The dash must be completely removed in order to gain access to the heater box. Then the heater hoses are disconnected and the heater box is removed and opened up. That gains access to the heater core for relacement.

I have a '91 and I believe they're about the same though. The heater core is back inside the glove compartment. You'll probably have to remove the door/tray itself. To get it out you have to disconnect the coolant hoses going through the firewall (engine side). After that there really shouldn't be much to it.

Disconnect the negative battery cable. Drain the engine coolant into a clean container for reuse. Raise and safely support the vehicle. Remove the rear lateral transaxle strut mount, if necessary. Remove the drain tube and disconnect the heater hoses from the core tubes, lower the vehicle. Remove the sound insulators, console extensions and/or steering column filler, as required. remove the floor console outlet ductwork and hoses. remove the heater core cover. Remove the heater core mounting clamps and remove the heater core. This information was taken from chiltons auto repair manual. So good luck and hope it works out
