So this weekend I looked into this a bit more and can confirm that coolant is coming from the A/C drain line. I found paperwork where a new heater core was installed in 2018. Curious if a bad thermostat or anything else would make this happen? If it truly is a bad heater core can I just do a bypass for now and fix it this fall when I'll need heat? (I'm in south Alabama so I won't need the heat until mid November) Any negatives for this for a few months.
