Electrical problem with dash/radio while plowing

[cat320]

I have this problem with my new 2015 while plowing the the dash would go black and radio while still worked would be frozen on the screen radio still worked but did go off for a sec when it happened. I have been following this on plowsite http://www.plowsite.com/showthread.php?t=161166and from what i was reading they still have no idea what the problem is. my truck has the fisher plow set up . since there has been no snow and i have been driving the truck no problem has occured but i assume it will once it snows again .

 

also my a/c comes on when off when it is in reg vent mode not on the defrost buttons. that does not seam normal to me .

 

does anyone know anything more about what is going on or any fixes that have worked so when i do go to my dealer which will be soon they can fix it.
