how to shut off AC recirculation when it goes on automatically
 

2012 Unlimited standard AC controls, when driving my AC goes to recirculation by itself. the only way so far I have found to turn it off is to engage the recirculation button then push it off again. but after a couple of minutes the recirculation comes back on automatically. is there a way to only have recirculation on when I push the button, besides turning the temperature nob to warm?
