I have 1997 900S, the AC works properly most of the time. As a preface I must say that I've had perpetual problems w/ the AC since day one. Anyway, here's the scenario, I'm driving along w/ the AC on & cabin blower in pos. 1, 2, or 3, or 4. I will notice a constrictiion and a whirling noise (like putting a piece of cardboard n front of a fan), the airflow comming out of the vents is now almost nil. I then turn the AC compressor off, and wait 30-60 secounds. Like magic the constriction goes away, I turn the AC back on, until it happens again. Typicaly a few minutes later. Same process seems to revive it. This behavior tends to occur after highway driving for more than 45 minutes. What do you folks think, is there some sort of vacuum leak I can check? Is a solenoid closing prematurely? Are there other aspects ofthe motor that might influeence behavior like this, any possiblity that a vacuum line might be mis-routed. Any advice is welcome. Thanks in advance. Harry Guilford, CT
