2018 Laramie, heated and
2018 Laramie, heated and ventilated seats. The heated seats are so weak, they don't take the chill out of the leather. (10*f outside) The 17 we test drove worked fantastic. The only interior difference noted was the 18 had the aux switch & 5 seat option vs the 17 was the 6 seat without the aux switches.. I personally inspected the operation in our new 18 funding the seats were in fact getting voltage corresponding to high and low command. This leads me to believe that there is wattage difference between the years and possibly interior option. The owner's manual states, at initial request the seats will receive a boost to build the heat quicker and after a 4 min period they return to normal operation. After 60 mins on high they automatically switch to low and off after 90 min.
