Working through some HVAC issues and noticed the recircullation button does nothing. My last 964 closed the flap and the cabin noise increased with increased air flow. Do not have a hammer so doing this the old fashioned way...find it and watch it work or not work

So which servo motor works the air recirculation flap and where is it located. Thanks

Been using this link myself for the last few weeks while trying to solve my own HVAC issues

I did use that one over the weekend but it does not answer my question about the recirculation flap. If it is one of the 5 servos under the hood which one is it?

Its the center servo. John's pictures label it #3.

Steve, Rob has of course answered your question but if you look on that link there is a picture of the CCU where Roly has indicated that the recirculation button is servo 3.
