Hello all...new to this forum, but have found useful tips here in the past and hope I'm not duplicating a thread. My problem is that I have a continuous electrical motor of some sort (cooling?) coming from under the dash on driver's side. It's definately not in the area of the stereo....I can't pinpoint it exactly, but sticking my fat head down there, it sounds like it's coming from under the dash, somewhere above teh steering wheel column and below the instrument panel. Any thoughts? I'm familiar with the failing stepper motors as I've already replaced 2 of them in other '05 Chevy models and they never made that sort of noise...guages just failed. Thanks in advance.

 

If you have the DVD NAV system your probably hearing the disc working mine does it all the time when your first ebetr the vehicle.

 

No nav.....

 

You might try an automotive stethoscope to help narrow down / isolate the item

 

I hear that same noice in my 07 Tahoe, but i stops as soon as I open my door. I was thinking this was some sort of fan also but im not sure what it is either. Does anyone else know what it is? I sure would like to know also

 

blower motor?

 

I don't believe so...it's coming from right behind the instrument panel cluster and sounds like a small electric motor. Besides, the sound continues when the heating and A/C system are completely off and only goes off when you open the door or turn the ignition switch to the off postion. Anyone?

 

Does it stay on as long as the door is open or KO?

 

My 2008 Sub makes an odd "whirring" noise that I can best describe as like a faint robotic move type sound. It does if for a few seconds when I get into the vehicle then stops?

 

If you have Nav, then it's the drive powering up.
