My 95 Legacy Brighton wagon did something funny to me today. I got in it at 3:45, started it up and moved it about 1/8 mile to the side door of the building I work in to load somestuff into it. I got tied up and it sat for about 25 minutes idling with the AC on. I loaded up the car and left. As I got in I noticed it wasn't blowing cold air, and I could tell that the compressor clutch wasn't engaged, nor was it in high idle mode. About 15 minutes later, after driving on a highway at 70mph, all of the sudden the compressor engaged (I could tell by the squeel of the belt) and I had cold air. Rest of the way home (45 minutes) it worked just fine. Now, I just had the AC professionally serviced last friday and there were no leaks, and the system was fully chared. (This was because at the end of last year my condesor sprung a leak) So what in the world happened? Is there a sensor somewhere that could tell my condensor was roasting from sitting at idle for 25 minutes?

It's possible the engine temp or refrigerent temp got too high, and the ECU kicked it off.
