More than likely it is an electrical problem. Look at fuse # 14
rotate or put a new one in there. That's the one that sends 12V
to the monovalve to keep it closed. When the fuse goes wonky the
monovalve gets no 12V and opens letting hot water through. The AC
works as normal but can't overcome the full hot flow of the
water. Happened to me just a few weeks ago.

Yeah, it was cooling just fine. She was driving along the road
when the vents started blowing hot air. The compressor is
clicking on and off while this is happening so I am thinking an
electrical glitch.
