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.
Checking the relay
- With the ignition off, pull the relay straight out of its socket. Rock it gently if it is tight.
- Relays rarely look damaged when they fail. To test, swap in an identical relay with the same part number from a non-essential circuit.
- If the fault moves to the other circuit, replace the relay. If it doesn’t, the problem is elsewhere.
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.
Bulb
A blown bulb is the most common cause. Some cars have only one reversing light.
Reverse light switch
On manual cars, a switch on the gearbox turns the light on in reverse. It can fail or become unplugged.
