SOURCE: Pontiac Fiero Heater Core
no its actually really easy i just did it about 3 weeks ago. right under the dash on the passenger side the is a black box unscrew the cover on the side of it and the heater core is right there then you have to disconnect the hoses under the hood which might be the hardest part after that unbolt the straps holding the heater core on. I keep the straps on till i get the hoses off because then the heater core don't move when you are trying to get the hoses off. Then all you have to do is put it back together.

Okay. warm up vehicle, get radiator hoses hot. Turn on heater, fan on low. Grip both rubber heater hoses close to the firewall, from the engine compartment side. They should be too hot to hold for long. If they are not hot, then you have a lack of coolant circulation to the heater hoses. If they are hot then access heater core, behind glove box area. Blend door which moves as you chose HOT or Cold, should be cable controlled, move the controls and be sure the door is actually moving. Keep me posted

i do believe you have to take the passengers side dash apart behind the glove compartment. go to autozone and get a manual or go to the library and check the chiltons manual. this is not an easy job. how bad is the leak? if its not bad these heater cores are made of all aluminum. i would buy a bottle of that radiator additive and see if that takes care of the problem first. it only cost about 5 bucks a bottle and it may permanantly fix your problem.
