Your vehicle's electrical system is complex, consisting of miles of electrical wiring. Thanks to the manufacturer's commitment to providing you with a safe and perfectly functioning wiring system, you rarely give that network a thought. The vehicle's fuse box, which protects the electrical system from power surges and electrical shorts, makes it easy to fix the occasional problem, such as your radio going out.

Step 1

Park the vehicle. Apply the parking brake.

Step 2

Identify the fuse panel. This is typically on the side of the driver's-side dashboard. It can also be located under the dash or under the vehicle's hood in the engine compartment. Refer to your vehicle owner's manual to determine where your fuse block is located.

Step 3

Check the fuse diagram. To locate the radio fuse, refer to the owner's manual or the diagram on the reverse side of the fuse block cover. There will typically be a drawing of the fuse block that identifies fuses by function and amperage rating (15, 20, 25 or 30 amp fuses).

Step 4

Remove the fuse. Use the fuse puller to grasp the fuse you suspect is blown--in this case, the radio fuse--and pull it straight out of the fuse block. If you do not have a fuse puller, you can substitute a pair of tweezers or needle-nose pliers or simply use your fingers. Check the fuse. If the small metal bar in the center of the fuse is burned through, you must replace it with a similar fuse of the same rating (color).

Step 5

Replace the fuse. Place a new fuse of the same color and amperage rating into the slot from which you removed the blown radio fuse. Turn the key to the accessory position and turn on your radio to verify that the problem has been resolved.

Step 6

Replace the fuse block cover, turn off the radio and turn the key to the "Off" position.
