The power on your car is connected to a set of fuses that control everything from the stereo to the turn signal blinker. When a fuse burns out, it is a fairly simple process to replace, and it can be done by just about anyone. Here is a step-by-step guide on how to replace a fuse on your car.

To complete the following task you will need these items:

  • A replacement fuse that is the correct amperage
  • A pair of pliers
  • A screwdriver

1 - Make sure that the car is completely powered off and the keys are not in the ignition. Make sure that your car is not plugged in to any power source to avoid the potential for getting a shock.

2 - Locate the fuse box on your car. Most fuse boxes on newer models of cars are located under the hood of the car, and many older models of cars the fuse box is located under the dash. Once you locate the fuse box, remove the cover to the fuse box with a screwdriver.

3 – Identify the fuse that has burned out. If you have glass cylinder style fuses then you should be able to identify the burned fuses as there will be black burn marks inside the fuse to show where it burned out and the metal inside will be separated. In newer style fuses they will have a little display window where you can see the filaments burned through.

3 - Pull out the burned out fuse and replace it with a new one. If you can't just pull out the fuse with your hand, you might need a pair of pliers to pull it free. The new installment fuse should be able to be pressed into place until it clicks into place. Make sure that the replacement fuse is the correct amperage otherwise it will immediately blow when you reconnect the power or could potentially cause an electrical problem. If you don't know what amperage is correct, consult the owner's manual and confirm with a professional auto mechanic familiar with your make and model of vehicle.

4 – Put the cover back on the fuse box with the screwdriver. Once it's back in place, start the car to test the replacement fuse and make sure everything is back to working order.

If the steps outlined above do not fix the power issues in your vehicle, it could be a sign that you have a much larger electrical issue and you need to have it inspected by a professional mechanic like Vince's Auto Service. If you are not comfortable with replacing the fuse yourself, then the mechanic can also replace a fuse for you for a modest fee.
