You didn't mention in the earlier posting that you were replacing just the
blower motor. You need to remove the box to replace the heater core, but
you usually can replace the blower motor by just tipping the leading edge
of the box up sufficiently to take off the plenum to the evaporator box and
extract the fan/motor assembly. You have to loosen that seal at the
firewall, but it's usually gooey enough to reseal itself, or you can add
sealing material before lowering the box back into place.
