Hallio

For anyone that comes across this with a slightly newer model, I just followed these steps and fixed the heater element for the seat base on my 2016 Yeti and it all went smoothly. Some (minor) points to note : 1) The seat is heavy and bulky but definitely easier to get to everything if you take it right out. 2) I couldn't get to the spline nut behind the seat belt stalk to remove the seat-back but I found just removing the two lower ones (one each side) I could rock the base forward to create a gap and remove the old element and pass the new one's cable etc through easily enough. 3) The height adjustment lever seemed to have a little clip on the inside face that needed to be pressed in and then it slid off easily. 4) The rear-most connector in the floor under the seat (the small black one) was not at all clear how it came apart - keep fiddling and you will work it out! 5) Pressing the seat cover retainers into the C-clip was easy and didn't require helping hand. It took me two hours including tea breaks and occasional cursing - now I have a warm rear end after putting this job off for more than two years!
