Mercedes Benz repair: Water on floor 85 Mercedes 300D, drain hoses, climate control

Question
Just purchased last September.  When I run the AC, driver's side floor gets wet.  This happens when there is no rain, so I believe the problem to be in the AC draining set-up.  No one has been able to tell me where the drain hoses for the evaporator are, and I have had no luck finding where they drain under the car, and don't know where they are connected inside the car.  Have searched the web for pictures or other help, to no avail.  Can you tell me how to get to the drain hoses?  What else should I be looking for?  

Answer
The drain is above the center of your transmission = impossible to reach.
The dash must be removed to remove the heater-A/C case to access the drain hose.
