I have a 2012 Charger with the 8.4 inch info screen. When use the ac/heater the recirc mode has a mind of its own. I assume this is computer controlled. Is there a way to put this in the control of the user or at least get it in a mode of on in more situations?

What is the radio sales code in white letters on the faceplate?
Was this a dealer upgrade from a 4.3" touchscreen or a factory-equipped 8.4"?
What exactly does the recirc button do or how does it appear when it acts up?

There is no sales code printed on the 4.3-8.4 touch...

If this was upgraded to the larger touchscreen, a service kit from Chrysler has to be installed to make it all work right. A grayed-out button means that the feature has been locked-out or is unavailable for some reason or other.
The HVAC is fully addressable with the dealer scan tool to find fault codes, etc. There is no manual override. See your dealer.

This is a factory installed unit as part of a package. At time the recirc icon is gray and the when is functional it is lighted and active. There is not prdictable or rational time when it is active. On our other Dodge products recirc is available except in defrost mode.

Recirc may not be available in 'mix' or at temperatures that the interior glass may fog either. See your dealer to diagnose this.
