As understood the blower fan is not part of the recall only the connector wire and resistor but I am convinced that somehow the heat could have damaged my blower fan. I am now getting the attached sound when the car is at operating temp and under load. Does not appear to be mechanical and electronic.
Resistor and cable replaced this month by bmw under the recall but the noise was present before the recall.
Does anyone else have the same issue?
