Turn on Re-Circulate when Floorboard/Windshield selected?

Does anyone know if there is a way to reprogram the HVAC so that you can have re-circulate on when you select the air output to be the foot well and the windshield? I know some cars have weird ways you can reprogram like you hold some button down, turn the ignition on, etc.

Disclaimer - I know it is like that for a reason, this is just a preference thing

 

I'm thinking you probably tried this, but some cars/trucks and Toyota's especially in my experience the button has to be held down for a good 5 sec or so to stay on recir, but then it will usually default back after the truck is shut off.

 

These are the HVAC options in Carista. There may be more available through techstream.

Heater & A/C

• Temperature dial calibration
  -2°C / -1°C / *NORMAL* / +1°C / +2°C
  
  
• Auto-increase blower speed when front defroster is on
  *YES* / NO
  
  
• Auto-turn on A/C when AUTO button pressed (if needed)
  *YES* / NO
  
  
• Deactivate front defroster when AUTO button pressed
  *YES* / NO
  
  
• Open vents to outside air when ignition is turned off
  *YES* / NO
  
  
• Fan speed reaches its target…
  SLOWLY / *NORMALLY* / FAST

The reason is . . . if you are trying to de-fog, de-frost, you do not want recirc on.

I gave it a shot and no dice. I held it for a lonnnnnngggtime and it wouldn't recirculate

Sorry, I only addressed the. "Reason" part. The first part is NO.
