It's also possible that the aircon filter is clogged.

It is caused by a malfunction in the air conditioning circuit.

The scope of the problem description is large, which can be analyzed and judged from the following aspects:

a. Blower failure;

b. Fan insurance burnout or air-conditioning system control part insurance, etc.;

c. Speed control resistance, fan resistance failure, thermistor, etc.;

d, some constant temperature automatic air conditioning automatic shutdown, when manually or automatically set to a certain temperature when the shutdown, is a normal phenomenon, but mainly look at the car air conditioning design form, with it as a reference.

e. If there is no cold air, such as refrigeration in hot weather, there are many aspects, such as refrigerant consumption, compressor, evaporator, etc., which are all in the list of inspections.

f. Air conditioning control part: divided into manual and automatic, depending on the model design, when there is a problem in the control part, it is also likely to lead to a windless state;

g. Air conditioning duct obstruction;

h. Air conditioning grid failure, such as dirty;

i. The fan motor is burned or the contact is poor or the rotation is weak;

j. Thermostat detection (perceptron) failure;

k. Reason for air-conditioning line;

l. If there is no heating air, it is possible: water temperature sensor (water temperature or engine temperature), thermostat, water pump circulation and other components or water circulation system; In addition, whether the heating water tank is blocked or not are all checked;

m. The possibility of other faults is not ruled out.

The air-conditioning system involves more parts and components, the development of modern automobiles is getting faster and faster, and the air-conditioning system is becoming more and more complex.

Because it's hot, and then you run for a long time, if it's 21 degrees, and then it suddenly jumps to 16 or 7 degrees, the air conditioner will frost, so it won't get windy.

Check yourself first, whether the fan switch is turned off, whether the air outlet is turned to other gears, and then listen to whether the fan has a sound, if there is no fuse, the fuse may be burned, then you have to enter the factory to check.

Caused by frost in the air conditioning pipeline, the pressure regulator should be replaced, if not, the compressor can only be replaced. You can try changing the refrigerant first.

Drive straight to the car detailing shop and you're done.

Check the fan's motor.

Useful to give good reviews, thank you.

Check the safety and speed control resistance of the fan.

Car air conditioner only wind, not refrigeration reasons and solutions:

1. The lack of refrigerant leads to insufficient refrigeration dose in the pipeline of the air-conditioning system, the pressure decreases, and the heat taken away becomes smaller, which will give you a feeling that the air conditioner only blows the air and does not refrigerate, then you need to observe from the sight glass above the drying tank, when the air conditioner is running normally, if there are continuous slow bubbles in the sight glass, the surface refrigerant is insufficient. If there is a significant bubble flipping, it means that the refrigerant is seriously insufficient.

In the absence of refrigerant, the solution is naturally to replenish the refrigerant, but it should be noted that if it is added from the low-pressure side, it is forbidden to pour the refrigerant bottle; If added from the high-pressure side, the engine is not started.

2. Too much refrigerant will also cause the air conditioner to not refrigerate. Because the proportion of refrigerant to the volume in the air conditioning system is required. If the proportion is too large, it will affect its heat dissipation, and similarly, if too much cooling oil is added during maintenance, the heat dissipation of the refrigeration system will also decrease.

Solution: Observed from the sight glass above the drying tank. If you can't see a single bubble in the sight glass when the car air conditioner is running, and there are no bubbles after the compressor stops, it must be too much refrigerant.

If there is too much pressurized cooling oil, cloudy air bubbles can be seen in the sight glasses when the air conditioning system is running normally. Of course, if there is too much refrigerant, you can slowly release some of it at the maintenance port on the low-pressure side of the air-conditioning system.

3. The drive belt of the automobile air conditioning compressor is relaxed, and the compressor will slip when working, which will cause the transmission efficiency to decrease, so that the speed of the compressor will decrease, and the delivery of compressed refrigerant will decrease, resulting in the non-refrigeration of the automobile air conditioner.

If the compressor drive belt of the automobile air conditioner is too loose, it should be tightened at this time, if it is flipped by hand, it means that the drive belt is too tight, and it should be slightly loosened. Of course, if the fastening is ineffective or the drive belt has cracks and aging damage, a new drive belt should be replaced.
