I had the same problem on my 92 Grand Am. It was quite a hassle and I still don't have it completely fixed. I replaced the heater core, but in the process, I broke a plastic shield in front of it so warm air leaks out. What you have to do is remove about 40 little screws that hold all of the plastic covers on, including the covers under the steering wheel, around the ac/radio, and under the glove box. You must also remove the center console cover. The plastic cover directly in front of the core has no srews but plastic pins. It is difficult to remove. Try not to break it (like I did). Once that is out of the way, you can remove the screws hoding the core in place and from underneath the car, unhook the water hoses. Then the core can be taken out.
