Always replace blown fuses with properly rated fuses according to the vehicle owner's manual. The first response to non-working electrical devises is to check for a possible blown fuse. Read the vehicle owner's manual to find the fuse panel or panels. Some fuse panels will have a removable cover, spare fuses, a fuse-puller, and a handy circuit identification chart. Use the owner's manual or circuit identification chart to locate the suspected fuse and determine it's proper amperage rating.
Fuses are easy to remove and replace as they just press into the fuse panel.
