How to locate the evaporator drain line?

I have a 2009 Ford Edge and the evaporator drain line is clogged. How can I locate the drain line on order to try to unclog it? There's so much water trapped in there that I can hear the blower motor squeal when I apply the brakes. I need to get this drained out before the blower motor is damaged. SINCERE Thanks FOR All SERIOUS REPLIES!

The evaporator drain hose is in front of the center console at the bottom. If you pull back the carpet just to the right of the accelerator pedal, you'll see a white fitting pressed into the driveshaft tunnel with the hose connected. The hose runs to the bottom of the evaporator housing. From under the car, the outlet is hidden by a heat shield for the catalytic converter. Bend back the right front corner of the shield to access the drain.
