I registered here just to say THANK YOU to a couple of you guys. I've been chasing this problem for months and have replaced everything from the temp control panel (all the knobs), the heater core, countless flushes, thermo's, literally everything on the system (albiet, the heater core _was_ leaking and needed replaced anyway).
I've spent months on this, and in the mean time my wife took MY cherokee and stuck me with the cold TJ.
I can't say thanks enough to this thread, and specifically the replies by 98tj25l and huntersemt10.
