Roof Heater Vents

Can anyone explain the route the air takes to get to the roof vents so I can look for blockages or stuck flaps?

Don't know about the route, but a lack of flow would suggest either the fan isn't running at the speed your telling it to, or more likely the pollen filter located in the scuttle area is blocked.
I'd be inclined to do a scan with VCDS for the heater system, it might be able to shed a bit of light on whats going on, I think the flaps are all electrically operated, never seen the dual AC setup, but would guess its possible either a linkage has come off, or a motor has got stuck.
The righthand set of buttons relate to the rear heater on the single zone setup, can you hear the rear fan speeding up as you increase the speed?
