I had a little condensation and some water in my passenger floorboard when the ac was on for extended periods. Did a little research and did the ol' weed eater string trick to the ac drain tube... WOW!!! I was NOT expecting that... I bet about a gallon of water drained out... (half of it on my face and chest before I slid out of the way)... It drained out for a solid minute once the gunk and slime washed out of the tube.
