Yes there is a switch which might have been wedged in the off position. From memory it's on the right hand side of the glovebox but if you look around the edge of the glovebox with the door open you'll see it.
There is a plug for the light unit which behind the glovebox which might have become loose, you'll need to remove the glovebox to get to it though which is aremarkably involved job...
One other thing to check would be the fuse, the manual will tell you which one is it - though as it will have other circuits or lights on the same fuse so if those work you can rule that out.
