A solution to keep recirculation on by pushing a button even when the defrost mode is on. In other words, a wire to override the defrosters so recirculation can be on in any mode. I thought about closing the diverter and disconnecting power to that air inlet servo however i prefer a electrical solution instead of a mechanical one. The A/C amplifier seems to use communication signals ECU via CANbus system which may complicate the solution. From youtube i heard you can hold the recirculation button down for 5 seconds to keep it on however this has to be done everytime i turn on/off the car. i added a couple pics of the air inlet servo. Again i want recirculation on at all times no "fresh air" or "outiside air."
