Car Air Conditioning Problem 5, Car Air Conditioning Problem

If the car doesn't start, the engine won't run, the air conditioner and compressor won't work, and of course it's not cooling.

It's normal, and so is mine.

You said that it does not refrigerate when it is idle after starting. Check whether the refrigerant is enough, there is a drying bottle on the side of the condenser in front of the car, the sight glass can be observed, there are white bubbles is not enough, if the refrigerant is enough, it may be that the compressor is not good, and the compression is not enough.

The car doesn't start and the air conditioner compressor doesn't work so it doesn't refrigerate.

Check whether the outside of the condenser is dirty and clogged and the heat dissipation is not good.

Turn on the air conditioner at idle speed Check if the idle speed is rising.

If it doesn't start, the compressor doesn't work, it doesn't refrigerate, and it drives at high speed to refrigerate, which can only prove the heat dissipation problem, and it's OK to improve

There are many cases where the refrigeration effect is not good, if it is not refrigerated at all, it is easy to solve, this kind of preliminary suspicion that it is better than a few days and does not work is that the refrigerant has leakage, go to google to see an analysis of the reasons why the car air conditioner is not refrigerated is very detailed.

It is normal for the refrigerant effect at idle speed to be worse than the effect in operation, the engine speed is low at idle speed, the efficiency of the refrigeration system is relatively low, and the compressor is also improved at high speed, so there is no need to make a vivid analogy.

In the case of no driving you add the throttle to run for a few minutes to see the results.

If your air conditioner cools when your car doesn't start, that's a problem.

This is a motor problem, I also appeared last time, I did a good job in the 4S shop, I don't know if it will appear, I have seen a lot of riders have appeared like this, repaired or will appear again, worried!

Check it after sales, this problem is more professional, and there are professional technicians to solve it.

If the air conditioner fails, the main reason is that the compressor does not work and the air conditioner does not refrigerate, and it is recommended that you go to the local professional repair shop to check it before dealing with it.

Hello, if the car air conditioner is faulty, the air conditioning system of the vehicle is not cool, and it needs to be thoroughly checked and eliminated.

The failure of the car air conditioner has the compressor not working, or the air conditioner running without refrigeration, and the air conditioner has abnormal noise, which are all air conditioning failures.

Hello, if the general car air conditioner fails, one is that the refrigeration effect is not good, he just doesn't work, this, often.

In fact, there are many faults of automobile air conditioners, the most common is the problem of compressor, or the lack of refrigerant, etc., which affect the use of air conditioners.

There are many fault phenomena of this air conditioner, the most common is that the air conditioner is not refrigerated, and then there is a peculiar smell, including, compressor shaking, this phenomenon is relatively common, including, the condensate solvent can not be stored.

There are many faults in normal car air conditioning, such as the lack of compressor coolant** and so on.

The car air conditioner sometimes does not refrigerate and has no wind power, so it is necessary to go to the maintenance plant in time to repair and replenish the freon.

Hello. What are the reasons why car air conditioners are not cooling? Generally, the common causes of air conditioning not cooling are insufficient refrigerant.

The expansion valve is clogged or the evaporator piece is clogged. The condenser sheet is clogged or the system temperature is too high, and the refrigeration effect is poor. Air conditioning system piping leakage.

The pressure of the air conditioner compressor is insufficient. The fuse of the air conditioner is burned, the circuit is damaged, the circuit is short-circuited, or the connector is defective. The solutions are as follows:

1) Strengthen the maintenance of the components of the air conditioning system, and pay attention to the cleaning of the surface of the condenser sheet to ensure the heat dissipation effect;

2) Detect the system pressure to confirm whether the refrigerant filling amount and pipeline are unblocked;

3) Check whether the fuse and connector are working well.

In the case of a car air conditioner, there are multiple systems. Therefore, after all, it is an electronic product, and it is also easy to make problems.

The first thing to do is to see what the problem is, and whether there are any related faults**? Also, check if the refrigerant is missing? There is also whether the pressure of the air conditioning line is normal.

