Drippy AC

["Mike Griese" <mike.griese@xxxx>]

With all the heat and humidity in the upper midwest, 
my AC has really been getting a workout. I noticed
that the carpeting was damp on the passenger side of
the interior. The drain hose for the evaporator casing
was restricted. A few seconds with the shopvac seems to 
have cleared the restriction and about 2 cups of water, 
however I am still getting a damp floor. Now it appears 
that the moisture is coming from the outside of the 
evaporator casing. I was working on the car with the 
doors open and the AC running in a very hot and humid 
garage. Is it possible that the condensation on the 
evaporator casing won't be a problem with the doors 
closed? If not, has anyone had any experience insulating 
the casing?
