Water on floorboard

I am fighting water on the passenger side floorboard. I am sure the evap drain tube is plugged because there is very little ouside underneath the car. I can not find the drain tube but I suspect it is behind one of the heat shields on the fire wall. How do you unplugg it??

Thanks

My Dad's 94 Ram 2500 has the same problem. We have never been able to find out how to fix it. Good Luck!
