Hi, I have just purchased a 2000 S Type 3ltr V6 and the drivers seat controls are not working. There is no sound from any of the controls so I guess it is a power supply issue or is there a known fault with this?
I have also noted that the electric door mirrors are not working so can they be connected as part of the same problem?

Thanks.

Mak.

Welcome to the forum, enjoy.
First question is, do you have memory or non memory seating?

 

[Mak]

Memory seating.

 

[Mak]

Thank you for the welcome. 😁

 

[JimboV8]

Memory seating.

Check fuse F21 30A in the rear distribution box and fuse F7 5A in the primary junction box.

Being really cheeky but do you have a fuse box location picture? Havent yet got/downloaded a manual. Appreciate your help as I am 6 foot 1 and the seat is adjusted for a small person so I am crippled trying to drive it.

Here is the electrical manual for your car; http://www.jagrepair.com/images/AutoRepairPhotos/x2001999.25en.pdf

You sir are a diamond in a bucket of coal. Thank you for your time and help. I can get it sorted now with that info.

Fuses all okay.
Noted that lumber support motor is working which I didnt check, oops. So looking at the wiring diagram therevare different motors for each action and none of them are working so do I suspect the control module? Do they commonly have issues or can it be wiring/connector issues?
Thanks for any advice.

Mak.

The next thing to do is locate the module, under the seat and disconnect the plugs going into it. Wait 2 minutes, reconnect and then try again. If it still doesn’t work after that then you either have a module problem or a wiring fault.

 

[Mak]

Is the module under the seat as the link you kindly sent shows it in the passenger side area?
Either way I will unplug it and see iff a reset works.
Thanks again for your time.

Not sure on your car Mak, only takes 2 seconds to look underneath though.

Drivers seat module is located under the seat, and works in conjunction with the Drivers door module, which, rather unsurprisingly, is located in the drivers door. (Also connects with other modules via the SCP network for memory setting/recall etc, but I doubt your issues will be anything to do with that)
Power for the seat adjustment motors is supplied to the seat module via a 30 amp fuse, # 21 in the rear distribution fuse box in the boot, and a 12v logic supply via a 5 amp fuse, # 7 in the primary junction fuse box in the drivers foot well. Power for the switch pack is via the same #7 5 amp fuse, and the lumbar support pump is supplied by the same 30 amp fuse # 21, but via a separate supply wire. If the lumbar pump is working, fuse #21 must be ok, so look at fuse #7, and if ok, check for 12 volts at pin #7, Orange/Yellow wire on the seat switch pack and also pin #10, Orange/White wire on the drivers seat module. If you have power going into the switch pack and seat module, and the motors still don't do anything, there's not much else except the seat module. Everything goes from switch to module to motor for basic adjustments. Individual motors can be tested by disconnecting at their appropriate plugs and feeding them 12 volt + and -. Doesn't matter which way round, as reversing polarity just reverses motor rotation, just make sure you get the motor power wires, not the memory position sense wires.

Hope this helps, let us know if you need anything more.

OW

Thank you for all this information and your time.
I will check all the above and let you know what the fault ended up being.
Cheers

Checked tonight after work, put my hand underneath the seat to find the control unit and cables and my hand got covered in oil so I guess that has come from the lumber support and leaked all over the electronics hence the seat not working.
Problem now is getting to the bolts to take the seat out and repair the electrics when you cant move it to get to the four bolts.

If you have a seat module under the passenger side you can swap them in order to move the seat.

Have you ever removed a seat module while the seat is in place before?
Any tips or tricks?
Thanks.

The only time I have needed to was on my XK8. The seat module was held on by 2 bolts at the front of the seat, the bolts just needed to be loosened and then the module can slide out. You then just disconnect the plugs and away you go.

When it stops blooming raining I will get under the seat and see what I can get to.
Thanks.

The X200 is a little different to the later models, in that the rear mounting bolts fit more horizontally, rather than vertically like the fronts (and rears on later models). If the seat is far enough back, you may be able to get access to the front bolts and remove them, then with any luck, the rears can be got at and loosened enough to allow the seat to tilt back with a longish extension and socket and bit of fiddling around. Access to the module will be very tight and difficult with the seat bolted down and unable to move backwards and forwards, and the output connectors are to the rear, so near impossible to get to to power the motor directly to move the seat.

This is a picture of the underside of an X202 seat, which from memory is similar to the X200. The modules etc are different, but it gives you an idea of the layout (Front is to the top).

Sorry, I don't have any pic's of the X200 seat, but this is the drivers seat from a LHD X200, minus the module, nicked off the internet, and it just about shows the rear mounting bracket with the bolt hole to give you an idea of the angle and where to find it (top left of picture)

I don't think there should be any oil in the lumbar support, as far as I know, it just operates on air pressure?
