The fan is behind the dashboard, and not easily visible. This sounds like the fan motor or the blower motor resistor may have failed, and the vapor you saw may have been smoke from one of those items. I would get it checked out very soon if it was indeed smoke, that can turn into something worse.

Second thing may be a water leak, either windshield or heater core, rusted the fan and the vapor is water vapor from sitting water.
