AC Problem ! Leaking !

Thanks guy's. Further inspection shows water coming in from one of the four screw holes which holds the inside AC facing/cover. Also water is running well across the outside roof but draining the opposite way to the back. So the thought of something lodging and preventing normal flow may be on the money.

My unit has no ladder and not sure i can get my truck in tight enough to get on it's roof to make it to the trailers roof, but will try. If not will have to put up with a drip when AC is off for another two weeks. Funny how it has been fine until now.

Thanks again !
