Air Flow Control At Actuator Operation
WARNING: This page is about a different car, the 2011 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.
If the mode actuator starts when the air flow corresponds to a voltage of 8.6 V or more applied to the blower fan motor, the A/C auto amp. performs control that fixes the voltage applied to the blower fan motor at 8.5 V, temporarily decreasing the air flow and ensuring that the mode door operates smoothly.
