How are Info Center Compass and AC/Heater Blower Motor Connected?

Hello -
I have a 2007 Jeep Commander 4.7L V8 and I occasionally notice my in-dash compass will display dashes instead of my direction of travel, and when this happens, it also cuts out the blower motor for my AC/heater. Sometimes it returns momentarily, and it always resets when I turn off the engine and restart. It doesn't happen every day, not even weekly, but enough to make me wonder what's going on. Can anyone shed some light on this? Thanks!

It's "Junction Block" not box.
Another tip is there are 3 large plugs connection all the many circuits, reseating them may help, but they are not easy to do.

You pull the gray handle to release it. There is a step by step in the attachment on how to do it.

Think those plugs kind of twist in - pull up on one side to rotate. Probably the cable side?? As I said I never tried it. If you do get them out please let me know how you did it and I'll add it to the "Junction Block" post.
