Hi, Need more help. My 62 came with BMW seats, unfortunately, the Driver's side doesn't work, meaning it doesn't move forward out back, or any other seat function other than lumbar support. Furthermore, when I went to visit Torfab about an unrelated issue, they told me it wasn't installed properly and was dangerous. I've had so many other issues that I hadn't really gotten there yet. Anyway, the seat was wired to the working passenger seat, so "its not hooked up" isn't true (or maybe it is kinda true). So, I pulled the seat and am digging in. Question is how do you trouble shoot? I searched the interweb and it suggested that the controls fail, which is totally plausible, but I hate throwing good money after bad. Any BMW seat experts out there?
