The heater is located under the dash board to the right and down from the radio. To remove and replace it you will have to remove the dash board down to the fire wall. Also, you will have to disconnect two hoses that connect up to it from the engine compartment. These are located in the back of the engine and down on the firewall about midway. Once you remove the dash board and locate the heater core you will be able to see the location of these two hoses. Removing the heater core is time consuming but it will save you about 700 dollars.

under the dash on the pass side there is a large black plastic box. take out the 6 screws and pull off the cover. there is a wire attached to the top that controls a flap, that just lifts off. under the hood loosen and remove the 2 host clamps right at the firewall area. Push the metal tubes in to the firewall. Then reach back in from under the dash and pull out the old core. put the new one in reverse order.
