I had the dealer install mine, and the switch is kinda in a re****ed spot. I assumed the buttons would be in the center console, where the dummy caps are filling unused buttons. They put the switch on the lower door side of the seats, where you adjust seat positions.
!!!!! I used to be stationed in Virginia, and I take my leave in Oregon, so there used to be a reason for the heated seats!
The best one I can think of now, is for the wife. She loves the heater on her lower back when we take turns driving up to Portland.
