How do I unclog and AC drain hose that's leaking in the interior of the car? on 2002 Nissan Maxima

Whenever the AC is on for an extended time the water drains into the interior

You have to try to get to the hose. You might be able to locate it under the dash or under the car. It will look like just a hose hanging not hooked to anything around the firewall area.
