Hey Bo== It should be under the hood, against the firewall on the passanger side at the botttom of the evaporator case.Be careful unstopping it as the evaporator is just above the case and can be punctured. GoodluckJoe I dont know about the '96 but I just spent a couple of days cleaning and Surfing the net to determine the best options availiable. As it turns out the 1998 Jeep Grand Cherokee A/C drain dumps into the frame rail. If you look up under the frame rail the discharge is coming (or supposed to) out of the first large (1/2 x 1) slotted hole. I was lucky and only had to flush that area out with the hose and it fixed my problem - so far. From what I have read in the last couple of days it could have been a whole lot worse. If the cleaning poking and prodding hadnt worked I was going to drill the 1/4 inch hole in the cab side duct (vertical face of the circular area just above your feet and approx in the middle of the duict. - the drain is supposed to go away and down from this location and into the frame rail) and use a coat hanger to see if I could feel a blockage. If that didnt work- God Forbid - it was going to have to be the disassembly of the interior to remove the A/C assembly. From what I read it a 6-18 hour job depending on your luck. Some posters even suggest that that is a good time to buy another truck. I think I may have givin that some serious consideration had it come that far. Thanks to all the posters on this site and the rest of you too posting the net. Sorta makes you wonder what we did before it. Good day and good luck. Don't know about a 96 but on my 95 it is under the dash on passenger side floorboard. You have to pull up the carpet and padding, on the vertical rise part of the floor board you will see a plug in the middle of a small black cylinder part of the duct work that comes through a circular cut out in the floorboard. Pull that plug out and get a long wire and run it in the hole, several times. The drain hole runs into the frame rail of the Jeep, you can't reach it from the bottom. You will have to seal the plug, get a new one, or make one(I cut off a section of a pencil and epoxied it) to reseal the duct work. I drilled two holes in the floor board to make sure it stays dry because it still condensates some on the duct work, it gets a little bit of condensation on the floorboard still but the carpet and padding stays dry. http://home.sc.rr.com/janet/TSB/24-06-96.htm Look on the pass side of the car against the firewall and there should be a hole or indentation in the evaporator case, Be careful cleaning it out as the evaporator is about 1 inch above this case and can be damaged with a sharp instrument.
