I drive a 2007 accord LX. Today I was using my ac, no problem. It was raining and a little chilly, so I turned on my defrost (first time in a long time) and turned the air to warm. After defrosting my windows, I went to turn it back to cool and just use the vent, but the air remained hot. No matter what I did, turned on the max ac, circulated air, outside air, everything, it just blew hot air. Is there something stuck open that I can fix easily? Thank you in advance!

Thank you PAhonda! I don't know what happened, but when I went out to do the diag this morning, the ac is blowing again. I knew I should have just tried turning the engine off and restarting.
