Yesterday I noticed that I could not move the driver's seat in any direction. There the 2 switches: 1 for the seat up/down and front to back, and, the switch to tilt the backrest. None of the switches are working and no motors sound like they're being energized. The passenger's side power seat is fine. I've looked in a schematic for the fuses and it lists a fuse for the passenger's power seat but nothing for the driver's side. Can anyone help?
