How to Replace a Blown Fuse in Your Vehicle

Visit Honest Car Dealer for helpful tips on replacing a blown fuse.

It might not happen often, but sometimes fuses in your car will blow. If an electric component in your car has stopped working suddenly and unexpectedly, then you probably simply need to replace the fuse. Fuses will blow when they receive a current that’s stronger than the component they’re protecting is designed to handle.  While it’s easy to replace a blown fuse, the electrical problem should be investigated and remedied by a professional to prevent more serious and expensive problems. However if you know what the problem is or just need a short-term stopgap fix you can easily replace a fuse yourself. Here are the steps to replace the fuses on your car:

  1. Make sure the car is all the way off and the key is out of the ignition. Pulling out fuses while electrical components are running is dangerous.
  2. Find the fuse box. The fuse box is almost always below and to the left of the steering wheel under the car’s dashboard. It should pop open easily without any tools.
  3.  On the back of the fuse box cover should be a map that tells you what each fuse controls. Look for the fuse that corresponds to the component that has stopped working.
  4. Find the blown fuse. While cars can come with several different kinds of fuses, you should be able to see that the blown fuse is different from a good fuse. The filament will be obviously melted or broken. If you can’t find a blown fuse, then your problem may lie elsewhere.
  5.  Pull the fuse out simply by pinching it and pulling it straight out with your fingers. No tools are needed.
  6. Sometimes cars come with extra fuses. If you already have an appropriate replacement then you’re in the clear! If not you’ll need to find a new fuse.
  7. Replace the fuse with an identical one. Fuses work at particular amperages and voltages and it’s important to match the original fuse exactly. This information is on the fuse and in your owner’s manual. Auto parts stores and service stations generally carry fuses.
  8. Replace the fuse by pushing the new one into the correct slot.
  9. Replace the cover on the fuse box and start the car to see if the problem has been fixed.
