We just took delivery of our JX and still haven't gone through all the manuals to see how things work. Since we've had several newer Nissans, many of the features work pretty much the same. One thing I can't tell if its working correctly is the Rear Air control button on the dash. It doesn't seem to want to over-ride the rear controls unless you physically turn off the switches in the second row seat area. On the QX and Armada, you could shut off the rear air from up front. I'm wondering if there is something I'm doing wrong, or if the switch is defective. Anyone having an issue with this?
