That is quite absurd. Here in Canada my blower motor tends to make unpleasant noises on cold days, but it sounds like you have ruled that out as a possibility. I was gonna say the vent changer motor but if your vent changer is working, then not likely that would be it either. Maybe a fan or something the back of the stereo head unit? I don't know about the stock unit, but I've had a few aftermarket head units with fans and such on the back.
