When you mean AC, you are talking about the compressor right?
What happens if the AC if off and the fan at speed 2? If there is no noise, then it's not the blower motor.
If the noise is still there, then there is a good chance it's the blower motor. Bearing maybe.

If the noise is only there when the compressor is running, then it has nothing to do with the blower motor. Check if the noise is coming fom the accesories belt.
