Where is the Door Warning Lightsd Control module!?

[GSB1]

Hi,

I have an electrical fault which means neither or my interior footwell lights work, neither do I get a display on my DIS of what door is open etc.

I have an electrical disgram which shows both rely on the "Door Warning Lights Control Module".

However, I do not know where this is or what it looks like. Is it a plug in and out (ie easily replaceable) relay type unit?

Can anyone help?

Thanks
Graham
