First, does the blower motor work, but the air just doesn't get hot? If this is the case, combined with the overheating issue, I'd say you have a blown head gasket that's pushing exhaust gases into the cooling system. This will create bubbles that get trapped inside the system and heater core, which prevents coolant from circulating, thus no heat.
