I'm guessing a drain is clogged somewhere although I don't see any water anywhere and the inside of the windows doesn't fog up.

I'm planning on running a coat hanger through the drains once I find them all, maybe blow them out with compressed air.

Does it sound like I'm heading in the right direction?
