How do I find the hose that drains from the air conditioner in my car?

My car is leaking water under the dash from the passenger side. I think the hose that is supposed to drain the water may be clogged. Of course I am just guessing. However, I looked from the top of the engine and can not find where the hose is coming out to actually drain that water. My car is a Chrysler Sebring LX so I was hoping someone could help me locate it without taking it in for service. I would like to run something up inside the hose and see if its clogged. Could it be that i will have to crawl up under the car to find the opening of the hose??
