Well, it looks like the FCA engineers have this issue squarely nailed. The manual states one setting but yet some owners have heated wheels that one setting and some have at least two settings. I love my 5th gen RAM but I have zero confidence in the manual or if we should have 1 heat setting or 2. Regardless of what the manual states, my heat changes with the seat setting. Like I said before, maybe mine is broken and it’s only supposed to have a single setting - but I won’t be asking anyone to look at it. They fix the wheel heat it might make the brakes squeal...
