Well, for starters, you should have posted this question here, http://www.jeepforum.com/forum/f9/
More on topic, when the engine is cool, pop the rad cap off and check the level. If its full, put the cap back on and start the engine. When it gets hot, see if the heater hoses on the firewall are hot. If one is significantly hotter than the other (with the heater on "hot" and fan on low) then you may have a plugged heater core. If both hoses are hot, then you may have an issue in the heater box with the blend door or its motor or the controls. I don't know the TJ's that well, but that should give you a place to start.
