Climate Memory

My Pacifica “remembers” the climate settings in weird ways and I’m hoping someone can tell me the pattern. It turns on the seat warmer and steering wheel if it’s cold as well as the last HVAC setting. And then sometimes it doesn’t. It turns on the AC if it’s hot out but not the ventilated seats. Sometimes it doesn’t turn on anything even though it’s cold. I’ve spent three years trying to casually isolate it. Close to actually keeping a notebook of temps and how the car responds. Does anyone have something from Chrysler on this? Anyone else’s car do this?
