Drain the coolant.Be Prepared for a few skinned nuckels. First dissconnect your battery You will be working around wiring harness' so just Tobe on the safe side I would disconnect the battery.The easy part is removing both glove boxes, remove the console remove the covers under the steering wheel remove the cover surrounding the the radio and heater controls, now remove the first plastic cover it will have two ports going into the center console, you might have pull back the carpet on both sides to get it out. After you remove that cover you have to remove the next cover that hides the heater core. When that is removed you should see the heater core there are four bolts two top two bottom holding silver bands remove these and the heater core will be loose. When removing everything make sure you get all the screws I missed two hidden screws and broke the cover. Some are torx some are nut heads.Now that is the easy part the hard part is removing the heater hoses from the back fo the engine. If the You are sure the heater core is shot usually coolant on the carpet is a good indicator just snap the two plastic pipes going to the heater core. This will make it easier to access the hoses. There is no easy way to remove these is is a matter of determination and patience. I would never change a heater core without changing the hosesyou will see that it will be worth new hoses because you will not want to repeat this procedure again.
