If the air conditioner in the car does not turn on, then you should not panic, since there are not so many reasons for this phenomenon in fact. View here for more info: air conditioning compressor not engaging
Surfing the vastness of the Internet, by the will of fate,you come across auto sites with tips for motorists. You read the advice and you start to wonder - either I missed something in this life, or skis do not go ...
For example, for the search query "The air conditioner in the car does not turn on", the lion's share of sites offered me a long list of all kinds of problems and solutions. Moreover, the advice is simply"miraculous" - you need to clean the radiator of the air conditioner,and if this does not help, then you need to check whether the engine is running, since when the engine is not running, the air conditioner does not turn on. Now I know why my air conditioner won't turn on. I just forgot to start the engine, and if it hadn't been for the Internet and found this valuable advice there, then I would have been sitting in my car in a desperate position.
No, I understand, of course, that 99% of the owners of such sites do not write articles themselves, but entrust this business to copywriters, thanks to their several cents per thousand characters of written text. Copywriters, as a rule, do not understand at all what they are writing about, so they simply rewrite and copy-paste articles with valuable advice from each other. Because of this, the Internet is called a cesspool.
And, in general, I'm already tired of fighting this myself.I didn't have time to publish the article, but it is already hanging on several sites
Well, okay. Let's go further. I also decided to create my own huge list of reasons - why the air conditioner in the car does not turn on.
Here are, in fact, all the items on this list:
1. The button for turning on the air conditioner does not work or the wires from the compressor fell off
2. Not enough refrigerant in the system
3. Everything. The list is over.
This is with regard to the question - "the air conditioner in the car does not turn on", and not "the air conditioner weakly cools." These are completely different topics and completely different reasons.
Reasons why the air conditioner does not turn on in the car
Now let's take a closer look at these two points.
Every car has its own electrical weaknesses, which over time start to cause problems. For example, a Chevrolet Lacetti has a disgusting soldering of the air conditioning control unit and sometimes falling wires from the compressor. This was stated here:
· Air conditioner does not work
· Air conditioner buttons
Using the air conditioner start button, we do not turn on the air conditioner directly, like a conventional switch, but give a request to the engine control unit (ECU) to turn on the air conditioner. If the button and its circuit have problems, then the control unit, of course, will not even guess about your plans.
Checking the button (say, with a multi meter) and the electrical connectors on the compressor is, unfortunately, all that you can do yourself. Since, if the circuit is working properly and the ECU received a request to turn on the air conditioner, this does not mean at all that it will satisfy your request.
