Neff extractor fan not working

I have a similar problem with a Whirlpool oven hood. In my case the kitchen fiitters used a (UK) standard 3-pin plug to power the hood. The plug is fitted into a socket that is placed on top of the cupboards that house the hood.
I have replaced the 3 amp fuse in the plug and now the fan is working.
HOwever, the light isn't working and so I'm assuming that the bulb has blown and that this has caused the fuse to blow as well.
Now my problem is accessing the bulb so that I can replace it.
