How to change a car fuse: Steps to follow
Most cars have two fuse boxes – under the hood and close to the instrument panel near the dash. Most cars these days have around 40 or more auto fuses assembled in two or more places, and the amp rating varies from 10 to 30. Changing a fuse in your car is almost like changing a fuse at your home. So, follow these steps to know how to change a car fuse. You can avoid a visit to a repair shop and save your money!
1. Locate the fuse box
It is the primary and most important step on how to replace a fuse in a car. Mostly, you can find the car fuse box under the hood or near the dash. If you have any confusion, better check the owner’s manual. It will have the exact location of the automotive fuse box. Remove the panel cover once you find out the car fuse box.
2. Find out the broken fuse
You can locate many fuses in different colors once you remove the cover. The colors and numbers on the fuses represent different amperages. A diagram on the back of the cover will usually show each fuse’s amp rating. It is easy to find the broken fuse as it will have a broken filament or look black inside. Use a flashlight to locate it quickly.
3. Remove the broken fuse
The blown fuse can be removed by hand or using some tools. A car fuse puller or needle-nose plier is the best tool to remove a damaged fuse. Remember that it is harder to remove a broken fuse than a working one. So, be cautious if you’re trying to remove it by hand.
4. Replace with a new fuse
Be careful when you insert a new fuse into the fuse box. Do this step only after referring to the owner’s manual. Confirm that the replacement fuse is of the same amperage as the removed one. You can insert the new fuse in the spot of the removed one using your hands. Be aware that inserting a fuse of the wrong amperage will result in critical electrical issues.
5. Turn on the ignition
By this, you reach the final step on how to change a car fuse. Turn on the ignition and check whether the circuit that troubled you is working fine or not. If it is, you have successfully replaced a fuse in your car. But, if the new fuse blows as soon as you install it, understand that there are issues with the circuit. Then, quickly visit a mechanic or get an appointment with the dealer to solve the issue.
Can you drive with a blown fuse?
No. Never drive a car with a blown one. Replace with a new fuse quickly when you’ve got a blown one. If you don’t have the spare fuses or tools, visit a mechanic quickly and replace the blown fuse.

How can you tell if a fuse is good or bad?
You can always test a fuse using a multimeter without removing it from the automotive fuse box. Place the two multimeter leads on either end of a fuse. The fuse is good if the multimeter shows a 0-5 ohms reading, whereas a bad fuse will show a higher reading.
How much does it cost to change a fuse in a car?
It depends on the type of fuse used in your car and the power requirement. Normally, fuses cost between $10-20. But, in some cases, fuses can cost you more than $100, along with diagnostic costs.
How to change a car fuse: Some essential tips
- Realize that a car fuse has blown when electrical components stop working.
- While replacing the fuse, you can locate the fuse box under the hood or near the dash.
- The fuses come in different colors and numbers, representing their amp rating. A broken fuse will have a broken filament or look black inside.
- You can remove the blown fuse using your hand. Or use a car fuse removal tool like a car fuse puller or needle-nose plier to remove it. Use a multimeter to test a fuse without removing it from the box.
- Ensure that the replacement fuse has the same amperage as the removed one. Inserting a fuse with an incorrect amperage will cause serious electrical issues.
- You can get a bad fuse anytime. So, always keep spare fuses in your car’s glove box. Also, have a fuse puller tool in the car always. Also, when a fuse blows, ensure to check its circuit to find out the reason for the damage.
