2014 Focus A/C door noise

[Henry VIII]

My 2014 Focus' heat & A/C works fine...unless I engage the recirc button.  Then a pronounced rhythmic 'clicking' noise occurs--as though there is something being tripped and falling back into place.  This will continue as long as the button is engaged.  The same thing happens any time I turn the fan off.  But if I always leave the fan on and don't use recirculation, things are quiet. Anyone else experienced this and have a solution?

OK, I'll bite - stop using the re circulation button! 🤣

Sounds like your recirc flap doesn't know it's end point so keeps trying to move past it.  

As above, I'd just leave it switched off, could be a pain to repair buried deep behibd the dash.
