95 Ford Contour, blower motor or heater core leak?

[House M.D.]

My 95 Contour has been leaking from beneath the glovebox for a week now (slight smell, has foamed up like mold and left black staining on the passenger's floor mat). This led me to think I was leaking antifreeze, although there was no burning antifreeze smell, just a slight odor. After removing the foam under the glovebox I've found that the leak is directly beneath the blower motor. I checked the cabin filter; it is brand new and clean (no clogs there). The only other thing I can think of is a clog in the box drain, which I can't locate. But can I be pooling water from my evaporator core is I never use the A/C? And would the fluid be leaking a foamy fluid and staining black what I assume is refrigerant? I do use heat and defrost on occasion; the A/C hasn't been touched in a year. The heater core itself is central behind the dash, and not where the leak is originating.

Any thoughts would be great. Thanks!

I still think its the heater core..if not that, then I think the windshild or sunroof is leaking

Actually sounds like a heater core leak, to me.
