Could be coming out of your a/c overflow elbow on the firewall. I believe the a/c / heater housing is sealed to keep the condensation from the a/c from leaking inside the car, so the heater side would be sealed also and drain thru the firewall.
I'd say it's a good possibility if steam is coming out of the heater. Just a thought.
