Claim 0:
1. A method comprising:
by a controller, responsive to input of a particular user selected blower setting
operating a blower with an initial power having a predetermined value based on a maximum setting for an operating voltage or duty cycle of the blower related to a first noise and vibration level that is independent of cabin temperature provided that the cabin temperature is outside a predetermined range corresponding to a moderate cabin condition as defined by a first threshold cabin temperature and a second threshold cabin temperature, the predetermined range being therebetween and independent of a target temperature and the particular user selected blower setting; and
operating the blower with an initial power having a value less than the predetermined value as defined by a percentage of the predetermined value provided that the cabin temperature is within the predetermined range corresponding to the cabin temperature being in a moderate cabin condition, the value less than the predetermined value corresponding to an adjusted operating voltage or duty cycle that is dependent on the cabin temperature, with the adjusted operating voltage or duty cycle having a value based on the cabin temperature within the predetermined range and having a second noise and vibration level, less than the first noise and vibration level.
