When you say fan bearing, is it the cooling fan? Cause I can't hear it when I open the hood, only when I'm driving the car

Take a good guess at which fan circulates cabin air

So the blower motor under the glove box? Does that spin even with the a/c off?

No, but if spin you have an issue with your AC controller and or front SAM

Oh ok, because the car makes the noise even with the a/c off, but the a/c works normal and everything.

Well, you can adjust the fanspeed under the dash faster and slower, see if then changes tone.
