AC and different fuse panel

[Fubar]

Evening!!! Been following your videos for a bit now and I appreciate the advice. I have a 16 pro star with Cummins isx. My ac check light comes on daily now and I have to pull over shut truck off disconnect battery cable wait and tighten it back on and it will work till it decides to throw code again. I ran diag and it came with spn3984 blend door actuator. I opened my dash flipped through settings it works yet every 20/60 mins it faults and blows hot air. Really bad In Florida and Texas. Brand new owner op and it’s sucking. Your videos are good but my fuse panel is a little off compared to others. Wondering if I could get some insight on which or what to do?
