ACC Noise

This summer I noticed that when I had the ACC set on 68 and the airconditioning was running I got this crazy noise (whining/grinding, low pitch) when accelerating from 0 and then when the tach. was between +/-1500 and 2000 rpm. I figured it was a tired expansion valve because I didn't want it to be the compressor clutch. Buuut, now that it's getting cold out I have been driving around with the ACC on 72 so it should be pure heat with no AC compressor, right? I am getting it even more pronounced though now, especially more at accelerating from 0 mph, not so much between 1500-2000 rpm. It didn't make this noise last winter when I used the heat. Does anyone have any ideas? The heat is hot and the airconditioning is cold, and the ACC doesn't show any fault codes when cleared. Thanks.
