2015 Suburban 5.3. My fans are staying on after you shut truck off. Both fans seem to be running at high speeds. They will run till the battery draw cut out shuts them off. IT is around 40's right now here. Got on internet and lots of guys talking about replacing sender that is near the thermostat. Replaced that today with no effect at all. Used AC Delco sender. Seems that the heat gauge in dash is staying on lowish side as well. Thoughts??????
