I have nothing to add except thanks for giving me a laugh on a cloudy Monday morning in Upstate New York. Parts of this thread read like a soap opera! I loved the guy that said, very dramatically, " do not use heated seats in summer. Ever." There should have been a commercial break there. Maybe your truck knows it's in Florida and it's like, "heat the seat? In Florida? In July? Ummm, nooo." Up here where i live , we don't turn on the heated seats until it gets to 0. (We also panic and swoon when it hits 90.) Sorry, I'm just goofing . I, like most of you , have a reasonable expectation that all features on a new vehicle should work as expected. I think there is a clue, if the owners manual says they start on "boost" for about 4 minutes, then are supposed to hear normally, yours is getting bad temp readings somewhere at about that 4 minute mark. Maybe find a good electrical shop as someone else stated that can trace all the wiring and test all components, then send the bill to Ram!
