The heater fan on my 2005 RX 330 makes noise when it runs - particularly on low speed setting. Sounds like it needs to be oiled or something.

It does not sound like it is hitting anything. More like a bearing problem? It does not sound like it is hitting anything. More like a bearing problem?

Ah ok. Well depending on the fan type, Blade or Turbine, some may have a replacement part/bearing others will have the bearing permanently mounted in the motor (no servicable parts) I'd say try a small squirt of WD40 if u can actually pinpoint it but if its the motor bearing it wont help much. It may even drip into the motors brushes Ah ok.
