Aztec ceiling fresh air vents - butterfly control valve location

[Coopere]

I'm wondering if anyone knows the location of the fresh air valves in the ceiling on the Aztec. Are they positioned above the aft cargo area headliner?

My control knobs seem to work however they don't seem to reduce the airflow to the ceiling mounted fresh air vents on either side I would like to take a look during my annual and see what I can find. I'm wondering if the push pull wire has come off

Thanks
