Partly covered: Vauxhall published July 2014, February 2015 and August 2015 Mokka handbooks that could apply to a 2015 car, and their fuse charts differ. Vauxhall doesn’t say which cars each edition applies to, so we can’t tell which one matches a particular 2015 Mokka. Every official chart is shown below — check the edition printed near the end of your handbook, or compare with the fuse box legend in your car, before removing anything.

How to replace the fuse safely
- Switch off the ignition and all electrical equipment. Take the key out, or move a keyless fob away from the car.
- Open the fuse box and find the fuse using the number on the cover legend or the chart on this page.
- Pull the fuse straight out with the plastic fuse puller (usually clipped inside the fuse box) or fine-nose pliers.
- Look at the metal strip inside the fuse. A broken or burnt strip means it has blown.
- Fit a new fuse with exactly the same amperage rating. The number on top and the colour should match.
- Refit the cover, switch on and test the component.
- Never fit a fuse with a higher amperage rating than specified. It can let wiring overheat.
- Never bridge a fuse with wire, foil or anything else.
Fuse keeps blowing?
A fuse that blows again straight away is doing its job. Something on that circuit is drawing too much current. Common causes are damaged wiring shorting to the bodywork, a failing motor or socket, water getting in, or a faulty accessory. Fitting fuse after fuse, or a bigger fuse, won’t fix the fault and can overheat the wiring. Have the circuit tested by an auto electrician.
Not the fuse? Check these next.
Vauxhall-fitted or aftermarket
These fuses cover the circuits Vauxhall labels in its handbook. An aftermarket towbar kit may have its own separate fuse.
Trailer socket and plug
Corroded pins in the towbar socket or trailer plug are a common cause. Clean and check them.
