sunroof passenger side drain hose drains where

What is your question?

sunroof drains on floorboard on passenger side instead of where it should, where does the line drain?? We took off dash and side panels but can not find end of drain hose but see it in the side part by door. Need to know where it should drain to to find other end to clear. We can hear water run down the door jam so it has to be connected at the top. Just need to know where it runs to drain at bottom, we can't see it.

What makes this problem better or worse?

leaks only one passenger side. we thought it was the heater core at first until we poured water and watched it drain next to heater core to floor

How long has your 2005 Chevrolet Suburban 1500 had this problem?
