When I replaced the heater core on my 95 Suburban, I seem to remember having to disconnect the A/C lines on the firewall for the evaporator. There were also several nuts to remove on the engine firewall side from studs on the heater box that pass thru the firewall. It is definately a lot of work.

As with all vehicles it seems the first part that they build around is the heater core. It is under the dash above the floor housed in a black plastic sealed box. Sealed with goop. Locate that box and start removing everything around it that is peventing taking the cover off. Of course disconnect the heater hoses under the hood a thefirewall.
Warning it is never as easy as it sounds.

SOURCE: how to remove heater core
You start by draining off some of the coolant. Open the radiator drain petcock on the drivers side of the radiator. You only need to drain off a half gallon or a little less. Loosen the two hose clamps leading to the heater core. You may have to twist the hoses slightly to brake them free. Now the fun starts. Remove the glove compartment by removing the eight screws at the bottom. With that out of the way you should be able to see the hearer control box. On top of this box is two cables. Remove them by gently prying off the slip clamps with a screw driver. there is also a holding clamp on both of the cables simply remove the screw on both clamps and the cables will come free. Now you remove the three bolts holding the box to the firewall. The ducts attach to the box in different ways depending on what model of suburban you have. Some snap together but most will have screws. Look closely before forcing the ducts apart! Almost done. there are three bolts under the hood on the passenger side. One is on the top of the a/c box two are below it. Only one is difficult to get to. It is located right below the blower motor housing. The easiest thing to do is to use a long extension and a universal joint with a deep socket. Some people take the inner fender off but I don’t recommend it as 16 bolts hold it in place. With all that done the box should be pulled strait out, just before it hit’s the dash, drop it down and out.
