Check your drain tube - probably plugged up. just look in the engine compartment on the passenger firewall and you'll see it sticking out. Can usually just stick a small screwdriver up in it and clean it out.

cool, what does this drain tube look like? im at work right now, could i use a pen to un-clog it?
also my AC is making a funny noise, it sounds like i have 42" tires.
I AM ALSO HAVING THE SAME PROBLEM. I FOLLOWED THE INSTRUCTIONS AND THE PROBLEM STILL EXISTS. I HAVE 96 GC AND I HAVE LOOKED ALL OVER IN THE ENGINE AND FIREWALL AND HAVE NOT LOCATED ANY DRAIN PLUG. THE MANUAL SHOWS A DRAIN PLUG BUT THERE ISN'T ANY FOR MY GC. DO ALL 96 GC HAVE DRAIN PLUG ON THE FIREWALL ?
i cant find mine either, is it possible that when the dealer steam cleaned the carpets, water got stuck under the mats? i turned on the AC full blast and ripped up the carpets to see where the leak is coming from. when i did lift up the carpet, water just drips from the carpet itself, but not from any source above that. i tried the tube that blows the cold air to the back seat, but no water found. i dried up all the water (well most) and im gonna drive all day with teh AC on and lift up the carpet again to see if theres anymore water. i really hope its just water from the cleaning.
The evaporator drain plug drains into the frame of the vehicle. That is why you cannot see it sticking through the firewall. Jeep issued a Technical Service Bulliten a few years ago to help remedy the problem of a clogged drain tube. Here it is:
