How to work defroster vents

[Low Profile]

Hello,

I am a new owner of Bavaria E40 sedan. I canmot turn on window defroster vents and do not know what elae to try. I have heat on helm button on with green ligjt and turm on A/C panel to heat and heat comes out of vents eveywhere but the vents for windows. Do you know if there is a switch in engime panel that I need to turn or somewhere else to turm on these specific vents? On the water now and it is dark and foggy. A quick reply would be greatly appreciated.

I know it's an old topic, but the window defroster switch is located to the left of the AC plug on the cabinet housing the TV.
