Wow, what a chore you are about to get envolved with! You must remove almost all of your dash including the center. Next you will need to start removing the vents and other parts of your AC system under your dash. Your heater core is inside the front part of the blower box. First you must disconnect the hoses inside the engine compartment on the passenger side where they enter the fire wall. After you remove the entire black heater unit from under the dash you will be able to see the core just below the flap. You must carefully separate the blower box into its two halves to remove the core. The hardest parts are getting the new core back throught the fire wall (I enlarged one of the holes) and making sure your cables from you ac control are adjusted correctly. Sorry this is not a very technical discription.
