I have the same issue. Just the other day my A/C was blowing hot air. I have not changed anything yet. I want to drop it off to the dealer and see what they say. Another day it was back blowing cold air for a while then it was like it was winter over again, hot air. This will be the 3 thing that has gone on my car in about 8 weeks. I had 2 front calipers go in about 3 weeks apart. I just turned 64k. I would expect these thing with higher mileage. I had a f150 before the fusion and nothing went on that truck. No caliper, no a/c issue.
