Air recirc/fresh....

[Jake335i]

I was working on my car trying to clear a SES code with my scan tool and saw a fault:

Fresh Air/Air Recirculation flap motor - it was highlighted in yellow so I believe that means it is a "past" code and not presently found..??

Anyway, I leave the fresh/recirc air on "A" (auto) mode. However hitting the button does not create an increase in fan motor sounds, as it does with all of my past vehicles.

I have only had the car a few months, when I got it it really smelled, after deep cleaning, new cabin filter, removing the decayed bird from the intake, among some other tricks, the smell is completely gone. Anyway, how do I know if the system is currently working or not??

The plastic flaps in the front of the engine, always seem to be closed....not sure if that is the same system or not...?? Perhaps that is just a engine warm system to warm the engine faster in cold weather...??

Any way to test, or at a minimum, just get the system set to "fresh air." The fan has always seemed a little loud to me, if I had to guess I think the system is stuck in recirc mode...

Thanks in advance...
