Interior AC duct loose + moisture in glovebox

[scoot]

Today I noticed that there was a significant amount of moisture inside of my glovebox when I noticed that my digital camera (with a metal body) was wet after sitting there for an hour or two! It scared the crap out of me but the camera seems to be ok; on the other hand I want to make sure this doesn't happen again.I noticed the duct that connects to the left passenger side air vent seems to be loose and blowing half of the air into the passenger cabin, and half into the glovebox area. The air outside was somewhat humid and the air blowing into the passenger cabin was as well; I don't remember if I was running A/C or just running the fan today. I can push the duct back in but it'll dislodge itself easily. I looked in the 03 Matrix manual but couldn't find anything; I figure I'm just looking in the wrong place. How would I go about trying to fix this (aside from duct taping it or something along those lines?)Also is there anything else that could have caused the moisture to leak into the glovebox? I'm guessing the air filter which I had not checked in quite a while until today could be a potential culprit (or not?)....let's not even talk about how dirty it was. Any advice would be appreciated....thanks
