I have a 2017 F250 that has a phantom draw. I narrowed it down a couple years ago to fuse #2 memory seat switch. It would kill the battery when sitting for a couple days. Pulled it and it’s been fine for years. Dug back into it today and narrowed it down to the passenger seat at least. When I unplug the one connector from the heated seat control module the amps drop about 700mAmps. Then resting mAmps is around 120 which I’m also curious if that is in range. With it plugged in it pulls 805mAmps. I can also hear a relay click in the dash when I plug it back in. Heated seat worked though with the #2 fuse pulled which is confusing as to why my search is ending up here. Am I getting side tracked/misled? Is there something else on that circuit that could be causing this?
