    You'd probably get more answers if more people could tell what you really are trying to find out.

    You said "AC condenser drain". There isn't one. The stuff inside an AC condenser shifts between liquid and gas phase, but it is in gas form when released. It doesn't 'drain', it gets sucked out and reclaimed through the gray-capped AC service ports under the hood.

    The AC evaporator is inside the cabin, under the dash, and it gets cold when it works, so water from the air ends up dripping off of it. That water drains out through a hose that you should be able to find poking down through the floor pan, near the base of the firewall.
