Could be that you need some welding done underneath, but could also be the heater matrix. On most cars, that little box of tricks is buried away in the dashboard which needs complete dismantling to reach the blessed thing!
If the water spells like antifrreze, then the heater core may be leaking. If it is just plain water, the drain for the air conditioning is plugged up. There is a hose that you can reach from underneath the car that is right under the heater-a/c unit and the hose can be cleaned out with a short piece of wire of even a straw.
