Fiat Stilo Bizonal Climatizer

Estimated MDM friends, my question is: I have a 3P Fiat Stilo with Bizona air conditioner and it takes a time that comes out very little air flow, the antipolen filter changed for a new one but the problem persists, I do not know if it will be due to the switchboard or some relay that is failing. Any suggestion? Thank you very much in advance.

Czech first than the air is loaded, that of the air conditioning

I think it should be loaded, this would be the second summer since the last time I happened to him and last summer the same thing happened to him, so I have to think that the problem will not be in the lobby of the air conditioner.

You may have a escape in the system, it is the easiest and fastest, also when I spend last summer, then take off something or something something? Well luck and warn, the first step is what I told you before disarming anything.

Aver, if you put hot air, it comes out in quantity ?? And if you put the cold no?
