-Remove the four screws attaching the console assembly to the console panel front support.

-Remove the four screws attaching the console assembly to the instrument panel.

-Lift the console assembly off of the transmission tunnel.The console assembly includes a snap-in finish panel which conceals the heater control assembly attaching screws. To gain access to these screws, it is necessary to remove the floor console

-Disconnect all underhood wiring from the main wiring harness.

-Disengage the rubber grommet seal from the dash panel and push the wiring harness and connectors into the passenger compartment.

-Remove the three bolts attaching the steering column opening cover and reinforcement panel. Remove the cover.

-Remove the steering column opening reinforcement by removing the two bolts. Remove the two bolts retaining the lower steering column opening reinforcement and remove the reinforcement.

-Remove the six steering column retaining nuts. Two are retaining the hood release mechanism and four retain the column to the lower brake pedal support. Lower the steering column to the floor.

-Remove the steering column upper and lower shrouds and disconnect the wiring from the multi-function switch.

-Remove the brake pedal support nut and snap out the defroster grille.

-Remove the screws from the speaker covers. Snap out the speaker covers. Remove the front screws retaining the right and left scuff plates at the cowl trim panel.

-Remove the right and left side cowl trim panels.

-Disconnect the wiring at the right and left cowl sides.

-Remove the cowl side retaining bolts, one on each side.

-Open the glove compartment door and flex the glove compartment bin tabs inward. Drop down the glove compartment door assembly.

-Remove the five cowl top screw attachments. Gently pull the instrument panel away from the cowl.

-Disconnect the speedometer cable and wiring.

-Drain the coolant from the cooling system and remove the hoses from the heater core. Plug the hoses and the core.

-Remove the screw attaching the air inlet duct and blower housing assembly support bracket to the cowl top panel.

-Disconnect the black vacuum supply hose from the in-line vacuum check valve in the engine compartment.

-Disconnect the blower motor wire harness from the resistor and motor head.

-Now go under the and remove the two nuts retaining the heater assembly to the dash panel.

-In the passenger compartment, remove the screw attaching the heater assembly support bracket to the cowl top panel.

Now you need to install the new one:

-Check the heater assembly drain tube to ensure it is through the dash panel and is not pinched or kinked.

-Back under the hood, install the two nuts retaining the heater assembly to the dash panel. Install the air inlet duct and blower housing support bracket attaching screw. Install one screw to the retainer bracket below the heater assembly to the dash panel.

-Connect the blower motor ground wire to ground and the harness to the resistor and blower motor lead.

-Connect the black vacuum supply hose to the vacuum check valve in the engine compartment.

-Install the instrument panel and floor console by reversing the removal procedure.

-Connect the heater hoses to the heater core and fill the cooling system. Check the system for proper operation.

Sorry to hear about the heater core. I feel your pain as Ive done a few of them. Make sure you have a full weekend. Can be done in a day but sometimes is a little overwhelming for one day of sitting w/ a dash on your lap....
