AC Drain '92 525 wagon

[jcos16]

I have been told that above the tranny there is a squirrel drain that has a tendency of getting clogged. Insects like to get in there and clog it up.
I had ants in the car, then I started smelling a musky smell. Then I noticed the rug was damp.
Just a few months ago I changed the AC Air micro filter and the quality of the cabin air improved immediately. So it's not that.
Any input on this would be appreciated.

there are two drains, one on each side of the tranny, i've yet to see one clog but it's possible, also the one on the right side catches hell when the ac expansion valve leaks and the oil starts turning the rubber coupler on the bottom of the case to goo
