I've got an '04 Zafira GSi and a couple of days ago one of the interior
light bulbs in the central pair stopped working. So I popped the cover off
thinking it was a blown bulb, but when I pulled it out the filament was
intact. So I put the bulb back in and it lit when fully depressed by my
finger, but when it popped back to it's normal position it went back out.

So, thinking it might be a dodgy connection I pushed the bulb back in
again upon which it lit up, and then all the interior lights went out,
including the glovebox...

'Blown the fuse' I thought, so I pulled the fuse only to find it intact.

So, before I start to really mess about with the car's electrics, any
suggestions as to what the problem could be?
