Citroen XM Forum

That's a good idea, I'll have a go at the motor before doing anything else. I suppose it could have just seized from being stood 8 years.

Apparently there was a pin position change from early S2 units and later units making them non directly interchangeable even though they look the same.

Xm exclusive posted this information up some years ago.. I remember reading about it. When the actual change happened I'm not certain of.

They both have 9 pins but the later plug has a red locking lever that engages with 4 round pegs on the socket.

I'll have another trawl through the older posts if needed, thank you.

In answer to my own question - apparently the pins / wiring are identical and either plug can be forced together.

Another possible solution if the motor doesn't come back to life.

Hi Andre

I am afraid you need to research quite a bit more to be part specific.
Very important to get right if parts have to be posted to NZ.
Series 2 XM drivers side window regulators varied with model and age.

The low spec cars used the same drivers door regulators as Mk 1 cars.
The one touch switch motor control was provided by a small ECU screwed to the back of the door trim.

The higher spec cars (VSX & Exclusive) were fitted with the ECU (one touch & anti-pinch) built into the winder motor.
These assemblies had a high failure rate and were expensive from Citroen (£200+) so much demand for second hand items.
These assemblies had 9 wire connectors so the door wiring loom was unique to the assembly.

About 1996 Citroen made this much worse by changing the plug/socket type for the winder/loom connection.
Early ones have a thin box shaped metal locking clip, later ones a big red plastic PSA slide locking clip.
The importance of this difference is not well understood as pins and wiring are identical and either type can be forced together.
All works on test but there is now no locking to the connection just contact friction.
The plug hangs down under the motor and with wiring weight, time and vibration the connection falls apart.

Also note that all XM window winders are door specific so LHD parts will not fit RHD cars.
So in this case second hand spares from France will not fit UK cars.
Over here dealers clear out of old stock parts happened some years ago so sourcing new is not an option.
Get us enough information to be certain what is needed then we can see if good second hand parts can be found.
Alternatively we may be able to suggest work around options.

The gift that keeps on giving!

More rust to be cut out ready for welding but I can see the light at the end of the tunnel now. Fuel pipes are a bit crusty so need cleaning up and a coat paint.

Front wing requires a piece letting in as well.

Those later, series 2 do seem to know how to rust, at least the fuel pipes are sound enough.

How does moisture even get in to those areas? I thought it was maybe related to the sunroof but can't be on this car!

The bottom of the front wings and sill area is due to dirt being thrown up by the front wheels compacting behind the arch liner, then being kept nicely wet due to the scuttle drains exiting into that area.
