You will see an “n” word (for plastic fuse) or a metal link in a good fuse. It can be seen clearly with lights from behind the fuse. For blown fuse, the metal link will be separated just like the picture shown above. If you no longer see the “n” word like metal link, the fuse is blown.

Step 4: Replace the fuse

Bring the fuse and go to any car accessories shop to get the same fuse. Purchase the exact Amp, if the shop is out of stock, try another shop. Do not purchase a lower Amp fuse or higher Amp fuse. For example, if the fuse blown is 15 Amps, buy a new 15 Amps fuse. If you replace with 5 Amps fuse, the fuse will blow sooner than it needs to, which is not good. If you replace with 25 Amps fuse, it will not blow when it needs to and could bring possible damage to the part of your car, which is bad! Also, do not bypass fuse in your car which could bring possible damage and the damage could be costly! After you get the new replacement, you can simply push the fuse into the fuse box using hand easily. That’s the simple four steps on how to replace a blown fuse in your car.
