Coolant leak

I own a 1995 S600 coupe. Every 2-3 days the low coolant light has come on and I have had to add coolant. I looked underneath the car and found that coolant was leaking from some type of overflow hose that is located beneath the passenger compartment of the car. Does anyone know where this hose goes to?

I only suspect your heater core may be leaking into the AC plenum and that is where the drain hose is
