I’ve had an on going issue just wanted a second opinion before I order the part which I believe is the fcm my interior lights, dash lights, ac blower fan, bed light, power locks, and wipers intermittently do not work my blinkers work outside the truck but do not show up on the dash I took the fcm out this morning to get the part number off of it and now my radio doesn’t work anymore if anyone has experienced before some input would be nice I haven’t seen much on this online but the fcm controls all that why I assumed it’s that

 

Check wiring to the cluster. Had a Cummins that did something similar, and it was one pin that jarred loose from cluster wiring connector
