I have the same problem. Do you have an update on your situation?

On my 2010 S80 (3.2 - 2WD) the fan doesn't blow most times. Only at highway speeds will the fan blow, very lightly and occasionally. Heat or AC, fan still won't blow.

I do have a DTC for the ECC module, where is that located to replace?
You need to have that code read, as it probably isnt a fault in the ECC module (thanks for calling it that, and not the ECC!) but one of the other components. It could just be the blower itself.
