All kidding aside, take it to camperworld or an RV dealer who is an authorized dealer for that brand of A/C unit and have them open the unit up, see if the water drains on the evaporator catch basin are plugged and have them properly clean the evaporator and other parts with a bleach solution. IF you run it and it has mold or bacterial growing on the evaporator, it can cause some serious health problems, especially in a closed environment like a sleeper.
Don't try to clean it yourself or spray anything into it.
