2020 CRV, my AC usually works fine. With AC on, setting temp to 15.5, 16 etc. I get cold air.

Sometimes if I turn the AC off, then turn it back on, it starts to blow hot air unless I put it at LOW setting. Even setting at 15.5 it blows hot air. This happened several times now. I don't even remember how it resolved itself the last time. Is there a malfunction somewhere. The auto button is always off.
