The heater core is behind the AC evaporator core. You must remove the panel with the venting on the passenger side. Then you must disconnect the two AC fittings inside the engine firewall. You do not have to remove the AC evaporator core, it will swing somewhat out of the way so that you can get to the heater core. There are several clips and screws holding the heater core in place that must be removed. Then you are able to remove the heater core. It is about a $35.00 item.
factory recommendation is to cut a hole in the inner fender well to access/replace it.

It should be on the passenger side under the dash or in the engine compartment on the same side. It will be in a housing that will have to be taken apart.

This is one of the worst cars to have to replace a heater core in. Typically, the best way is to remove the passenger side inner fender. Some of the later inner fenders do have an impression in the inner panel that allows you to cut it, pull it down and access the area. Either way, it takes several hours to do the heater core on that car.
