interior lights not working????

just bought a 2001 Disco SE and the interior lights are not working. The dash, radio, lighter all work fine, its just the the three dome lights (Front, back seat & rear)...Checked fuses under steering wheel and under the hood and they are all fine. Any other fuse locations? and yes I checked and replaced all three bulbs.

The cause of the interior lights not working was caused by a Corroded Header Junction. Had it replaced and everything is working like new.

where is the header junction? Did you do it yourself? If you had someone else do it how much did it cost you?

Ping,
I had the Land Rover dealer fix it, I still have one year warranty left on my Disco so it was free, but I think its behind the glove box. If I ever have to go back anytime soon I will ask them where its located.
