Actually . . . I believe it is the other way round, that the element in the seat goes bad, and then that causes the module to go. I had a post a long time ago, about replacing the element in my car's drivers seat. . . . from what I saw, the wire to the element is pinched too tight and then frays and breaks - hence no seat heat. The kit has replacement elements for one seat bottom and one seat back. It was relatively easy to do, just be patient and follow the instructions . . . sorry I don't have the p/n for the module.
