Does anybody know where this is? Right drive Skoda MK3 Fabia with climatronic. Want to see if it moves when I change settings on the system. 

 

Behind glove box maybe? 

I assume you mean the flap that closes the HVAC intake to recirculate air inside the cabin?  This is located under the scuttle panel on the passenger side.

 

@TheFozzy Think so, I have the climatronic. Does this open and close the flaps to alter air flow through the vents? Mine is playing up sometimes works, sometimes decides not to work properly.
