It is a major undertaking to replace the front heater core, or the AC evaperator. They are both housed inside a plastic chamber behind the dash. You have to remove the left side of the dash, and all associated wiring, lower the steering column, and open the AC system in order to get the Heater/AC chamber our to remove the top of the chamber and lift out the heater core. The Haynes manual gives a step-by-step directions. It took me most of the day to replace my AC evaporator. Good luck, and don't forget to connect back up all the electrical plugs.
