Opel Mokka X 2017 has three main fuse-box locations: engine compartment, dashboard and luggage compartment. Each has independent numbering groups for miniature blade fuses and the larger J or S/B protection, which must not be mixed. This facelift configuration is based on the factory 2017 model-year owner handbook (August 2016), including all 15 marked relay sockets.
All 131 source entries in 9 complete tables are preserved, including empty positions. The 116 fuse positions and 15 relay positions are kept separate. The 3 original diagrams are retained. The source does not provide universal current ratings, so unverified amperages remain “-” instead of guessed values.
Where are the fuse boxes?
Switch off the ignition before access. The engine fuse and power distribution housing is under the bonnet next to the battery; release the lid clips and lift the cover. The passenger compartment fuse unit is beneath the driver’s side dashboard behind its access panel. The luggage compartment holder is behind the left side trim. Right-hand-drive Vauxhall versions can have different access trim. Check the actual fuse-cover legend and equipment before replacing a fuse.

Fuse box FAQ
Which fuse is for the cigarette lighter?
The documented front 12 V socket is at dashboard mini fuse 22. The rear centre-console socket has its own fuse 23. Check the factory fuse-current rating in the installed car.
Where is the fuel pump fuse?
Under-bonnet mini fuse 19 in the documented arrangement.
Are Mokka and Mokka X fuses identical?
No. Compare the separate Mokka 2013-2015, Mokka 2016 pre-facelift and Mokka X 2017 guides. Differences include J3/J4/J7, cabin accessories and relay sockets. Never apply another year or generation’s current rating without checking the correct manufacturer reference.
Only fit the specified fuse type and rating; repeated failures require electrical diagnosis.
