So what I did was take the in-cabin filter out and spray the top of the motor/fan with a ton of WD 40 (with the fan off and then with it on). Put filter back in. All noises are gone. Better than ever.

Well see if and when the squeaking sound comes back.

Anyone else have this issue?

So you soaked with fish oil.
