i think there is a diagram on underside of ashtray mat,but if you take each blade fuse out in turn you will see the 2 blades and between each there should be a wire connecting them,this should be intact [if you have a multi-meter there should be continuity],if not then fuse has blown ,only replace with a fuse of same amperage/same colour.try each in turn noting any spaces that are not used and refit in same position. if fuse blows again then you have a short to earth on the same circuit! hope this helps.
