WARNING: This page is about a different car, the 2018 Nissan NV3500 HD, 2018 Nissan NV2500 HD, and 2018 Nissan NV1500. However, it is still accessible from the selected car via links, so may be relevant.
When rear mode door motor is activated while air flow is more than the specified value, front air control temporarily reduces fan speed so that rear mode door moves smoothly.
