Having an air conditioner problem, especially in summer, can be a small but very constraining detail. In the city centre, you willingly open the windows of your Lexus IS to let in air, but once you get on fast roads, it soon becomes complicated.
It can sometimes blow hot air although you asked it cold air, or it could work intermittently.
You might not wish to pay repair costs without knowing if you could do it by yourself to repair your Lexus IS.
The goal of this article is to help you detect these possible problems in order to solve them as promptly as possible.
First, we will try to aim for the symptoms you figure out on the air conditioning failure of your Lexus IS.
Different symptoms on your Lexus IS air conditioner
You realize that it is not any longer effective, for example:
It works initially to finally only give back moisture and run out very very fast, or it works but with a particularly long time to cool effectively. Or also simpler, it simply does not cool down anymore.
First thing to think about at that time on your Lexus IS, it is likely that the gas charge is too short. This may very well mean that there is a potential leak in the circuit. If this were the case, we strongly recommend you to request the advice of a specialist and not do this on your own, it carries great risks for your Lexus IS and more essentially your own health.
This factor is partly due to the wear and tear of time, but also to the quality of your air conditioning system. To put it plainly, if you have a top quality car, you are theoretically much less bothered with this type of problem.
Also check you keep the air conditioning in good state all year round.
What does that mean? Simply use it from time to time for short moments throughout the year, which allows to avoid a “rust” of the system on your Lexus IS. It consumes slightly more fuel, but as replacing your air conditioning system is much more costly, you profit in the long run.
Different problems on your Lexus IS air conditioner
Now let’s look at some of the problems you may face on your Lexus IS. Bear in mind that your air conditioner system is a very complicated system, made up of a multitude of parts that can potentially lead to failure.
First, as outlined above, you may have a gas leak and as a result no pressure in the system.
Also, it is therefore likely that your compressor is out of order. Same observation as above, it is no longer possible to compress the gas, as a result no more pressure in the system.
Attached to this compressor of your Lexus IS, a pulley allows for it to rotate. If this one were to stop working, a chain reaction would happen with the compressor stopping, and therefore as mentioned above, no gas compression, no pressure…
We realize here that everything is related and that each piece has a crucial importance, just like a chain work, a single lacking link and the whole chain is stopped.
Another delicate point, still on the theme of pressure, if by chance a too elevated pressure was felt in the circuit, a sensor will then be activated in order to stop the operation for basic safety. We can imagine here the work of a protection fuse on the electrical circuit of your Lexus IS.
Regarding the temperature sensor, there may also be a failure. Just imagine that it is no longer able to identify the temperature of the inside of your Lexus IS. As a result, it does not detect what to give the computer as information, which will lead to the air conditioning being switched off as a result of the lack of consistent data to be processed. Here again the air conditioning will have been turned off by the computer for safety reasons in order in order to avoid improbable situations, for example, where it is considered hot in your Lexus IS and sends cold when it is the opposite.
If you were to employ a professional, here is an notion of the prices you would have to pay:
Let’s imagine that you reload your air conditioning with gas, it varies from 40 to 60€.
If, on the other hand, you had to replace your compressor, it would cost about 350€ new, much less expensive second-hand, around 150€.
So here is a set of complications you might face on your Lexus IS, as you thought, in most cases it is better to call on an expert to avoid potentially major accidents. Remember that in the case of air conditioning, you deal with compressed gas that is dangerous if you are not careful.
