Hello,

I have a 1996 Jaguar Vanden Plas with three seat switch units that permit the seat to move forward and backward.

1) Drivers seat side switch down to the left and housed into the seat bottom
2) Passenger seat side switch down to the right and housed into the seat bottom
3) Items 1 and 2 have the same type of seat switch, just opposite sides
4) In addition, my passenger left arm rest has an extra switch (seems to be designed to be accessible to someone in the back seat).

All seat switches previously worked. All of a sudden, none of these three switches work. i.e. no forward backward seat movement.

My first thought goes to some common fuse.

Ideas?

Thanks,
Steve

Check the associated fuse to the power seats.

I had the same issue with our XJ300. I lifted the seats after removing the mounting bolts in the floor, and swapped the control units from the left to te right, and vice-versa. The seats both now work, albeit without the "memory" function. I'm not so lazy to need to adjust manually with my wife's positions.
I hope that works for you, too
