AC BLOWING HOT AIR on 2006 Mercedes-Benz C230

I've noticed some hot air coming from the vents and some cooling air as well. But today it just blows hot air... I'm desperate... I live in So. Florida...

You have to close the vent, there open, turn on the ac and then turn it off again that will do it.
