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

First of all, it is important to know what role the fuse box plays on a Chevrolet Impala.find-the-fuse-box-chevrolet-impala

Role of a fuse box on your Chevrolet Impala:

This fuses box is mainly used to protect electrical circuits that are crucial parts of your Chevrolet Impala.
It consists of a lead wire that is linked 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.

Because of this, the power is cut off and the peripheral parts are maintained, but above all it avoids 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 Chevrolet Impala

With developments 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 unaffected, 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 Chevrolet Impala.

Where can i find the fuse box on my Chevrolet Impala:

Now that you know its usage, you perhaps wonder where is the fuse box located in your Chevrolet Impala ?
In these modern times, the vast majority of cars have 2 cases and it’s not always easy to find them.
The ideal solution remains for you to consult the logbook of your Chevrolet Impala.

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

First, one of the boxes is often close to the driver’s side. It is sometimes hard to access and you may need to remove some protections from the inside of your Chevrolet Impala in order to reach it.

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

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

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

Different fuse models on your Chevrolet Impala:

Another crucial point to know when you are about to change 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. On the negative aspect, they have a limited resistance capacity, it does not correspond to the protection of any circuit of your Chevrolet Impala.
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 essential rules to follow to ensure the proper functioning of your Chevrolet Impala.

It is essential to change 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 Chevrolet Impala’s maintenance manual for the appropriate size. Each caliber often has its own colour, which will make it easier for you to recognize it.
You may possibly 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 Chevrolet Impala 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 !
