funny sound when Fan is one.

[BatKing]

Hi,

My Final stage Resistor is bad and the new one should be my home tomorrow. However there is something strange related to the fan.

before my FSR went completely bad, I heard something when the Fan is turned ON. the sound like some small smooth electric motor. something like "WOooooo.... WOooooooo" in pulse. This is not happening all the time.

Now since my FSR is bad and the fan won't be off even the car is off. so I took the Fan Fuse out and waiting my online ordered FSR to come (Local Dealer wants $137.xx + tax ). and I didn't hear the funny sound for last 2 days when I was driving. the Fan still turned on, but there is only outside fresh air coming when at freeway speed.

Then today I hear the sound again, and since it is the 1st time I hear the sound when there is no Fan Action, so I can hear it pretty clear and trace the source of the sound. It is in the engine bay. I don't know where exactly it is, but it is on the driver side and very close to the Power Steering oil carrier/reservoir.

My question is, if this sound is related to a bad FSR? if I turn off the fan control, the sound will be gone.

Thanks.
