Checking and Replacing Fuses As we know, fuses protect the electrical systems of our cars from overload. When a component stops working, it is probably a circuit breaker or a blown fuse. Therefore, before repairing a component, check the fuse that is responsible for that component. A blown fuse will indicate a melted or completely broken wire inside the fuse.
Keep this in mind before replacing the fuse!
- remove the key from the ignition
- check if everything is turned off
- always replace fuses with the same amperage.
