I have read several sites and threads, but none match my issue close enough for me to feel comfortable to diagnose...
I have a 2011 Acadia that we bought used about 11 months ago. Last weekend, driving down the road, there was a noticeable hissing sound from the dash that went on for about a minute or three. Shortly afterwards, the a/c stopped blowing cold or even cool air out of the vents, only warm air (both DR & PS side). It has since blown cold air once or twice, but now it is blowing warm air only. It also occasionally makes the hissing noise. The Compressor is still cycling on and off, but no cool/cold air. I had a friend tell me that it could be the Blend Door actuator, I have read all about the ongoing issues with the Evaporator Core....
Please help if you can, I certainly do appreciate your assistance!!!
