Hi everyone, I'm new here and I have a question about my 2000 TL. So I know that the TL has seats that heat the seat cushion of both the driver and passenger side, and the lower and middle back portion of the driver seat. My back portion of the driver seat only works now, and seat cusion of either side doesn't work. Do you think there is a fuse or something I could replace, or is it a more complicated problem. Any input would be appreciated, thanks!
