Hey guys,

I've had my 190E since last October and the AC has never really worked properly since I got it. Today I tried to mess around with it a bit to see exactly why it's not blowing cold, well, at all! The compressor is new and so far I've been told that it's full of freon and that my evaporator might be bad. Thing is, after today I don't really know if that is the case.

I started her up, pressed the AC button and felt/saw the compressor kick in as well as the fans. Air started blowing sort of cold out of all the vents pretty instantly, but I wasn't moving so I didn't expect much. I turned it off, and took it for a short drive. I tried turning the air back on again and nothing, just blew outside air. Tried turning it on a few more times and still nothing, and it drove the same, so I came home. I came to a stop and turned the AC on again to see if the compressor was coming on at all, and it wasn't. No jump in RPM, nothing.

So I shut her down all the way, took the key out etc. and the fired her up again. Put the AC on a viola! The compressor kicks on! It starts blowing somewhat cold, so I take the chance and start driving around my complex. I came to a stop and turned it off and saw that it did, then turned it back on again. It looked like it tried to come on, then didn't.

I don't know what the problem is, but it looks and sounds like something is causing the compressor to shut off and then it resets itself when I shut the car off. Who knows, it might be my evaporator, but I'm not sure. The air isn't freezing by any means, and it's at its lowest setting, so I'm not sure if that is a sign of something or not either.

Any ideas? She's a 1988 2.3 8-valve if that helps at all. Thanks!
