Interior light doesnt work

And the vehicle is?

Opps, its a Discovery 300 tdi

I have exactly the same problem on the same type vehicle. As yet I have been unable to find the fault.

Simon,

The mfu is behind the fuse box on the driver side.The wire is purple and white, but, its encased in a protective black sleeve. I removed the fuse unit screws (2) and moved the fuse unit out of the way and then gave the protective sleeve a tug and the wire came out. I then put a new wire through a hole that is about 3/4 inch above and 1 inch back from the door switch that goes directly through to under the dashboard and joined it to the old wire. It's a bit of a fiddle, but got there in the end.

A word of warning! While I was undoing the fuse unit I think I must have shorted something (stupid I know, but, I didnt disconnect the battery) problem is now the lights on indicator and low fuel indicator dont work. It may be coincidence, but somehow I dont think so, I'll let you know what happens!

Thanks for you the advice Dave I will have a look at the weekend
