I have looked everywhere for the location of the drainage tube for the AC condensation. Does anyone have a clue? 2004 Endeavor

 

I found it. It is at the dealership. Seems that engineering stuffed it totally inside the heater unit under the dash. The only way to get to it is to take the inside apart and unclog the tiny hole. And by the way, They now have a little filter kit you can have installed to prevent this from happening again.. $490.00 later, my Endeaver does not leak in the front passenger floor.
