I am sorry that you have not been helped yet. I jut came online and saw your question
Ok, I am going to to need the vin number in order to pull the schematics to see where the issue lies.
Ok, fuse 32 is for the stepper motor of the power steering unit. Let me pull its schematics and review them.
Everything I am showing points to the stepper motor making the noise - see attached diagram of location - it is mounted to the rack and pinion.
noise can be deceptive on its origins. the noise can be transmitted thru the rack and pinion to the passenger side. There is nothing else on fuse 32 circuit to cause a whirring noise.
I would use a length of vacuum hose and put one end down on the driver side of the rack and pinion and listen thru the other end to see if noise is amplified. If it is, then you know it is the stepper motor whirring.
I am not sure what else it would be, so I will opt out and see if another expert may know
