Rear Blower Control
The primary control for the rear blower is on the front
climate control unit, located on the instrument panel.
Only when the Rear Control Icon is illuminated do the
second row seat occupants have control of the rear
blower speed.
The rear blower control, located in the rear overhead
console, has an off position and a range of blower speeds.
This allows the second row seat occupants to control the
volume of air circulated in the rear of the vehicle.
