2021 Mazda CX-5 Fuses and Fuse Box | How to change fuse
A dependable and necessary fuse box system is included with the 2021 Mazda CX-5 to safeguard its electrical circuits. This system includes two main fuse box locations, which are usually located within the cabin and in the engine compartment, providing complete coverage. Different kinds of fuses, such as blade-type and tiny blade-type fuses, are used in these fuse boxes to protect particular electrical circuits against overloads and short circuits. These fuses are essential safety devices that stop the flow of electricity when it’s needed to avoid harm and guarantee the proper operation of the car’s electrical systems. Maintaining and diagnosing electrical faults in the popular and adaptable 2021 Mazda CX-5 SUV requires an understanding of the location and function of fuses and fuse boxes.

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. Consult 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.
- CAUTION
- 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.
- 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. - Reinstall the cover and make sure that it is securely installed.

FAQs
The fuse box serves as a protective component, housing electrical fuses that safeguard various electrical circuits in the vehicle from overloads or short circuits.
There are typically two main fuse box locations: one in the engine compartment and another inside the interior cabin.
The fuse box contains different types of fuses, including blade-type fuses and mini blade-type fuses, each designed for specific functions.
Fuses act as safety devices, interrupting the electrical flow when an overload or short circuit occurs to prevent damage to electrical components.
A blown fuse can be identified by a visible break or burnt-out filament inside the fuse. A healthy fuse should have a continuous filament.
It is not recommended to replace a blown fuse with one of a higher amperage rating, as this can lead to electrical system damage or even a fire.
Some CX-5 models may include spare fuses stored within the fuse box or in a designated location.
The interior fuse box is often located inside the cabin, beneath the dashboard on the driver’s side, for easy access.
Regularly inspect the fuses if you encounter electrical issues or as part of your routine vehicle maintenance. It’s a good practice to keep them in optimal condition.
The CX-5 typically uses fuses rather than circuit breakers. Fuses are replaced when blown, and there’s no need to reset them.
While aftermarket fuses may be compatible, it’s recommended to use genuine or high-quality replacement fuses that match the specifications to ensure proper protection.
If a newly replaced fuse continues to blow, it may indicate an underlying electrical issue. In such cases, it’s best to consult a professional technician for diagnosis and repair.
To access the engine compartment fuse box, simply open the vehicle’s hood and locate the fuse box cover. Remove the cover to access the fuses.
