Partly covered: Vauxhall’s February 2023 and September 2023 Corsa handbooks print no fuse chart (a defective fuse must be replaced by a workshop). The chart below is from the July 2022 edition and applies only to cars that came with that handbook.

Vauxhall’s handbook doesn’t print fuse ratings, so none is shown. Fit a replacement with the same rating as the fuse you remove — the handbook says: “Data on the replacement fuse must match the data on the defective fuse.”

    Position not shown on the schematic. Find fuse 4 on the fuse box legend.

Always confirm the number against the legend on the fuse box cover before pulling anything.

How to replace the fuse safely

  1. Switch off the ignition and all electrical equipment. Take the key out, or move a keyless fob away from the car.
  2. Open the fuse box and find the fuse using the number on the cover legend or the chart on this page.
  3. Pull the fuse straight out with the plastic fuse puller (usually clipped inside the fuse box) or fine-nose pliers.
  4. Look at the metal strip inside the fuse. A broken or burnt strip means it has blown.
  5. Fit a new fuse with exactly the same amperage rating. The number on top and the colour should match.
  6. 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.

  • Horn unit itself

    Horns sit at the front of the car, exposed to water and road salt. A corroded horn or connector is a common cause.

  • Steering wheel contact

    The horn pad connects through a contact inside the steering wheel. If the horn works only at some wheel positions, that contact may be worn.

  • Shared fuse

    If other items on the same fuse have also stopped, suspect the fuse or its supply rather than the horn.
