'05 and these will roast your butt. They actually get so hot that I have to cut them off to keep my **** from burning. I wish I could give you guys some of the heat. It's annoying they are so hot! They must have cut them down on the '07s....and gone to far.

 

Maybe the KR leather is now heavier. My 05 lariat seats got HOT, way too hot for me. Only used the warmers once. Some may like it, but for me, it was a useless option, right up there with my power pedals and moon roof.

 

I agree, 05 also, the only time I use the high setting is when it is -30 or colder, then I usually have to shut them off before the 10 minutes is up because my butt is burning. My passengers all do the same. I usually just use the low setting and that is plenty warm. I wish they had the dial adjusters like my Jetta did, so you can set it at whatever temp. you want.
