I have a 2013 ford edge Limited with the black capacitive touch screen FCIM. Having issues with the AC button turning itself on and off. Have done the reset, checked fuses and everything else. Seems it is the FCIM that is bad and needs replaced. I have a replacement ordered but it is 4-6 weeks out. I have seen post where someone has opened it up and used a heat gun to make the control pad stick together and remove air bubbles. I was going to try this but cannot figure out how to open it up to get to the yellow control pad. Can anyone help me get this opened up to try this? Pictures would be great.

How did you remove the faceplate to get to the control pad? I can't figure it out.
