Partly covered: Vauxhall published October 2019, January 2020 and July 2020 Corsa handbooks that could apply to a 2020 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 2020 Corsa. 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.

Which 2020 Corsa do you have?

The towbar fuse differs between versions of the 2020 Vauxhall Corsa. Until you choose, every possible result is shown.

Not sure which Corsa you have?
  • Vauxhall’s handbook prints separate fuse tables for electric and non-electric (petrol or diesel) cars: Corsa and Corsa electric.
  • An electric car has a charging socket instead of a fuel filler, and no exhaust.
  • Each Vauxhall owner’s manual prints its edition near the end, for example “Edition: September 2014”. If you have your car’s handbook, choose the option with the same edition.
  • Vauxhall doesn’t say which cars each edition applies to, so the date of your car alone can’t tell you. Without the handbook, compare the circuits on each option with the legend on your fuse box before removing anything.

If you can’t confirm it, keep both results in mind and check the fuse box legend before removing anything.

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.”

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.

  • 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.
