In regards to the seat heaters, mine ever since new has had issues of only heating the backrest. I had it repaired once only to have it break 8,000 miles later. I've just learned to deal with it. The backrest is better than nothing. Besides, I've read a few post on here about nightmare fixes for this problem that left the seat upholstery shifted, loose and saggy to say the least. And again, check your interior lights switch and welcome to the order!
