OP, it is basically behind the glove box. You can remove it and a shroud/cover should be covering the heater core. Of course you'll drain coolant, disconnect hoses, etc. but it is not too bad. I would get a good AC Delco replacement so you aren't doing it again anytime soon.

Its maybe 2 hours at the MOST. Take the hoses off under from under the hood, remove the glove box and I believe another insulator panel or 2, and the heater case is right there.
