My Truck is leaking water! on 2004 Mercury Mountaineer

why is water leaking in the middle of my vehicle especially when i turn on the AC, it comes down quickly

There is a drain for the A/C evaporator that is supposed to drain the water to the outside of the cabin. This drain hose needs to be checked, maybe it is disconnected or plugged.
