I have a 99 Passat and water has been leaking inside, mainly on the floor of the passenger side, but also on the drivers side. I am pretty sure it is happening with the AC. It has been really hunid here and the AC has been blowing out fog when its turned on cold. It seems to leak while the AC is on and then when I turn it off is when a larger pool of water forms. I read that some drain holes could be clogged or drain hoses cracked, etc. Is there anywhere that I can look to find out where the location of these drain holes, hoses, etc. are that I need to check? Thanks!!
