Just started working on my 91 Rover. Cant get Drivers seat to operate. Looks to be no power at switch, so no power at motor as well. Checked fuses in the dash beside radio all good even checked those under drivers seat they are all good as well. Which fuse is for the seats? Passenger seat works fine. A fuse diagram or legend would be wonderful if anyone can provide. Anyway any ideas? is there a common fault? I did notice two in-line diodes under the seat what are they for?
