it's good

Has any one noticed a whooshing/whistling noise in the a/c blower when the system is mixing in fresh air.My new MY17 is doing it and my MY15 didn't.Small prob but a little annoying.

Check some of the additional vent/air flow settings in the command menu, maybe something isn't set right.

I had one of the blower doors hang up in my '16 coupe when trying to get more heated airflow to the floor, but it righted itself after re-adjusting the flow and was no longer an issue for the rest of the year I had the car.

Have had the re-circulation on a couple of times.Fresh air door could be hung up.I'll check the settings again in Command and toggle in and out of re-circ.

Try closing all the vents with the blower on 5 or 6 then open them one at a time
