Fuses and Fuse box
Fuses
- Your vehicle’s electrical system is protected by fuses.
- If any lights, accessories, or controls do not work, inspect the appropriate circuit protector. If a fuse has blown, the inside element will be melted.
- If the same fuse blows again, avoid using that system and consult an Authorized Mazda Dealer as soon as possible.
Fuse Replacement
Replacing the fuses on the vehicle’s left side
If the electrical system does not work, first inspect the fuses on the vehicle’s left side.
- Make sure the ignition is switched off, and other switches are off.
- Open the fuse panel cover.
- Pull the fuse straight out with the fuse puller provided on the fuse block located in the engine compartment.
- Inspect the fuse and replace it if it is blown.
- Insert a new fuse of the same amperage rating, and make sure it fits tightly. If it does not fit tightly, have an expert install it. We recommend an Authorized Mazda Dealer.
If you have no spare fuses, borrow one of the same rating from a circuit not essential to vehicle operation, such as the AUDIO or OUTLET circuit.
CAUTION Always replace a fuse with a genuine Mazda fuse or equivalent of the same rating.
Otherwise you may damage the electric system.
- Reinstall the cover and make sure that it is securely installed.
Replacing the fuses under the hood
If the headlights or other electrical components do not work and the fuses in the cabin are normal, inspect the fuse block under the hood. If a fuse is blown, it must be replaced. Follow these steps:
- Make sure the ignition is switched off, and other switches are off.
- Remove the fuse block cover.
NOTE
If the lock is forcefully opened, the fuse block cover may come in contact with the frame when it is removed and become scratched.
When removing the cover, remove it slowly according to the following procedure.
- Disengage the rear lock by pressing down on the front tab with your fingers.
- Remove the front tab while slightly lifting the front of the cover.
- Remove the cover while lifting it and sliding it to the rear.
- If any fuse but the MAIN fuse is blown, replace it with a new one of the same amperage rating.WARNING Do not replace the main fuse by yourself. Have an Authorized Mazda Dealer perform the replacement: Replacing the fuse by yourself is dangerous because the MAIN fuse is a high current fuse. Incorrect replacement could cause an electrical shock or a short circuit resulting in a fire.
- If any fuse but the MAIN fuse is blown, replace it with a new one of the same amperage rating.
- Reinstall the cover and make sure that it is securely installed.

The fuse box contains a network of fuses that protect the vehicle’s electrical components from damage caused by electrical faults or overcurrents.
The fuse box is usually found in the engine compartment or inside the vehicle, frequently near the driver’s side footwell. For more information on the exact location, consult your owner manual.
Check the fuse box for the appropriate fuse for that component. A blown fuse could be the cause.
Check the fuse visually; a broken or melted metal strip inside indicates a blown fuse. A multimeter can also be used to perform more accurate tests.
Yes, replacing a fuse is usually a simple process. Identify the blown fuse, then remove it and replace it with a new fuse of the same amperage.
To replace a fuse in your Mazda MX-5 Miata RF, you’ll need a fuse puller or needle-nose pliers, as well as the appropriate amperage fuses.
Auto parts stores, dealerships, and online retailers typically stock replacement fuses.
Yes, using a higher amperage fuse can cause damage to the electrical system. Always replace at the recommended amperage.
There could be an underlying electrical issue. If your fuses continue to blow frequently, consult a professional mechanic.
Some vehicles store spare fuses in the fuse box or a separate compartment. Check your owner’s manual for more information.
While most blown fuses affect specific components, a critical fuse failure can disrupt overall vehicle operation.
Is it advisable to modify the fuse box or electrical system in any way
Turn off the vehicle and wear gloves and safety glasses. Handle fuses with caution and never bypass them.
