With the panel off, have you tried to put the vehicle in accessory mode to see if you can hear anything engage?

 

Such as what? I'd expect anything actuated to be moved by servos. All the servos work, it's just that one of the assemblies that is meant to move seems to be stuck.

Edit: I see what you mean. I haven't taken the white panel off as it's dark outside and I need a reasonably working car tomorrow (our weekend is Friday and Saturday). I will see what my next move is tomorrow... Very annoying.

 

Oh, no worries! The hunt continues, I see .... Good luck!

 

I'm still watching this thread closely. Do the servos reach all the way to the drivers side and where exactly did you take that photo?

 

I had the classic broken air circulation assembly from forcing open the damper door to change out the cabin filters. My issue was that recirculation/fresh air circulation button didn't do anything, so different issue from yours. I had my issue fixed by replacing the broken swingarm / gear tabs with a new assembly part #87020A.

I'm only bringing up my experience because the picture on post #15 looks very similar to the broken swingarm that I had fixed.
