Wet passenger floorboard

Now that duck season is over I was cleaning out the Burb. I removed the passenger side floormat and it was soaked with water. I have Catch All floor mats so even if wet boots were in the truck the mats would catch all of the moisture. It is not antifreeze judging by the lack of odor and color of the paper towel I used. I know there is a tendency for the HVAC drain to clog. Where is this drain and what is the best way to clean it out?

water in passengers side-

mine is caused by the seal around the fresh air inlet- i remove the cowl vent- hard to locate all the screws with out a mirror to look down at them-remove wipers- there is an access panel oval in shape that is "glued down" i pried in up and ran some silicone around the rectangular "stand pipe" i think there is a proper seal but appears that you would have to remove the dash to get to it!!!!!! mine is a 1995 chev silverado-not an easy task but that is where the water came in (a LOT of water) Hope someone posts on the proper way to stop the leak.
