hot aircon

Yesterday we were driving out of town, middle of the day, with Aircon, when suddenly the aircon was not blowing cold air. Everything went hot. (Our aircondition here does not have the setting for Hot or Cold)

I went on to have this check on a auto aircon specialist, and he told me that something is not running and I need to replace it. (sorry i didnt hear what he said) however, he said that the Freon was still full and a crank needs to be replaced.

I went to have a second opinion on an employee of toyota service center for aircon (he's doing this outside of work for additional income), he said that once that the car is no longer blowing cold air, then the evaporator needs to be replaced.

Sorry to say this but I just don't believe other people saying that I need to replace something that is still working. Everybody would agree if I say that nobody wants to be fooled out of something.

now do you guys have any suggestions? any comments? anything to share about your experiences with our Yaris/Vios Aircon?

It could be caused by quite a few things:

1. Compressor or compressor clutch bad
2. Refrigerant pressure sensor bad
3. AC ECU bad
4. Evaporator bad (usually that one is not a sudden working to not working failure though)
5. Blown fuse
