Mazda CX-3: Fuses / 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.
- 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.
