I'm having the same problem with the same model. The heater was working fine until I had a new radiator installed recently. I've been told that crud from the old radiator has probably clogged the heater core. From the engine, remove the hoses going into the fire wall. Turn your ignigtion on but do not crank. Turn the heater to on. Take a garden hose, preferably the cone shaped, twist action kind, and put the tip in the end of one heater hose and turn on the water but not too high because too much pressure could blow a hole in the heater core. The water should break up the debris. Repeat through the other hose.

I also have a 2000 jeep wrangler. This year has a problem with the heater core plugging up. You can either try to flush it out, or just replace the heater core.

the heatercore is most likely plugged up; get a new one; they are about 50 bucks; the ducts could have fallen off or rotted away but it think your heater core is plugged; a flush MIGHT help but a flush after your new heater core is installed would be money better spent
