If that's a 4" long rubber hose you're seeing, that's coolant leaking due to a leaking heater core. You can verify that by adding a small bottle of dark purple dye to the coolant, then searching a day later with a black light. The dye will show up as a bright yellow stain.

Auto parts stores will have the correct dye, and those that rent or borrow tools should have a black light.
