Fuse84 Causing Parasitic Drain

[Huero]

2014 Bighorn 4x4 1500 with dreaded Parasitic Drain on Battery. The dash lights are 100% the problem as they come on intermittently as truck is asleep.The good thing, is that I did the fuse test & found #84 to be the problem. Now I’m hoping that somebody can direct me to the module or wire harness associated w it. I think HVAC might be one of the possibilities & know where that is in glove compartment area but maybe somebody has better info

84 is "switch bank / instrument cluster"

I had a recall notice out for my 2022 classic for this maybe it somehow applies to you as well?

Do the lights come on at a routine regular interval? I always suspect a communication problem between the various modules on the CANBUS. One of them probably isn't answering up is my suspicion.

I'd try connecting to the modules with AlfaOBD to see if I could connect with them.

I don't know what module/computer controls the dash lights.
