The heater blower/fan is controlled by the socalled sword, which sits behind the front console. The radiator has nothing to do with that. Read this here, the sword can be repaired. Another problem area could be the IHKA module, which sits behind the sword and control the complete heating and cooling system. Also this one has a capacitor which sometimes fails. All connections should be resoldered due to old solderings becoming bad.
