What should I do if the Mazda6 air conditioner is not cooling?

1. After the above steps of adding refrigerant are completed, try the refrigeration effect of the air conditioner, if it is still not refrigerated, it is likely that the refrigerant in the air conditioning system is insufficient. The refrigeration effect is poor because less refrigerant is injected into the evaporator from the expansion valve, resulting in the refrigerant absorbing less heat. At this time, the refrigerant should be added, but it is important to note that the refrigerant bottle should not be held upside down.

2. Clean the condenser and filter screen The condenser inside the air conditioner is too dirty, and it needs to be cleaned in time. It is not difficult to clean the condenser, when washing the car at home, prepare a bucket of water first, scrub it carefully with a rag, and mainly remove the dust stains on it.

3. There is also a blockage of the filter screen of the air conditioner, resulting in the situation that the air conditioner of the car is not refrigerated, at this time we have to clean the filter screen of the air conditioner, if the filter screen is seriously damaged or the service life is up, directly replace it with a new one.

The reason why the horse 6 air conditioner is not refrigerated is that there are many different refrigeration effects for you, so when people are repairing, the maintenance methods that need to be carried out are also different, so it is necessary to have a correct understanding, so as to be able to get a good improvement, and what to do if the car air conditioner is not refrigerated? Some of the maintenance methods introduced in the above text questions are very important, and you should know a lot.

The following points need to be checked when the air conditioner is not cooling:

1. Whether there is a refrigerant in the system, if not, it needs to be pressurized to check the leakage, and then add enough.

2. If there is refrigerant, check whether the compressor is working. If it is not working, you need to check whether there is any problem with the air conditioner pressure switch, temperature control switch and its wiring.

3. Check the heat dissipation of the air conditioner to see if the fan is working. Clean the condenser.

4. Replace the air conditioner filter, the filter element is too dirty, and it will also cause no refrigeration.

1. It may be the lack of refrigerant, if the air conditioner wants to work normally, it needs "fluorine", which is what everyone calls refrigerant, in fact, the refrigerant will not be consumed by itself if there is no man-made accident such as rear-end collision.

2. It may also be that the condenser is too dirty, the water tank and condenser of the vehicle need to be treated for heat dissipation, if the heat dissipation performance is not good, it will not only affect the refrigeration effect of the air conditioner, but also cause the engine temperature to be too high. Therefore, when the air conditioner is not cooled, it is necessary to check the relevant heat dissipation equipment of the vehicle.

3. It is also possible that the compressor belt is too loose and the air conditioner is not refrigerated, and many people will ignore the belt as a part, if the belt is not replaced regularly, there will be no assistance, abnormal noise, etc., which will affect the refrigeration effect of the air conditioner. Generally, when you go to the 4S store for relevant maintenance, the relevant staff will remind you to replace it.

Tips for using car air conditioners.

1. The timing of turning on the air conditioner. Regardless of whether the temperature in the car is very high or it is not exposed to the sun in the garage, after more than ten seconds of ignition, you can turn on the air conditioner immediately after the speed stabilizes a little.

2. The timing of turning off the air conditioner. Turn off the AC switch of the air conditioner two or three minutes before you arrive at your destination, and leave the air volume switch off at this time to let the blower continue to blow air. Doing so allows the air to dry the evaporator and prevent the growth of bacteria.

1.Refrigerant leaks. (It is manifested that the internal and external machines are working, and the compressor is also working, but it is ineffective).

2.The compressor capacitor is damaged or defective, causing the compressor to not work. (The phenomenon is similar to the above, but the compressor does not rotate and overheats).

3.The resistance value of the temperature sensing head at room temperature changes, resulting in the air conditioner not working. (The phenomenon is the same as when the air conditioner stops after reaching the set temperature).

4.Bad remote control or bad air conditioner receiver. (Manifested as no reflection of the air conditioner when it is turned on, or it does not work from time to time).

Step 5Four-way valve (single chiller does not have this failure) or compressor high and low pressure string, air conditioning works but has no effect. (The phenomenon is the same as the first one).

Step 6The failure of the control panel of the internal or external unit of the air conditioner causes the air conditioner to not be refrigerated. (Manifested as no reflection when turned on or the air conditioner is messed up).

7.The power supply of the air conditioner is reversed. (This failure occurs in a small number of air conditioners, usually at the time of installation).

8.The internal or external fan is damaged (the capacitor is more broken), and the external fan is damaged by the high exhaust temperature or high voltage protection. If the fan of the internal unit is bad, the internal machine is frosty, the external unit has been working, and the internal machine will condense ).

First of all, it is normal for high-pressure air to appear when the refrigerant is released, and the compressor and refrigerant you said are normal, and occasionally it will be easy to use. I don't know if your car is an automatic temperature control air conditioner (set the temperature and the computer automatically adjusts the refrigerant flow) If so, then it is good for the reason of temperature control, generally the sensor fails, or there is dirt around the sensor to interfere with the temperature, and the automatic adjustment of the air conditioner is generally not broken. There are many reasons for temperature control.

Put the refrigerant must be high-pressure air, and the refrigerant only appears when the high pressure is put (but be sure to put it when the car is cold in the morning, the high-pressure pressure is very high), see if you add more refrigerant, so that the air conditioner will work for a while and will not work for a while (this is a good difference, open the cabin to see if the fan is always rotating or not turning, the air conditioner must be no problem when it has been turning, and the refrigerant is more when it is not turning, and you touch the low-pressure pipe is not cool? If it doesn't work, you go to the small shop to put out all the fluorine, vacuum, I remember that I added 2 cans of car servants, 3 cans can't be added, remember to add fluoride oil.

I can only help you here.

It's just that the refrigerant is gone, so go to the 4S store to charge it. It's cheap and it's also standardized, so you don't have to worry about it later.

There can be a variety of reasons why the Mazda6 air conditioner is not cooling, and the common problems are as follows:

1.Air conditioner compressor failure: If the air conditioner cannot be refrigerated, you first need to check whether the air conditioner compressor is normal. If the air conditioner compressor fails, the refrigeration process cannot be completed and the air conditioner compressor needs to be replaced.

2.Insufficient or leaking refrigerant in the air conditioner: Insufficient or leaking refrigerant in the air conditioner is also one of the reasons why the air conditioner is not cooling. In this case, it is necessary to add sufficient refrigerant and test and repair leaks in the air conditioning system.

3.Air conditioner evaporator failure: Dashou air conditioner evaporator failure will also affect the refrigeration effect. Evaporators are usually located inside the air conditioning system and require specialized expertise to repair or replace.

4.Air Conditioning Circuit Failure: Air conditioning circuit ridge failure may cause the air conditioner to not function properly. In this case, it is necessary to test the circuit with a multimeter to find the cause of the fault and repair the circuit.

5.Air conditioner fan failure: Air conditioner fan failure may cause insufficient air flow, affecting the effect of air rolling town digital adjustment. The air conditioner fan needs to be inspected for damage or blockage, and if there is a problem, it needs to be repaired or replaced.

The above are some of the more common reasons why the Mazda6 air conditioner is not cooling, if you can't eliminate the fault by yourself, it is recommended to go to a professional car repair agency for repair and testing.

This can be caused by a lack of refrigerant or a damaged empty compressor. This is a midsize sedan from the Mazda 6 Mazda brand. It has a length, width and height of 4670mm, 1780mm and 1435mm, respectively, and a wheelbase of 2675mm.
