Steven,
Your AC drain problem is a known problem with Jeep Cherokee's. To repair the problem, it will take repeated checking your front right floor carpet often as you use your AC.
Yes the drain runs through the unibody frame and drains right under the RF floorboard. To fix the problem you must drill a small hole (3/8 will do) into the bottom of the Heater AC plenium. The spot to drill is under the right side dash, right under the glove compartment where the cowl meets the floorboard. If there is a cover under your dash, remove that and pull the carpet edge back away from the cowl. You will see the bottom of the plenium there. It's Black hard plastic It will narrow down into about 2 inches wide at the bottom. Locate the center of that and go up about 1 1 2 inches to drill the hole. You only have to drill through the outer layer of plastic. Water may come out of the hole at that time. Use a hard peice of mechanics wire or a coat hanger, I streched a coat hanger out to where it has the hook on one end and the rounded loop on the other. Squeeze it together so it will fit the drilled hole. Basicly you are going to snake the drain out and try to push whatever dirt of debris further into the drain so it will flush out. Then use an air compressor to blow through that hole also. You may have to do it a number of times until it gets cleaned out. After that put plumber's putty over the hole, it will stay plyible enough to take off and reuse. Then run your AC and watch under the Jeep on the RF FloorBoard to see it drain. Once it does, Great, BUT keep an eye on your RF Carpet to see if it happens again. I have to clean mine 2 or 3 times a year to keep it clean. Good Luck.
