I just swapped my panel out with a used one I picked up on ebay and it has fixed my problems. The panel was a good deal at only $65 since it was missing the touchscreen bezel and some of the plastic housing was damaged. I took the electrical parts I needed from this panel and installed them into the frame of my panel. Problem solved. Since this is a used panel of equal age as the car; I don't expect this fix to last forever before it starts to have the same problems again. I'll be trading in my Edge soon anyways though to get something more efficient for a new commute I'll be starting in a few weeks. Regarding the idea of permanently disabling the faulty buttons, I'd be hesitant to try any irreversible modifications to your panel unless you have another replacement panel on hand as a backup. I also tried just unplugging the whole control panel from the head unit and confirmed the system will not work without the control panel harness connected. Putting a hole through a sensor might make the whole system go out of out of control since it will still be trying to control and sense the electric field for that particular sensor. If you're ok disabling all the touch buttons, you could maybe try leaving the ribbon cable from the touch panel disconnected from the PCB control board and then see how the head unit then responds to this.

I'm having the same issue on my 2013 Edge Limited. The fan will increase to full blast and to full heat which is really annoying in the summertime. It will also change the audio source occasionally switching from SXM to FM. I've found that rubbing the palm of my hand firmly over the capacitive touch buttons on the control panel and then resetting the climate on the touch screen will temporarily pause the problem; usually until the next time I drive the car. I now officially HATE capacitive touch buttons and will never buy a car with this type of controls again. I went as far as to take my radio/climate control panel out of my Edge and then open up the panel housing to see if there is anything that can be done to repair whatever is causing the false touch inputs on the panel. What I found is that on the backside of the plastic control panel face, a thin flexible membrane circuit board is glued to the plastic. This board contains the capacitive touch sensors which must be in perfect contact with the plastic face to work. Over the years of heat cycling in the vehicle, bubbles have started to form between the circuit board and the plastic face. My theory is that these air bubbles cause enough of a disturbance in the electric field to falsely trigger the button as being "touched". I'm a mechanical engineer and don't fully understand capacitive touch sensor technology but talking to some EE's at my work they agreed that this is likely the problem. I can't think of anyway to repair this. Trying to remove and re-glue the flexible circuit board will likely damage the board in the process. Does anyone know how interchangeable the FCIM radio/climate control panels are in the Edge? The part number on my panel is DT4T-18A802-CB. I can't find any information online which identifies what the final two letters ("CB") of this number mean. Searching for used replacements on Ebay I can find models ending in "CL" and other versions. I cannot locate a "CB" version anywhere. Has anyone tried replacing the FCIM with a model different than what was removed from the car?
