Instrument Panel Not working

[austinjb711]

I just bought a used 2021 Bighorn with the 6.7, and I can not figure out why I have no lights/response to the instrument panel below the radio. I checked the pigtail on the back of the panel, and it is plugged in, I checked all the fuses, not a single one was popped. I can adjust the trailer brake gain, and it recognizes on the dash, but the exhaust brake, and the tow haul switches neither have lights on or any response once pushed. Any help/ideas would be greatly appreciated.

I suggest joining the sister site, www.HDRams.com. This site focuses on the 1500 DT models, and we don’t have fancy stuff like exhaust brakes.
