Fuses are designed to blow if they detect too much voltage in your car’s electrical circuit. The only way to fix a blown car fuse is to install a new fuse.
Replacing a blown fuse can be tricky, so make sure you know what you’re doing before proceeding. Always get a professional’s help if you’re unsure of what to do.
Here’s what to do to replace a blown fuse:
  • Locate your car’s fuse box and remove the cover
  • Identify the broken fuse
  • Remove the blown fuse with your fingers or pliers
  • Insert the new fuse in the same spot you removed the blown fuse
  • Re-cover the fuse box
  • Start your car to see if the electrical components are working again
