First you pull the whole dash out! It has two bolts under the speaker grills, two other bolts on the side of the dash(one on each side), then two more bolts in the center area, right by the drivers right knee, and the other by the passengers left knee. Take the cluster out, and take the center HVAC/Radio console out. There are two screws in the center vent to release the top of that console, two on the bottom under the ash tray as well. Takes about an hour to hour and a half for all that. Then you will see the heater box and the heater core pipes. You have to remove the heater box fully to access the heater core. When all apart check all vacuum lines for cracks and the rubber connectors for cracks. Replace any cracker rubber connectors or vacuum lines while the dash is apart. I think I dedicated a whole thread here to doing it!
