I just recently got a 95 850 Turbo. Everything is running fine except the AC, sometimes.

When it is really hot outside (Above 90) and Im running the AC, the cold air will stop blowing after about 5 minutes, and will just blow warm air. Then if i turn the AC off for about 1 minute, and turn it back on, cold air will come back out. I have read on another forum that someone with a V70 was having similar problems. He found out that his compressor clutch magnetic coil was overheating and cutting out. I do not know yet if the Evaporator has been replaced on this, but i intend to find out soon.

What makes me think its the same thing, is when its not so hot outside (in the 80s) the AC will blow non stop, and MUCH colder than when its hot out. It will never cut out.

Another thing ive noticed is that when i drive on trips (over 2 hours) with the AC on, a mist, or water vapor will come out of the vents. But it has yet to do it in the city.

So does it sound like the Compressor clutch coil? or maybe something else? Any help is appreciated. Thanks
