Hi everyone:

My 01S has a whine. It sounds like it is coming from the front of the car. It's pitch changes with RPMs even while the car is stationary. It goes off - that is the whine stops - if I push the snowflake button and turn the A/C off.

My best guess is that is might be A/C compressor noise. But I'm confused because it seemingly comes from the front of the car. I haven't removed the engine access cover to see if the noise is really coming from the back.

What would your best guess be. Most importantly, could it be noise from the serpentine belt or some other belt-drive auxiliary like water pump, etc.

Thanks
