Like the domestic air conditioner, the car air conditioner works practically the same, so the breakdowns that cause it not to cool also tend to be very similar.
In this article, you can see why is my car air conditioner not blowing cold air. This time, we will proceed to explain the causes that cause the air conditioning in your car to not work.
Why is my car air conditioner not blowing cold air?
It is important that you look closely at this because it is not the same as a car with 1 year or less, it stops cooling the a / aa that it does when it is older, for example, 6 or 7 years.
This is important because the most common cause that is attributed to not cooling, in air conditioning, is always with the excuse that it lacks gas and, as you can see in this article, it is not always the case.
What’s more, I recommend that you always be suspicious when they tell you first thing that the air conditioning in your car is lacking gas.
As a general rule, air conditioning equipment should never lose the coolant (gas), since it is a closed and hermetic circuit. In the case of a gas shortage, it is essential to find the corresponding leak where you are escaping.
Another thing is, as I said at the beginning, that the vehicle is several years old, so it may be normal for a leak to occur due to wear of the components, but in a new car, this failure is less frequent.
Therefore, it is of utmost importance that you be clear that when there is a lack of gas it is because there is ALWAYS a leak in the refrigeration circuit.
Just as you clean the filters for your home air conditioner, you also need the one for your car for its correct operation. Therefore, it is important to know where this filter is located in order to clean it.
You can look in the book of characteristics of your car or contact the manufacturer to tell you where it is. If you cannot access or do not know, you should go to a garage or mechanic who can and can extract it for cleaning.
If the filter is dirty, it will cause alterations in the circuit pressures and this will in turn cause it not to cool as it should.
Belt break that moves the compressor
Like most mechanical components of the vehicle, the air conditioning motor (compressor) requires a mechanical force to move it, and this is achieved through the movement of the vehicle’s own motor. This is accomplished with a strap.
This belt is usually made of rubber or rubber, so after a certain time it can pass and break, causing the compressor to be unable to operate.
For repair it is as easy as going to a workshop and putting on a new belt so that the motor movement drives the compressor again.
Failure or breakage of the compressor itself
This type of failure usually occurs especially if the circuit runs out of gas, since it is in charge of cooling the compressor itself. If the circuit runs out of gas, the compressor will heat up and cause it to cold.
In this case, it will be necessary to replace the compressor and carry out the subsequent gas charge, although it is vitally important, in case it is due to a lack of gas, find the corresponding leak.
Failure in any of the fans
Like any air conditioning unit, a vehicle has 2 fans, one that moves the air inside the passenger compartment and another that expels the condensed hot air, which is always the vehicle’s own radiator fan.
If you look, all the cars that have a / a have another radiator next to the radiator that cools the engine. Normally, for the use of air conditioning, that fan will only turn on in case the vehicle is stationary, since when the vehicle is in motion it is the same air, caused by the movement, that cools that radiator (just as it does with the radiator that cools the engine).
So when we have the car’s a / c in operation and it is stopped, the radiator fan starts to work, which does not mean that the vehicle’s engine has warmed up.
The same can happen with the indoor fan. If you see that when you start the a / c it does not move, it means that something is wrong and you will have to go to the workshop to see what happens to it.
