All, I'm trying to swap the seats and console over on my 94 XJS V12 convertible as they're slightly weathered due to a torn top. I cannot for the life of me get to the rear bolts. The front ones came out okay by moving the seat back, however the rear are impossible to get out with the seat moved as far forward as possible, I don't see an obstruction under the seat and both front seats extend forward to the same amount which still covers the rear portion of the seat frame.

Any clue as to what's needed here?

Thanks

 

The seat should move forward enough to expose those rear bolts. Something is preventing this from happening.

 

Checked, double checked and triple checked. The only thing stopping the seat moving forward is the motor which stops. Both seats stop dead at the same position.

 

You're trying to take out the bolts that hold the seat runners to the floor, Yes?

If so, the rear bolts are definitely exposed when the seat is moved forward to its maximum forward position. If that isn't happening, then there's either a problem with the motor or the switches within it that recognise movement limits or you've got something in the runners preventing the movement.

Do you know if the seats are definitely going forward to their maximum extension? Attached is a pic of the inside runner of the right hand seat, when in maximum forward position. I should be with my car tomorrow and if no other member can respond before then, I'll try and take a photo of the front part of the seat in the maximum forward position for you to compare.

Cheers

@ptjs1 - Correct, the front portion of the runners are exposed when the seat is moved back. The rear portion are not when the seat is moved all the way forward. Both seats stop at exactly same place when the seats are move forward. Even if I get behind the seat and push with my knee while operating the front seat switch, the seat only goes so far.

In searching threads, I see that other people have posted the same issue on this forum, but none followed through with a resolution.

 

I have a 1994 XJS Convertible as well and when the driver's seat is all the way forward the rear bolts are definitely exposed, and by a good amount.

 

Thanks, I'm not sure what's going on with mine. Both sides stop at exactly the same spot which is where the cushion back and the back of the seat rail are directly on top of each other. I'll have another go today.
By the way, nice other cars. I also have a 71 TR6, 72 280CE (d-jet with a 4 speed) and a Series 3 V12 :-)

 

The seat module only allows a certain amount of movement per push. Mine moved then stops. I release the switch and push it again and the seat moves more.

 

I'm not sure how true this is, but one forum member posted that the issue described by Jagboi64 is caused by deterioration of the sensors in the seat module. Apparently a problem also with x300 cars. My seats do full travel on one press of the switch. Or maybe mine are faulty?!!

You might want to first check that there's no obstruction in one of the runners preventing movement. If not perhaps, look through the wiring diagram. Then disconnect the seat plug and directly apply 12v to the appropriate plug terminals to see if you can force it to to perform full travel?

Thanks, mine stop in increments but only move so far forward. Both seats move to the exact most forward position.

 

I think I would try several different things.

- Maybe try a different switch?
- Like ptjsd1 suggested, try powering the seat directly with a 12 volt source.
- If the seat goes far enough forward could you get a Torx wrench in to loosen the mounting bolts?
