Step 1
Determine what fuses your car needs. There are two types: blade or glass tube. Newer cars use the blade fuse, but some older models, cars manufactured before 1980, may still have glass tubes. Find your car's fuse type in the owner's manual.

Step 2
Purchase fuses for your car at your local auto supply store. There are a variety of fuse sizes for the different electrical systems in your car. Buy the fuses that correspond to what is causing the trouble.

Step 3
Locate your car's fuse box. Most cars have one fuse box located under the dashboard. Some automakers install a second fuse box under the hood. It's easy to find and is usually clearly marked with a diagram that shows which fuses operate which systems.

Step 4
Remove the plastic cover from the fuse box. Turn the cover over to find the fuse diagram.

Step 5
Use the diagram on the inside of the cover to find the suspect fuse. This will depend on where you've lost electricity.

Pull the blown fuse out of its socket and replace it with a new fuse.
