You probably have a shorted heater blower or the little motor on the heater pump is shorted. There is info on adding fuses to these two items in the 300D somewhere in the Forum, use a search for it.

I have seen the circuit boards in the climate control unit fried so bad that the copper is melted and gone. Don't stick another in until you find the short.
