Angry Heater Core???

So, can anyone tell me the difficulty level of replacing a heater core in a 99 Jeep Wrangler TJ? If you have the major steps that would be appreciated also!

AFAIK, the dash needs removed.
Don't have access to my FSM right now, or I'd tell ya what it says.

I can't remember the full procedure...run a search, I linked to a how-to on this a while back.

You will need to remove the dash which is a pain in the ass, and you'll also have to have your a/c system discharged because you'll have to unhook a couple lines. Once it's done, you'll need to have it recharged as well. You also should replace the dryer in the system...and I think something else but can't remember...they're cheap and they should be replaced anytime you have the system open.
