You should be able to find several good threads on this forum, with pictures, that show you where the a/c drain is located, tightly jammed in next to the firewall behind the a/c unit. You can substitute almost any kind of tubing so that the condensation drains out rather than floods your floorboards.

Once you get the drain fixed, pull all of the floor carpets and make sure the floors are bone dry before you put it back together, so you don't end up with smelly carpet and rust problems later on.

I didn't remove the carpet from the console -- maybe that would have made the job easier?
