Octavia Mk1 interior light not working but everything else is?

Hi

I just bought an Octavia L&K PD130 last week. It has a couple of issues but this one puzzles me. Ive read a lot of posts about the microswitches and the interior light but they all seem to include the door light not working.

My issue is that the glovebox, boot and interior light dont work when the door is opened. Everything else works fine. I was thinking it could be a problem with the actual switch (on the roof), or maybe a fuse?

If its a microswitch in the lock problem, then is it all controlled by the driver door lock?

Many thanks

Chris
