Answers :

Hello Mike.
Your heater core is leaking coolant. It comes out of the evaporator drain because the heater core is also inside your HVAC system case. Many vehicles are designed in this manner to help prevent a mess inside.
These are not the easiest vehicles to change a heater core on. Book time on Alldata for someone experienced is 6 hours to complete.
Stop leak additives are not a reliable solution and often can create a problem rather than solve one.
Hope I helped you along with this.
