Seat doesn't move forward or back nor tilt forward back. If I have to replace the front seat control switch my Bentley manual states that I have to remove the entire seat. However, in order to remove seat you need to remove seat mounting bolts but because I can't move seat forward or back I cannot get to the rear mounting bolts. Does anyone know if front seat control switch can be replaced without removing seat? Or, how can I remove front seat if I seat is sitting right on top of rear mounting bolts; i.e. how to manually move seat to access bolts? Any and/or all advice appreciated. Thanks!
