I'm sorry but, this answer is hopelessly inadequate. This job, on this car, is quite complex and time consuming.
First be prepared to mark cables, connectors and etc so that you can see what they went to on re-assembly.
Also have a sytem to store and label the many different fasteners that will have to be removed.
I have a factory shop manual and found several areas in which no guidance was offered or where information was incomplete.
I wouldn't start this unless you are an above average mechanic and have good tools and better than average patience.
You have to remove the lower and front interior trim from both front doors.

Remove the winshield wipers and the trim beneath it. The nuts that hold the rear of the bracket in place are in this plenum area. The manual has arrows pointing to the defroster grate. You cannot reach the nuts from here and the grate will break if you try to pry it out.
Remove the dash support bracket. when you remove the fuse/relay/distribution panel (FDP) from the bracket you may have a very hard time getting this back together.
I had to take all plugs off the back of my FDP, of which there are about 20, and sort the whole mess out. I left the wires hanging from a temporary bracket on the metal area below the windshield until it was time to reassemble. I then put the dash support bracket in, clipped the FDP in pace and the plugged all the connectors into it.
Disconnect the heater hoses and ac hoses.
Remove the heater assembly. One of the bolts, that holds this in place, is hidden under the engine-side insulation directly below the bolt nearest the heater hoses. You will see a tab on the aluminum that you can pull away to reveal it.
Remove the heater core from the heater assembly
Reverse to reassemble.
As I said, label everything, including fasteners.
As you might have guessed, this is no afternoon project. I would set aside a MINIMUM of a couple weekends for this. and as I said before, don't start without a shop manual, good tools and an understanding partner.
