I worked on the A/C tonight, 3 hours work including the 1 hour stay at
Home Depot, trying to find stuff. The leaking problem was (maybe) a broken
90 degree on the passenger side drain hose. I got the soft water 3/8"
pond/landscape hose from the lawn center. and ran new hose on both sides
of the van. I ran the hose through, the body ,drilled holes to run the
hoses straight to the ground , to keep water from buliding up in the body.
I heated the ends and slightly crimped them, so the water will not be
disturbed, by air flow.The worse part was dropping the unit halfway,on the
passenger side to do this .

I got a dremel tool and opened up the  supply/blower vents to have more
direct air flow.With air condtioning foil tape. I taped all the open areas
of the evap. section. I also closed the two small vent on the side of air
vents .On the back side of the air intake. I tape a section of air filter
medium/material to help keep the evaporator clean.

Then I installed a fan near near the driver's head to blow more to the
cab. Which can be turned around to blow on sleeping campers. The fan plugs
into the aux. battery.

I cannot thank everyone, who sent me intel on how to repair this turd of a
design....Once again thank you....
