Remove all of the bulbs from the back and then install a new fuse, if your fuse blows you have a short in the wiring somewhere or a socket that is very corroded. Your bulbs should be fine they should blow before your fuse does, if the fuse doesn't blow with all the bulbs removed you have a bad bulb or someone installed one or more bulbs with too high of wattage rating.
Check your shop manual for what wattage of bulbs you should have installed for the various bulbs.