It is inevitable that the air conditioner will fail after a long time, such as low refrigeration efficiency or no refrigeration, and the fuel consumption will increase. Next, I will teach you a few ways to troubleshoot this problem simply.

1. The proportion of refrigerant in air conditioning is not coordinated.

At present, the refrigerants of air conditioners are all R-134A refrigerants, and the ratio of air conditioners to refrigerants has a range, which cannot be too much or too little. If the proportions are not coordinated, it will affect the heat dissipation performance of the air conditioner, and this problem can be monitored through the air conditioner pressure gauge.

2. The air conditioner filter is too dirty or even clogged.

When the car is driving with the air conditioner, it has to inhale the outside air into the cabin, but the outside air is mixed with harmful dust such as gray layer particles and peculiar smells, and the air conditioning filter can filter out these dirty things. However, after long-term use, the filter element may be blocked by these dusts, resulting in air inaccessibility, which affects the air conditioning refrigeration and increases fuel consumption, so it is necessary to check the air conditioning filter regularly.

3. The water tank and condenser are too dirty.

The water tank and condenser are used to dissipate heat, and they are located in the engine compartment at the front of the car. Limited by the current assembly process, there are small cracks in the engine cover, and the ash layer will fly in. If these two places are too dirty, it will affect the heat dissipation, on the surface the air conditioning system works normally, but the air conditioning refrigeration effect is not good, and the fuel consumption will increase.

Therefore, the inside of the engine compartment should also be cleaned regularly.

If these three aspects are normal after investigation, please send them to the car repair shop for investigation and repair!

Car air conditioners are easy not to refrigerate, the previous need to add refrigerant, the current one... Oh, you need to consult a professional teacher!

Air conditioning has gradually become an indispensable part of people's lives, bringing a lot of convenience to our lives. However, it can be found that in the process of use, the air conditioner will inevitably have this or that failure, so at this time, it is very necessary for people to understand the knowledge of common fault maintenance of air conditioner.

1) The smell of the air conditioner cannot be removed.

The air conditioner will pile up more things in the process of use, if you don't pay attention to hygiene, it is likely to have a peculiar smell, but under normal circumstances, the peculiar smell in the air conditioner can be effectively improved by cleaning and sorting out the debris, but sometimes there will be no way to remove the peculiar smell, at this time it is necessary to check whether the evaporator is in a normal working state, sometimes the evaporator is blocked, it is likely to cause a more serious peculiar smell. It is also possible to appropriately place grapefruit peel and other things with the function of daughter-in-law in the air conditioner.

2) The evaporator has a large water output.

In some families, it will be found that there will be a lot of water droplets in the evaporator of the air conditioner, and sometimes there will even be water accumulation, which is normal under normal circumstances, because there will be condensation in the process of air conditioning operation, and the moisture in the air will condense on the evaporator, but if there is a large amount of water, it is necessary to properly check the state of the evaporator, and at the same time, it is not forgotten that it is necessary to check whether it is because the temperature difference between the air conditioner and the indoor temperature is too large. If so, it needs to be adjusted to a certain extent, so as to effectively ensure the service life of the air conditioner.

3) The air conditioner is relatively noisy.

When the air conditioner is working normally, the sound is relatively small, but when the air conditioner has a certain failure, the air conditioner will often have a relatively large noise, generally check whether there is a problem with the motor or compressor of the air conditioner, and sometimes it is very necessary to check whether there is a problem with the air outlet of the air conditioner, if the air outlet is blocked, it is also likely to cause noise. If none of these problems are true, it is possible that there is a problem with the assembly of the air conditioner, and it is very necessary to check whether the installation between the parts of the air conditioner is reasonable according to the instructions, so as to effectively avoid unnecessary trouble.

Common faults of automobile air conditioners Problem performance: slow response, no refrigeration, easy water leakage in the car, abnormal noise; Typical models: Alto, Chang'an Star, Meiri, Jetta, A5, Qiyun Analysis and puzzles:

Chery auto maintenance experts said that the unsatisfactory refrigeration effect is a common problem of air conditioning, and the first thing that needs to be stated is that the effect of automobile air conditioning cannot be compared with household air conditioning. What is unsatisfactory? There is no uniform standard.

