Thank you for the replies. It is a selling point for me unfortunately. I also have a bad back and it definitely helps for long trips. I'll try to verify again. I'll set the lumbar to press harder against my back to see if maybe the heat pad isn't directly under the cushion? Doubt it, but it's worth a try. Worst case I'll have to get one installed, but if it is supposed to be there, that's a few hundred bucks saved to put toward the Jeep.
