Heater Core Problem

My 99 WJ limited has recently started to smell like antifreeze when the heat is turned on. The windshield fogs up a little and then clears up and the antifreeze smell goes away after a couple of minutes. I'm pretty sure its the heater core. Does anyone know where to find a good write up on how to change it? I know its going to be a pain, but I have more time than money.

Pretty much the same procedure as replacing blend doors - remove the dash, completely! I've been led to believe that one should replace the evaporator core while you're in there, as they are flakey, too. I'd consider replacing the blend doors with aftermarket system if I had to pull the dash, as well.