Generally speaking, under the condition that the doors and windows are sealed and the body is well insulated, the air conditioner runs for 30 minutes at the speed of 1000 rpm of the engine, and the temperature difference between the inside and outside of the car is 10 or more, and less than 10 can be judged to be a bad effect. You can first look at whether each fan is running normally, if there is no rotation, check the air conditioning electronic control box, see if the fuse and relay are burned out, replace it, and check whether the fan that does not rotate has burned out. If the fan is running normally, it depends on whether the condenser is dirty, and if the upper area is full of dust and sand, it will greatly affect the heat dissipation.

Rinse with clean water and turn off the air conditioner while washing. It should be noted here that the return windows of the condenser and evaporator should be cleaned frequently. In addition, air conditioners generally need to be refilled with refrigerant, refrigeration oil and filter drier after 1 year.

To do these maintenance, it is recommended that you go to a professional manufacturer or a reputable repair point to do it. Because ** is secondary, if you don't do it well, it will damage your air conditioner. If there is no response after the air conditioner switch is turned on, check whether the fuse of the electric control box is intact and whether the wiring harness connector is loose.

If the switch stops working after a while, first see if the condensing fan does not rotate, and check the fuse of the electric control box if it does not rotate. If the fan is normal, check whether the pressure in the system is abnormal, too high means too much refrigerant or blockage or poor heat dissipation of the condenser, too low means insufficient refrigerant or system leakage. Generally, the leak check is mainly around the condenser, because there are many joints and it is close to the ground, and the sand and gravel are easy to damage it.

If there is an abnormal noise during the operation of the air conditioner, you should immediately determine where it came from, and then stop the machine for inspection. It is mainly sent out by the compressor suction cup or belt, and the belt tensioner should be checked for damage or tilting, and if so, it should be replaced and installed correctly.

I didn't see the picture, according to what you said, the last two are blowing the front windshield at the same time blowing under the feet, and the other is blowing the front windshield alone. The number is the wind power switch. The connected keys didn't understand what you were talking about.

What car do you have?

**There is a picture, there is no picture for you to be confused, basically those are the few 4 blowing front windshield 5 glass and under the foot 1234 is the wind speed gear The two on the right may be AC air conditioning next to the inner circulation and outer circulation.

I didn't see the picture, and I don't know what the car is, so I'll tell you about it by feeling:

1.Air conditioner blowing mode switch (including blowing surface mode, blowing body mode, blowing foot mode, defrost and defogging mode, etc.), 4 and 5 should be defrost and defog mode.

2.The "0 1 2 3 4" in that circle should be the air volume level, which represents the setting of the air volume of the air conditioner from small to large.

3.The two buttons connected together on the right should be the air conditioner working mode. That is, general refrigeration (external circulation, air volume is self-set) and maximum refrigeration (internal circulation, maximum air volume).

1.The fourth is to blow the front windshield and the foot The fifth is to blow the front windshield.

It's wind speed gear, and gear 0 is off.

3.The upper button is the air circulation in the car, and the lower button is the rear windshield defogging.

Basically, every important component of the air conditioner has a problem, and there will be no refrigeration. If you want to find the cause accurately, you need the current condition of the air conditioner to make an accurate judgment.

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

2.Four-way valve (single chiller does not have this failure) or compressor high and low pressure string, air conditioning works but has no effect.

3.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 internal fan is bad, it is manifested as frost on the internal unit, and the external unit is working all the time, and the internal machine will condense).

Help you check the information, and the symptoms of your car are very similar, see if it is what you need, if you feel satisfied with the adoption, thank you.

The condenser does not dissipate heat well, unclogging the air conditioning system.

It is possible that the refrigerant is leaking, and the air conditioner filter has not been replaced for a long time.

It is recommended to clean the pipes and change the air filter.
