The ac drain location on the 2022 Edge is located underneath the vehicle, hidden on the center tunnel wall just behind the engine and exhaust heat shield, near the driver's side footwell area.
Ford claims that the reason the hid it, was to protect it from road debris.
It sits over high the transmission tunnel hump, where the exhaust downpipe drops from the engine, and is completely covered by the silvery fiberglass exhaust heat shield.
To reach it, lift the vehicle, locate the transmission tunnel, and gently pull back or unfasten the corner of the heat shield fabric right next to the driver-side floorboard area. The drain presents as a small white plastic nipple protruding slightly from the firewall.
After you unblock the clog, I recommend using an evap cleaner to kill the mold that may still be lingering in the case.
