I need location of the dash control unit (part no. BA1Z-19980-J)

What is your question?

I have removed the dash control front bezel, the touch screen unit, and the CD player; I thought the AC/heater control unit would be in the cluster behind the bezel, but I don't see it. The wiring harness that connects to the front bezel, which I think services the touch buttons for AC/heat?, leads into a bigger harness bundle and goes...somewhere? A diagram, step-by-step, and/or video of how-to would be awesome...

What makes this problem better or worse?

intermittent periods where the heater controls do stuff on their own

How long has your 2011 Lincoln MKX had this problem?

couple months
