No Drain Tube. Drains through the frame rail hole below the vehicle. My Jeep does the same thing. Pull passenger side carpet back. Drill a 1/4' hole in the center of the black evap housing. Wiggle a long wire through there then blow compressed air in the hole. This should unclogg it. Do a search on this, its a common jeep problem

Search where???
My haynes manual says that to remove the evaporator one of the steps is to disconnect the drain line, it you are to disconect it should it not be somewhere undert there?/

Where in the frame rail is the water supposed to drain out??

Use the search function here. Look under the vehicle around the passenger seat area u will see a hole, but u cant tackle the problem from there.

You gotta help me here I do l know what heading to search under on this forum, I keep getting a message that says my query is too short.

Where exactly do I do I drill this hole you mentioned and why must I wiggle a wire around in it?

At the bottom of the evaporator black case is a little plastic extrusion sticking down that appears to go thru the firewall but on the engine side it is behind the electrical box and is not reachable. It that the drain????

I took the advice of drilling a small hole in the evaporator drain housing, accessed thru the passenger side firewall under the carpet at the bottom of the "V" inside the round circle, immediately received a large backflush of water, inserted a wire and blew some compressed air into it and plugged it. Works great now.

I had the same prob a couple weeks ago - water running into rear right passenger floor thru rear vent. I ended up removing glove compartment on the '95 JGC, cig lighter, and faux wood cover over the radio/controls. Then blew compressed air into both ends of the approx 1/2 " diam rubber hose located on left side of passenger compartment - it connects to evaporator. Blew air repeatedly into those hose ends, pulled down passenger side compartment carpet/pad to reveal bottom of evaporator where it enters firewall. There was already a 1/4" hole there, so I blew air into that (don't know if I blew that hole out or was already there). Anyway, all that blowin' worked. Then went to Home Depot and bought some PC-7 epoxy paste, mixed up a little from both ends of the tube, smeared it over the hole, and next morning hole was sealed up (the stuff hardened like plastic). No leaking since!
