My 2012 had a defective sun sensor/multiswitch. Repacling this multiswitch helped greatly, and I am no longer fried (or frozen) alive by leaving the car set to my desired temperature. It also allowed me to hit the recirculate button and have it work. (Before the multiswitch replacement, it would go into recirculate when it felt like it, and then would go back off again after a few minutes.) Now, I can generally put it in recirculate mode, even in Auto, without explicitly turning on the A/C. On manual, it also generally works in dash vent mode, and combo dash and floor vent mode. It does not allow me to turn it on in any other mode.
