The issue is fairly common on the 2013-2016 Lincoln MKS. The temp starts going up by itself to HI and if you need to rub the FCIM temp controls to get it to stop. Starts even when you try to turn off. A repair estimate was over a $1000 so I tried cleaning control panel but that did not work. Ended up replacing the FCIM myself which I got on EBAY but now it goes LOW by itself. 2 Bad FCIM panels in a row?

Second fix, but it's still not working. At least temperature goes down all by itself, now that summer is here. The front control panel (FCIM) was a replacement for one that temp kept going up by itself. My wife suggested we keep this FCIM for summer and I can use the other one in the winter.
