Doh! I've seen repeated heater element failures from people dragging their ass in and out of the seat, rather then lifting themselves in and out. Jeep Grand Cherokee's were bad about it to the point Chrysler redesigned the bottom element pad. Since your tall I doubt you have that problem but just a thought.
they call that the butt drag (BDRAG ) failure huh? Well i'm actually the opposite I pull myself out of the seat and step right on the side step to avoid wearing the leather if anything else...damnit.
