Blower Speed Control
WARNING: This page is about a different car, the 2008 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.
Blower speed is controlled based on front and rear blower control dial settings.
When blower switch is turned, the blower motor starts and increases air flow volume each time the blower control dial is turned clockwise, and decreases air flow volume each time the blower control dial switch is turned counterclockwise.
