I noticed over the past few days that I've been leaking coolant from beneath the passenger door section. The drips in the parking lot are almost exactly where water from the condenser would fall. I lifted the car and found where the coolant is dripping from. There is a small hole into the floor pan. Coolant is dripping from here. I don't know how to diagnose this because I can't find the original source of the leak. I've been conditioned to call coolant leaks in this location a heater core problem, but I don't smell coolant in the car even with the heat on full blast.

Here is the leak. I'm not sure if this hole is meant to be a drain hole for the condenser water drippings, but it's functioning fine as a coolant drain hole

. I had to remove an undershield to expose this.

That last picture is just to show how far back this leak location is

What's going on here?
