Volvo Repair: 1996 volvo 850 water from AC, air vent, volvo 850

Question
My air vent in making a water noise. I removed it and I found a lot of water in the case. I think it's condensed water from the AC. In fact the car doesn't dripping in the ground after a long trip with the AC on. However, I can´t find the AC drain hose to clean it if this is the problem. Where is it? Is it easy to clean, I mean, can I do it myself?
Thanks a lot and greetings from Spain.

Answer
Paco, yes, it is easy to clean.  Remove the lower panel from the passenger side under the glove box.  Where your left foot would rest, pull the carpet back.  There is a black panel that comes off.  You can now see the drain coming down from the case.  Pull it off and see how much junk is in there.  Problem solved.  Roger
