It has to come out from the inside...
i believe on your year, that the right and center dash need to be removed then just dig in...
this might help...

Big hint: Before you reinstall the heater box assy, spend 20 bux on a reseal kit for it. I put all new foam seals in my whole A/C system and now, it blows about twice the amount of air it did previously.
In fact, I had already installed a new compressor, hoses, POA valve, and evaporator core just before pulling the dash. The A/C blew cold but never enough air. Now that I have resealed the vents and such, the system never needs to stay on HIGH for long.
As for the heater core, you need to get the whole box out of the dash. You'll find it buried in there and tricky to get out. Don't damage your evaporator core with the heater connections as you pull it.

you need to remove the right side lower dash, the center dash bezel then remove the cover. The hoses connect under the car. It took me about 3 hours...and I was not rushing to get it done. Just take your time and don't force anything
