AFM issue? Stuck in V8

[16SLE91]

So this morning I noticed that my GMC Yukon is stuck in v8 mode and sounds really strange, almost whining. Slight rough idle. Any ideas??

AC clutch dragging? Would have to hear it and then, maybe, we can tell.

Certainly sounds labored, like it is being dragged down by an accessory but am no expert on noises anymore.

Consider yourself lucky - Most people have to pay for that feature!
