I have a 2018 3.6L V6 Laramie that recently developed an issue with the AC. I can not get it to shut off. The Auto and AC lights are not on yet it continues to blow cold air. I have turned the climate temp from low to 60 degrees in hopes of having it shut off but to no avail. I have checked the relay and it tests fine. I even swapped it with another one and it still continues to blow cold. I have read all of the threads I could find regarding AC issues but nothing seems to cover this issue. Soemone had mentioned the AC Heater Control Module as the culprit but I don't know how to test this. Same goes for the humidity sensor. I'm looking for the path to follow to get this corrected without having to spend $500+ for the entire center stack control panel.
