Find the Fuse Box and Change a Fuse

The Mazda CX-5 Mk1 (KE, 2012–2017) has two fuse boxes: one in the cabin, behind a panel on the left-hand side of the dashboard, and one in the engine bay. If an electrical item stops working, a blown fuse is the first thing to check — and swapping one is a job you can do at the roadside.

Where the Fuse Boxes Are

• Cabin fuse box — behind a removable trim panel at the left end of the dashboard (driver’s side on LHD cars). Check this one first for interior circuits.
• Engine-bay fuse box — a covered box under the hood. The plastic fuse puller clips inside this box.

How to Find and Change a Blown Fuse

1. Switch the ignition and the affected accessory off before touching a fuse.
2. Open the correct box and read the legend on the lid to find the fuse for the circuit that has failed.
3. Pull the suspect fuse straight out with the fuse puller from the engine-bay box.
4. Hold it to the light: a blown fuse has a broken or melted metal strip inside.
5. Fit a new fuse of exactly the same amperage (printed on top and colour-coded) and push it in firmly.
6. If you have no spare, you can borrow one of the same rating from a non-essential circuit such as the audio or accessory outlet to get going.

Use a genuine Mazda or equivalent fuse of the identical rating — never a higher one, which can let wiring overheat.

Frequently Asked Questions

Where is the fuse box on a Mazda CX-5 (KE)?

There are two: one behind a panel at the left end of the dashboard, and one under the hood in the engine bay. The fuse puller lives in the engine-bay box.

The same fuse keeps blowing — what now?

A fuse that blows again points to a fault in that circuit. Stop using it and have the wiring or component checked rather than fitting fuse after fuse.

Can I replace the main fuse myself?

No. The high-amperage main fuse is a dealer item — if it has failed, have it done by a workshop.

If a warning light came on with the blown fuse, look up the stored code on autodtcs.com.
