No need to be a DIY expert to replace fuses on a Toyota RAV4. This still requires some specific concepts and information, which is why we propose to help you through this article.

First, it is important to know what role the fuse box plays on a Toyota RAV4.find-the-fuse-box-toyota-rav4

Role of a fuse box on your Toyota RAV4:

This fuses box is mainly used to protect electrical circuits that are crucial parts of your Toyota RAV4.
It is composed of a lead wire that is connected to the input circuit of the electrical circuit. Because of its technical properties, lead heats up relatively quickly when the current flows. This allows it to melt if a possible overload occurs.

Consequently, the power is cut off and the peripheral parts are maintained, but above all it stops an overheating or even an explosion of selected sensitive parts, batteries for example. It is important to understand that this is an important part of your Toyota RAV4

With advances in mechanics and technology, it has been assigned other ancillary tasks over time, such as helping other electrical components, or even becoming a centralizing control box.

This means that even if its primary function remains unchanged, these additional tasks make its replacement a little more complicated.

We will detail in the next section how to locate the fuse box in your Toyota RAV4.

Where can i find the fuse box on my Toyota RAV4:

Now that you know its usage, you probably wonder where is the fuse box located in your Toyota RAV4 ?
Nowadays, the vast majority of cars have 2 cases and it’s not always easy to find them.
The best solution remains for you to consult the logbook of your Toyota RAV4.

If you don’t have this notebook, here are some advices to help you find your way around.

First, one of the boxes is generally close to the driver’s side. It is sometimes difficult to access and you may need to remove some protections from the inside of your Toyota RAV4 in order to reach it.

Another practical location is in the engine compartment. Look for the battery, it’s generally right next to it.

Once the box is located, you will need to find the fuse in question in order to be able to change the defective one. Indeed, on your case, each fuse corresponds to a specific role, you will have to find the matches. For example, your beam headlamps have their own fuse.
These assignments have to appear in your maintenance manual of your Toyota RAV4.

Be especially careful when removing it, you could damage the parts around it. Very often, a plastic clamp is provided with it, which will greatly facilitate your work.

Different fuse models on your Toyota RAV4:

Another crucial point to know when you are about to replace these parts is that there are different types of fuses. We will target here only on the most frequent models in order of size, from the smallest to the largest:

Mini fuses: They have a rating of 2 to 30 amperes. A significant advantage is that they are very small and as a result not very cumbersome. Disadvantage, they have a limited resistance capacity, it does not correspond to the protection of any circuit of your Toyota RAV4.
Standard fuses: They have a slightly higher rating than mini fuses (from 3.5 to 30 amperes) but are comparatively larger. They measure 2*2 CM.

Maximum fuses: These are the largest as their name suggests, they measure 3.5*2.5 CM, for an amperage of 30 to 90. Their role is mainly found on drive parts (cooling…)

Now that you have additional information about these famous fuses, all you have to do now is act cautiously.

Conclusion and other informations on fuse boxes

Here are also some important rules to follow to ensure the proper functioning of your Toyota RAV4.

It is vital to substitute a fuse with a fuse corresponding to the correct amperage. Do not rely automatically on the fuse in place, it may be there by mistake.
EX: There was a short circuit on a line because the fuse in question was too small. If you replace this fuse with its equivalent, the problem is very likely to happen again.

Please refer to your Toyota RAV4’s maintenance manual for the appropriate size. Each caliber often has its own colour, which will make it easier for you to identify it.
You might also wonder how to check if a fuse is blown and also if you can check it without removing it. The answer is yes.
You could easily visually inspect the element in a glass fuse to see if it has blown, but unfortunately they now mostly have solid, non-transparent bodies that hide the element from view. To know if the fuse is blown, you will have to use a multimeter. Once configured, a multimeter can measure the resistance of the fuse element. Resistance is measured in Ohms ‘Ω’.
You will find a tutorial for your Toyota RAV4 of this online by simply googling it.

Last but not least, be very careful with the surrounding electronic components, you could damage important parts when handling them or even more important harm yourself !
