So I've done the research, looks like most people who have heater core issues have a damp passenger side floor. I do not whatsoever. The interesting thing is that when the heat is on, regardless on whether or not it's on recirc or the fresh air setting, it smells like coolant, but it's much much less so when I turn on the fresh air setting, I don't know where the recirc draws from whether it's from the bay or from outside the idk, when I turn the blower onto cold (without the AC on) the smell still comes through but much less than when the heat is on. Again, no leaks in the passenger compartment that I can see. The car is down a tiny bit on coolant, but not by very much. I'm assuming this is either a very small heater core leak or a small coolant leak in the engine bay that is getting drawn in by the system. Any suggestions.
