You need to have the system checked to make sure it is not low on refrigerant. Due to the computer controls on that system it is difficult to diagnose based only on symptoms, but one possibility is that it has a low leak and is getting low on refrigerant which can make it intermittently blow hot. And the blower motor will stay on high trying to reach the desired temp.
