How To Replace an Electrical Fuse in a Car

Some really common car problems such as the radio not working are simply just due to a blown out car electrical fuse. Blown out fuses happen as a precautionary measure so as not to further damage the other electrical components of the car when there is too much electrical current running through the wires.

  1. Know when it is time to replace an electrical fuse in a car. Electrical problems are commonly brought about by busted electrical fuses in your car. If engine fan blades do not budge at all once you start the car, or the signal lights on the dashboard do not function at all, or the car horn just keeps on blaring without even touching it, then it's high time you check the electrical fuses of your car.
  2. Find the electrical fuse in your car. Most cars place the electrical fuses in a series of blocks or panels which is typically contained in a box. You will find these sets of electrical fuse blocks or panels right beside the column holding the steering wheel. Some makes and models of cars, on the other hand, have the electrical blocks or panels positioned within the engine's housing under the hood while others can be found right underneath the glove box.
  3. Know how to identify a blown out electrical fuse. Once you have located the electrical fuse in a car, then you will now need to confirm if the fuse is indeed busted. But before doing so, you have to turn off the car's engine first to avoid accidents. Open the fuse and check if the wires within it are popped open with wires burnt or blackened. If it is indeed blown out, then pop the fuse out of its respective slot using the supplied fuse remover. If you do not have this, you can just a screw driver to do the job.
  4. Buy the correct type of electrical fuse. Read up on your car's user's manual for the correct type of fuse to acquire from the hardware store. This is very important as the replacement fuse needs to have the same ampere and voltage ratings as the previous one. Newer models of cars, on the other hand, have color-coded fuses that resemble blades. All you need to do is remember the color of the blown out fuse - this will assist you in buying the right fuse. Better yet, just bring the blown out fuse with you when checking the stores.
  5. Install the new electrical fuse. With the correct fuse in hand, open the fuse box. Just slide the fuse into the respective slot where the blown out fuse was once positioned. Doing so should result in the fuse snapping into place.

With the replacement fuse properly installed, you can now start testing. Just start your car and check the electrical components that were previously damaged if they are already working. If not, then chances are some other problem is causing the electrical failures.
