1998 Limited - Damp Floorboard

[heathtd]

Hopped in the car this morning and both drivers and passenger side floorboards were wet. Any ideas?

Things worth noting:

1) Strangely the AC drip was inside the cab, I moved it outside the cab and have not run the AC in 3 days. After doing this, I ran a box fan overnight on both driver and passenger side floorboards and confirmed they were dry.
2) Car sat outside overnight, no rain, but there was dew on the car this morning

I'm wondering if anyone else has encountered this issue. I've eliminated the possibility of it being the AC since it hasn't run in 3-4 days. Could it be a windshield seal or something?

Any help or ideas on what to check next is greatly appreciated.

Heater core?

this happened on mine, there was a plug taken out of the firewall that the previous owner ran some wires through,

Thanks, I'll double check the firewall...

A friend thinks the remainingm moisture in the floorboard is the cause. Awaiting the verdict tomorrow am to see how crazy I go on the hunt for the culprit.
