Sudden multiple electronic issues

[weekender]

I have a 2012 RAM 5500 with a Cummins 6.7 Diesel, Aisen transmission. Aroinf 125,000 miles. Headed out for the weekend and discovered I had no turn signals. Then I discovered the tow/haul and exhaust brake buttons didn't work (The emergency flashers in the same dash row works). Neither do the windshield wipers and washer. Neither do the control buttons on the right side of the steering wheel to watch DEF levels and fluid temps. The left side cruise control buttons work fine.
Does anyone know if there is a fuse or sensor that controls this assortment of functions? The truck worked flawlessly 10 days prior.

Has there been anything done to the truck since the last time you drove it Sir ?
Anything at all ?

I made a trip in March THAT was a disaster. DEF issues. Dealer replaced DEF injector and harness, transmission harness, and then they accidentally punctured my radiator so I got a new one of those also. I drove another 200 miles home and everything seemed okay. I drove another 70 miles without the trailer, no issues. The last time the vehicle was used I made a 460 mile round trip during which it's performance was flawless. Parked it for 10 days and all this starts.
