yes your heater core is leaking into the condensation pan underneathe the dash and comming out of the tube on the wall, If you want to flush ,thats fine and then replace the heater core, but depending how big the crack is on the core, when you flush it it may leak inside the car, so maybe that would be taking too much of a risk, just replace it then flush so you dont cause any damage to your interior.
