Hi, have a 2002 Stilo Abarth that aircon has stopped working. This seemed to happen over a period of a couple of months I think. Obviously suspected it just needed regassing. However, this has been checked and there is plenty of gas. The actual system seems to be working in that clutch is engaging, fan comes on but there is virtually no cooling. The mechanics who checked it seemed to think it was a TX valve which I gather is the expansion valve. I'll probably need an aircon specialist to explore further but curious to know if anyone else has had a similar fault and if this seems a possibility? I was told that the valve is located behind engine in front of firewall so difficult to access.
