Vents not working - any setting

[CLS70]

Hi
In the last week or so, the Vents settings (X5 e70 3.0 si) are not working at all. It does not matter which setting I select in iDrive or how I set the distribution of air (Cold/Hot, top/middle/foot vents), there is no air coming out; barely a whisp in the windshield defroster vent. The fan works and it changes speed but no air is coming out. I have tried several combinations (auto, individual, AC, recirc on/off) with no discernible change in air output.

Before I start dismantling anything, has someone come up with this issue? I have searched already and found nothing (besides the guidance to change stuff / settings in iDrive....) Battery is less than 1 year old and I have even hooked up a charger. No electrical issues or alarms.

Thanks
