Just look for the rubber drains that go from the bottom of the AC unit to the floorboard. Chances are one or more is pulled out or broken. (There will be more than one if have the Auxiliary air conditioning system).

Also inspect the front drains in the cowl area to be sure they are open.

Hi -- do you have any basic images/diagrams of where the cowl drain is located as well as the AC drains from the AC unit to floorboard?

[wvicary]

Sorry I don't have that information at hand but will post it if I find something.

Please help having the same problem with my 06 Turbo s, the passenger side floor mat is soaking wet. Any diagrams to show where these drains are located. Do I have to pull anything apart or is it visible from under the dash?

Remove the trim under the glove box, (same procedure as for interior filter replacement) big part of the AC system should be accessible now and search for a rubber hose between the system and the firewall.

After removing the A/C cover I found one drain hose that was connected and passing through the firewall. It was in good shape and I did remove it and ran some water through it to make sure it was not clogged. Is there another possible source for the water on the passenger side? another drain hose?

You have tested the drain between the ventilation channels and fire wall, but have you checked the exit on the channels to the drain hose for blockage? If yes, take a look for standing water or cracks in the room under the wiper trim, use a garden water hose and test the front windshield seals and sun roof front drains as well. There must be a leak somewhere in the ventilation (AC) channels, windshield seals, roof drains or in the room under the wipers.
