63' Ford Falcon Ranchero

Well bud you need to pull that box from under the dash the hole thing and replace the heater core. Dang I havn't work on one of them in a long while. Not a hard job just take your time. It will be bolted through the fire wall look for all the studs with nuts on them that will relace the box unplug the wires from the blower motor. I don't remember but does this have ac if so you will also have to disconnect the ac lines. And they are under pressure so be careful.
