The drivers side heated seat in my '01 A4 does not heat up completely. The sides get nice and toasty...but the butt and back do not heat up at all. Does anyone know how to go about having this fixed? A friend of mine suggested CarToys. I'm hoping someone here has some experience with this and can help. I commute a lot and my @$$ isn't big enough to benefit from just the heated sides of the seats.Thanks.
