Duo Therm AC 620215.303 not draining water to the outside

I can see my drain lines from down below. I took them apart and blew them out with my compressor. Went on top and did the best I could because I can’t see where the drain holes are in the pan. When I disconnect drain hose in the bottom it seems to drain fine to that point. I blew out the down side tube and found nothing wet under the coach but it seems to not be draining there
