water dripping from underneath pass floor board

I have a 99 Sebring convertible and there is a slow drip from underneath
the passenger floor board, almost directly under the dashboard. It's like
air conditioner condensation drip but does it pretty much all the time.
Problem is it must be running over rusted metal wherever it's coming from and badly rust-staining the driveway. Don't know if water is collecting after washings/rain and slowly dripping or prob w/AC.
Any suggestions??
