specially on long trips, it travels more comfortably in a cool car, for example on the way to summer vacation. Every now and then it happens, however, that the air conditioning does not cool properly. Why is my car air conditioner not blowing cold air is the main question here and I’ll try to answer this question in this article.
If the air conditioning in your car doesn’t seem to work, don’t worry. First, you should diagnose the exact problem.
If your car doesn’t seem to be blowing colder air, there are several things that could be causing it. When you have a better idea of what the problem might be, you will know what to expect when you bring it to your mechanic and you will have fewer surprises.
Why is My Car Air Conditioner Not Blowing Cold Air
Following are the most prevalent reasons for the above-mentioned problem of car AC about its coolness.
1- A split can damage the capacitor
If the air conditioner in the car does not cool, this can be due to a defective capacitor. It can be damaged by Stone impact (spreading material in Winter) or wear and tear to such an extent that small holes are formed in the Material. In this case, the damaged part must be replaced. It is best to do this in a specialist workshop.
2- Some Refrigerant always Loses Air Conditioners
Small quantities escape through the seals of the system, as they harden over time. However, if the refrigerant level is too low, only warm air is released from the fan. An intact air conditioning system cools the air noticeably immediately after switching on. The refrigerant can only be refilled by the workshop.
3- Infrequent Use
The compressor liquefies the gaseous refrigerant with high pressure. Its moving parts can become stuck if they are not lubricated. To do this, the compressor must run regularly. If the air conditioner has been turned on only rarely or not at all, the compressor could have suffered as a result. Repair useless, an exchange costs 1000 Euros and more.
4- Leaf Residues and Other Dirt in the Radiator
you can affect the function of the air conditioning. If the radiator is clogged, too little or no air will enter the air conditioning system to cool the interior of the vehicle to a comfortable temperature on hot days. Therefore, clean the radiator from dirt!
5- Irreparable Damage: The Compressor has Suffered
However, the compressor may also be defective. It consists of moving parts, which convert the actually gaseous refrigerant into liquid – only so the car can be cooled. However, the parts remain movable only when the air conditioner is switched on regularly. Once fixed, the compressor usually cannot be repaired and must be replaced. Tip: switch on the system every now and then, even in Winter – the best measure against fogged discs!
6- Weak Air Conditioning Typical for Older Vehicles
If you own an older car, this could be the reason that your air conditioning no longer cools. Older cars often lose coolant over the seals of the vehicle. The reason: the SEALs gradually harden and therefore no longer function well.
If you notice that the air conditioner does not cool down the interior properly, you should have it checked in a workshop to make sure that the coolant needs to be refilled. By the way, each car over time loses small amounts of coolant.
If you have your car air conditioning system serviced, not only is it checked whether all lines are leak-proof, but a complete Check-up carried out. In order to prevent consequential damage, an important point here is the cleaning of the ventilation and heating system. This is disinfected with a special cleaner. It ensures that neither mushrooms nor mold settle in the plant and secretes an unpleasant smell. The pressure is also checked and missing coolant is replaced.
In most cases, the air conditioning is also serviced as part of the annual inspection. If you do not have annual maintenance, you should replace the interior filter every 15,000 kilometers. Experts recommend that no more than two years pass between two maintenance operations. Because from year to year the plant loses coolant, which can lead to permanent damage to the compressor. Consequential damages such as this can quickly cost 1,000 euros or more.
Most problems with your air conditioning system need to be addressed by a qualified certified mechanic. According to your knowledge of cars, you can do certain things yourself, to avoid repair. For example, you may be able to recharge your coolant or check for Freon leakage. However, if you have already tried adding refrigerant and your air conditioning system is still not working, it may be time to call in an expert.
I hope, these are the main reasons of your car air conditioner not blowing cold air. If you observe any other reason please do comment in the comment section.
