How do I get rear vents to work, blow warm or cool air.

Hi oldole,
Does your car have 4-zone aircon?
If so, the control should look like this...


4-zone Rear aircon control
To switch the rear aircon, go to the main climate control page on the screen. Go to OPTIONS, and there are the various controls for the rear aircon.
You can set it to ON, OFF, 'match driver' and some others.
If you don't have rear aircon, then the back and front should be the same temp etc.

Yes, as above. If this control panel is not present, then the rear vents are simply extensions of the front system, and the rear passengers can only open or close the vents; they don't have separate control of the system.

If you do have that control panel and the system doesn't work, then, um... I don't have an answer for you.
