I just got my new 2019 3500 limited this weekend and as I was driving home I noticed the touch buttons for the heated and cooled seats don’t work. Everything else works and that part of the screen isn’t a “dead” spot because buttons in the same place on other pages work just fine. Has anyone else had this issue or have an idea why this might be? I want to avoid the dealer if I have to but might have to have them look at it.
