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!

Have you check the seat fuses? You didn't mention if the seat was the driver or passenger. Their fuses are in the under-dash L/R fuse boxes.

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.

This might help in viewing what is under the seat..

This problem really has me stumped!
I am wondering what a technician at a Jaguar dealership would have done if an XJS like mine came in for repair with this same problem during the warranty period!

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.

93 XJS coupe

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.

Just wondered if you ever got the bolts out? My drivers seat is stuck in the far forward position which doesn't work for my 6'6ish body very well lol!

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.

Awesome! I know what Im doing tomorrow, as well as trying to get my alternator pivot bolt unstuck! Thanks!

Just to ask, and Im guessing it will be fairly obvious when I look tomorrow, but can you just use pliers to remove the pins? Is it just on the right side at #3 or the left side also. Sorry just want to have a good idea for tomorrow

Just got done! I still didn't see the "pins" until I undid the torq boltand pulled the first one out and I was like "oh duh!" I gave it a couple good smacks and it went back! I still plan on pulling the seat, but I finally know that I should be able to drive it! Yay!

Hello I have a 94 xjs convertible And the passenger seat does not move . I used your method to adjust it, but was wondering if you know where there is a relay for it. I think mine might be bad? The switch is defiantly good . And none of the functions work . The seat just doesn't move , doesn't even try? When I push the buttons there is nothing , no click , no noise , nothing? It looks there is a separate motor for each function and I find it hard to believe that all 3 would go bad at once so that's why I'm thinking that if all the power comes through one relay to the seat than that would likely be the problem? Just don't have any idea where it is? Any body know where it is and if my thinking is correct about what is going on?

XJS power seat circuit
 

Sorry, I don't know if there are any relays in the power seat circuit. There are definitely common blade fuses, and they are located under the steering column and the glove box.
Does anyone else know if there are any relays?

Thank You! So I'm guessing that the "passenger seat control module" would be the culprit ? Any idea where that is? I had the seat out but couldn't figure out how to unplug it?

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.

Awesome! I won't be able to work on it prob till the weekend , I will let you know, thanks again!
