Have a corsa b R reg. The instrument panel lights have gone - not sure which fuse it is or just failure of bulb/bulbs. Can someone tell me which fuse it is, the fuse box does not seem to tell you which fuse is which and just to iron out the problem, if the bulbs have blown is anything else on the same curcuit that should have blown? also how do I get to the bulbs. Have taken out the 3 x head screws that hold the instrument cowling front off but cant seem to find how to get the back section off - thanks
