Reasons Behind Aluminium Fuse Failure in Your Mercedes Benz

Mercedes Benz Aluminium Fuse

Keeping your Mercedes routinely maintained is essential to preventing issues such as aluminum fuse failure. This, unfortunately, is one of the most common problems that arise in Mercedes-Benz vehicles and one that has an increasingly high risk of occurring as the vehicle ages.

Aluminum Fuse Function

The fuse is a device that protects your vehicle’s electrical components and wiring in case of a fault. Possible faults include a positive voltage shorting to ground or a damaged component. When a fault occurs, the power that is being supplied to the component must immediately be disconnected, since this is one of the most common causes behind automotive fires.

To protect against such accidents, circuit breakers are incorporated into every single component that comprises your vehicle, many of them housed in one or two central locations called the fuse box. Some vehicles have several fuse boxes in various locations within the vehicle body, but it is most common to have them centralized in as few spaces as possible.

Signs of Failure of the Aluminum Fuse

Because the aluminum fuse is responsible for the regulation of electrical components in your vehicle, some of the first things you’ll notice in the event of its failure are the lack of functionality or reduced efficiency of certain vehicle features. This can manifest in a lack of power being delivered to your windshield wipers, automatic locks, windows, radio, or doors.

As soon as you begin to notice such symptoms, it is imperative that you get your Mercedes looked at by a professional as soon as possible, as these issues can become very dangerous, especially in the case of malfunctioning locks.

Reasons Behind Aluminum Fuse Failure

One of the major reasons behind aluminum fuse failure in Mercedes vehicles is corrosion. When the aluminum and copper parts are in close proximity to one another for an extended period, they exacerbate the potential for one another to fail. This possibility is enhanced by external elements, such as heat and moisture from condensation buildup. The tip of the fuse, the part that transmits power to all pieces connected, begins to corrode in such an environment and eventually becomes useless. The longer the fuse is exposed to such conditions, the worse these effects will be. This is why it is more common to see this failure in older vehicles.

Of course, apart from this, failure of the aluminum fuse may stem from manufacturing issues as well. Such a fault can be made worse by risky driving behaviors, but don’t feel singled out. It is common for owners of high-performance vehicles to push their engines to the limit of its engineering. After all, that’s part of the reason you chose it. Still, when harsh driving conditions and habits are paired with irregular maintenance, this can spell disaster, especially for a component that is not readily observed by the driver.

How to Prevent Aluminum Fuse Failure

Unfortunately, there is not much to be done on the driver’s part that can reliably prevent the failure of the aluminum fuse. In reality, it all comes down to the efficiency of the engineering that went into the construction of the vehicle, and its age. Unless you keep your Mercedes in a closed garage, under a car cover, and around 70 degrees at all times, the aluminum fuse will inevitably be exposed to environmental conditions that are less than ideal. Its use over time will result in some type of wear that will contribute to its eventual failure.

Luckily, the aluminum fuse is not a terribly complex component to be replaced, though it is never suggested that you undertake such a task alone. Any electrical problem with your vehicle must be diagnosed and solved by a trusted repair shop which is able to get the job done correctly without further damaging the electrical components of your vehicle.
