The driver's side heated seat in our Yukon is not working. The passenger side works fine. Is there something underneath the seat that we can check, possibly a wire connector?
99% of those that go bad are the unit itself. The leather bottom has to be unstitched and the unit replaced. Expensive. If you get lucky, and I do mean lucky, the switch will be bad.
I saw that in your post title. If Arnie, who's not been on in a while, says that it's something that he's seen then it's probably exactly what he said.
