The car’s fuse box is a necessary device that holds fuses, which are low-resistance resistor devices. If the current of your circuits exceeds what they can handle, then these “failsafe” mechanisms will blow to protect them from higher currents and surges in power.
Sometimes this system fails due to physical damage or electrical issues with the circuit; however, once you identify if there has been any change in behavior for your car’s electronics, after checking the condition of each fuse visually and testing each individual wire inside of the panel, if the fuses seem to be ok, then the whole fuse box might need replacement.
Just how much does it cost to replace a fuse box inside your car?
A fuse box can be as cheap as $5 or expensive as much as $400, but before deciding on an option CarParts.com recommends considering the design, installation, and material of your desired product to ensure it meets your needs accordingly.
If it is difficult for you to install yourself, then installation costs will add up by about anywhere between $65-$110 in labor fees if someone else has to do this for you at your auto shop or mechanic’s garage.
How do you replace a car fuse box?
During the repair, the battery will be detached and the fuse box will be identified. The majority of the fuse boxes you can find today are either located under the hood or underneath the dashboard, near the steering wheel. Inside the circuit box will be a large red wire, known as a battery supply wire. This cord will be unscrewed, and if other wires are around the box, these will be taken away too. By now, the fuse box can be wiggled free, the fuses will then be taken out and the new fuse box will be installed in its location. The work can take a mechanic about 90 mins from start to finish.
Any extra costs to consider?
Do-it-yourselfers may be required to use a fuse testing tool if they want to do the repair at home. The inexpensive, handy tools can also be bought from an auto parts store and are used for checking each individual fuse before it is replaced in its proper place. This tool shouldn’t be more than $5.
Any tips to remember?
Fuses come in different sizes, colors, and amperages so it is important that you get a new one with similar properties to make sure it will work properly inside your car. If a higher amp-sized fuse were added instead of replacing it with a similar amp-sized unit then wires could potentially melt due to too much power flowing through them which can lead to more serious complications like injury or fire risk from short-circuiting wiring components. If you were to try using lower amp units, the car might not start, because of not enough electricity reaching electronic components.
The best way to find your fuse box is by consulting the vehicle’s manual. The owner’s manual will provide both a description of every fuse as well as an electrical setup and the exact location of the box. If you don’t have that handy though, it may be worth trying to contact the manufacturer for assistance in locating and identifying it.
It can sometimes be difficult to yank out fuses from hard-to-reach areas so try using things such as plug pullers (which are often included) or tweezers if necessary.
When removing a fuse, first use one hand to pry open the end cap with either a standard screwdriver or pliers. This will help you avoid breaking it in half while trying to pull it out of its casing. The location of your particular car’s fuse box depends on what circuit is being protected by that specific electrical component; if not installed underneath the hood or dashboard, then most likely found in an easy-to-access compartment such as trunk space under insulation and metal panels for safety measures.
This type may be referred to as “remote inline” which are typically smaller fuses used for accessories that aren’t integrated into factory wiring – these can usually be accessed after tracing wires from the accessory to the fuse panel.
Before buying a fuse, it is important to take note that the cover for your car’s electrical panel often includes some spare fuses and sometimes even a tool. These items can be bought at auto parts stores or service stations.
Clearly mark each wire before removing them from their respective sockets so when you’re doing things in reverse to put all pieces back in place, putting everything back together will be much easier with less risk of error.
