Yes they were part of the winter pack that also gave you heated mirrors.
As far as I know that's not the case.My car has heated seats and so I guess this should mean that there is the winter pack.
I presume they would have been available for both the older and newer types.
Edit: I've just had a look in ElsaWin and can't find the wiring diagrams for either of the Winter Pack options. Has anyone else found this?
I found the details for the heated jets, both are fed from fuse 33, details are in the attached files.

Excellent! Thanks Steve; I've now found it in ElsaWin.
Dan; the washer jets are heated as soon as you turn on the ignition. They are in no way tied to the demist button on the CC panel.
Cheers,
