check to see if there is a hole on the outside of the ac if there is make sure it is not clogged so any condensation can leak outside and not in. If there is no hole then take a drill and drill a small hole for the condenstation to drip threw
Hey,
Have you checked the tubing? I once had the problem with my RV that a tube was leaking wich caused it to blow hot air only. The liquids that where leaking caused severe damage aswell.
