How to change a Blown Fuse

blown car fuse

Here are some typical car fuses, also referred to as ‘spade’ or ‘blade’ type fuses because of their shape.  The different colours denote different fuse ratings i.e. red are 10amp and yellow are 20amp.

The amp rating is also normally stamped on the fuse too, so you don’t need to know what the colours mean.

Changing the fuse on a car electrical system is pretty easy, the ‘blade fuses’ just push in and out of the fusebox (see below).

You may need to check or change your fuses if something electrical on your car is not working, for example ;

– windscreen wipers have stopped working,
– electric windows have stopped working.


Before you even think about taking the car to the garage or stripping bits off your vehicle, find out where your fuse box is and check the fuses. Your Haynes Manual should tell you where the fuse box is located.

Where is the fusebox and what does it look like?
Most car fuseboxes will be somewhere under the dashboard of your motor. Some are on the drivers side around or under the steering column.  Some are on the passenger side under, in or around the glovebox or storage area.

What does a blown fuse look like ?

Good fuse - not blown Fuse blown

On the left is the good fuse, look in the middle and you can see it is still intact.
Look at the fuse on the right, and you can see in the middle that the fuse link is broken (it has blown).

So if you have an electrical item on your car that is not working, such as the radio or windscreen wipers, you need to look in the fusebox for a fuse that looks like the one on the right.  Replacing that fuse should get rid of the problem.  Always carry spare fuses in the car, they are very cheap.


If the same fuse continues to blow, either immediately or after a while, then this will require further investigation.  The fuse is probably continually blowing because of an electrical fault elsewhere on the car and this will need to be checked out by an expert.
