Airconditioner not draining.
 

I'm experiancing water build up in the rear passenger floor board area of my 02 A6 Quattro. At first I thought it was from washing the car or when it rained. Since the car has not been washed or rained on recently and when the car is driven with the air on there is never any water under it when parked, I feel it is not draining properly. I've read the forum and checked the obvious places, I've run water in the drain areas and they seem to be working fine. I have not removed the battery as of yet. Could someone tell me where the airconditoner drain is located?


Thanks,

Perry
