Rear Blower Control
WARNING: This page is about a different car, the 2005 Infiniti QX56. However, it is still accessible from the selected car via links, so may be relevant.
When the rear blower control dial (front) is in the OFF position, the rear blower motor cannot operate.
When the rear blower control dial (front) is in the REAR position, it allows the rear blower switch (rear) to control the rear blower motor speed. In any other position (1-4), the rear blower switch (front) controls the rear blower motor speed regardless of the rear blower switch (rear) position.
