Ok, I have and 06' 955, 96k miles. It has standard a/c, from what I gather no rear a/c, just rear outlets at the back of the console for the rear passenger area.

A/C blows cold. 1st the 2 center outlets above the audio in the dash stopped blowing (far left and right outlets blew fine). Next the outlets at the end of the center console for the back seat stopped blowing air. Now even the outlets at the far left and right of the dashboard stopped blowing.

If I use the a/c controls to route all air to the floor outlets below the dash... they blow cold air. However on a hot day, the floor outlets do not produce enough volume to cool the whole cabin, at least not quickly.

You can hear the fan blow blowing full force but nothing out of the dash anymore. I've tried all routing options in the controller, including mixed routing (outside and recirc., etc) to no avail. I have seen that these vents have electrical connectors, but how likely is it that all of the them are faulty now?

I've checked possible fuses that control the vents and found nothing. Can anyone help me on this, please. Indian Summer blues.

You'll have to do some under the dash diagnostics. There are a number of stepper motor devices that open/close flaps to direct air around the vents on the HVAC system. These can fail. I'm sure a search here will turn up more on them, but the troubleshooting would involve seeing if they work. If not - and they all stopped working it might point to the HVAC control unit, or you could be just unlucky and have multiple stepper motors fail at the same time.
