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.
