1993 XJS power seat stuck in back position
The forward/back seat motor quit and the seat rail is in the almost full back position. I need to remove the seat to change out the motor, but I cannot access the two rear bolts that attach the seat rail to the floor because they are covered by the upper part of the seat rail. Please help!

Yes I did check the fuse first thing. It is the passenger seat. I ran 12V directly to the forward-back motor wires and got nothing. I then ran the test leads to the recline motor wires and also the bolster motor wires and both worked normally. I'm quite sure that the forward-back motor is no longer working and needs to be replaced.

In the Jag-lover's forum there are several messages in regard to the stuck XJS seat. Here is one link: https://forums.jag-lovers.com/t/xj-s...removal/327156. Go to the Jag-lover's forum. Type in xjs power seat motor removal.
I believe this will solve your dilemma.

Hi MHF25, I just checked it out, and my drive system (and probably yours) is different than that of a '92 XJS. The '92 has a long screw drive on each side of the seat rail and it does look like if you disconnect the forward end of the rod that it will move inward enough to disengage itself from the slots in the side of the seat rail. I believe that this would work perfectly on the '92 and possibly earlier models.
Our '93s are a different setup. There are two very short drive shafts that drive small 90 degree gearboxes, on each side of the inner seat rails. To complicate it even more, the outside shaft goes through a potentiometer that senses the position of the seat.

Did anyone figure the seat removal out? I have a '96 and the passenger seat needs to be removed. I can get at the front torx bolts but not the back. I can't see a way to get at them and all the bolts to remove the seat from the frame are inexcessible. Is there a way to slide the gears out of the way to slide the seat forward.
The only other thing I can think about is to try and use a reciprocating saw to cut the back bolts off, but I know its not going to be pretty. Help please.

Yes I did. On the '95-'96 cars you remove the two pins located on item 3 on the diagram. Remove the screw holding the small metal plate located at number 3, then pull the 3 inch shaft gears, 10ish star shape, Once removed you can push the seat forward and backwards. Mine required a sledge hammer to convince the seat to move. Once repaired the pins need to be placed back to hold the seat in place.
You then can figure out why it wasn't working. My was just seized and removing it and adjust the seat to be in alignment it worked fine.
I hope that helps.

It's under the foot well carpet just in front of the seat itself. You have to peel up the mat, carpet under it and black foam . The seat connectors plug into the box. The box harness has a ground wire nearby. Check for water sitting on floor, grounds etc. Unplug and plug the connectors back in and try. Swap boxes from left to right for troubleshooting assuming the driver's module is the same as the pax.
