When I’m using the AC in Manual mode, and then enable Auto mode, there is a change in sound - even when all functions remain the same. For example: manual mode, 72 deg, fan speed 5, AC on, front and rear vents on, and recirculate on. Then if I turn in Auto mode after cabin has reached set temp, all the settings stay the same (fine), but I hear a slight increase in sound as if some fan speed is slightly increasing. Anybody know what might be happening that I’m not seeing change on the climate screen?
