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.
- 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
Fuses protect the vehicle’s electrical components by breaking the circuit if an excessive current flows, preventing damage or electrical fires.
The fuse box is usually located in the engine compartment or inside the vehicle. For more information on the specific location in the 2023 Mazda CX-5, consult the owner manual.
Look for a visible broken or melted wire inside the fuse. In some cases, the metal strip inside the fuse may become separated. A multimeter can also be used to determine continuity.
The Mazda CX-5 may use standard blade fuses. Replacement fuses are available at auto parts stores, and the owner’s manual includes information on the proper fuse ratings.
It is not recommended. Always replace a blown fuse with one with the same amp rating to ensure proper electrical system protection.
To remove the blown fuse, use the fuse puller tool or a pair of needle-nose pliers to gently pull it. Insert a new fuse with the same rating into the slot.
Refer to the owner’s manual for specific instructions on replacing fuses in the Mazda CX-5, as the procedure may differ depending on the model and fuse location.
If a fuse consistently blows, there could be an underlying electrical problem. Consult a professional mechanic or a Mazda service center to diagnose and resolve the issue.
Some vehicles are equipped with a spare fuse kit. Check the fuse box cover or the owner’s manual for information on spare fuses and where they are located.
While it is generally recommended to use OEM (original equipment manufacturer) fuses, reputable aftermarket fuses with the proper specifications can be used.
Depending on the model and trim, the Mazda CX-5 may have several fuse boxes. The owner’s manual describes their locations and the components they protect.
Checking and replacing blown fuses can sometimes fix problems with lights, power windows, or the audio system.
Yes, the fuse box cover or owner’s manual usually includes a diagram illustrating the function of each fuse and its corresponding component.
Yes, many fuse boxes have clear covers that allow you to visually inspect the fuses. However, if in doubt, remove the fuse for a more thorough examination.
Before attempting to replace a fuse, ensure that the vehicle has been turned off. To avoid damaging the fuses or causing injury, use the appropriate tools, such as a fuse puller. If you’re unsure, seek professional help.
