When owning a luxury vehicle like the Mercedes E Class, even small issues such as problems with the cigarette lighter can be concerning. The cigarette lighter, although seemingly minor, plays a significant role in powering various devices, including chargers and GPS units. If you’re experiencing issues with the cigarette lighter, the fuse is often the culprit. Here, we delve into understanding and resolving the mercedes e class cigarette lighter fuse issue efficiently and effectively.
Identifying the Problem
First, it’s vital to verify that the problem is indeed with the fuse and not the device you’re connecting. Try using another device to see if it functions properly. If multiple devices fail to work, the next step is to inspect the fuse.
Understanding the Fuse Layout
The Mercedes E Class typically has several fuse boxes, often located in the engine compartment, the trunk, and the cabin. The cigarette lighter fuse is usually in the cabin fuse box, which can be found on the driver’s side, covered beneath the dashboard.
Various Mercedes models may have different fuse layouts, so it’s important to refer to your owner’s manual to understand the exact location and specification of the cigarette lighter fuse. Usually, the manual will provide a map outlining each fuse’s location, size, and purpose, making it easier to identify the correct one.
Steps to Replace the Fuse
- Ensure your vehicle is turned off and the keys are removed from the ignition. This prevents any electrical shock or further damage.
- Access the cabin fuse box by removing the cover. It may require a slight force, so be gentle to avoid damaging any clips.
- Locate the cigarette lighter fuse, which might be labeled either as “cigarette lighter” or “auxiliary power”. Typically, in the Mercedes E Class, it’s a 15 or 20-amp fuse.
- Use a fuse puller, or a pair of needle-nose pliers, to carefully remove the suspect fuse.
- Inspect the fuse. If you notice a broken wire or scorch marks, the fuse is blown and requires replacement.
- Replace it with a new fuse of the same amperage. Never use a fuse of a higher rating, as this can lead to electrical issues or even fires.
- After replacing, reattach the cover and test the cigarette lighter with an electronic device to ensure functionality.
Additional Tips
Maintaining a small kit of spare fuses in your glovebox can be extremely useful for emergencies. Since the cigarette lighter serves as a multipurpose power outlet, consistent use over time can lead to wear and shorts. Regular checks can mitigate unexpected issues.
Preventive Measures
To extend the life of your fuses and the cigarette lighter, keep the socket clean and free of debris. Regularly check for loose connections or corrosion, which can affect the functionality.
Periodically switch off or disconnect unused chargers or devices. Continuous charging can strain the socket and fuse, leading to potential failures.
Conclusion
Dealing with a failed cigarette lighter fuse in your Mercedes E Class doesn’t have to be a daunting task. With proper knowledge and the right tools, it can be a smooth and hassle-free process. Regular maintenance and vigilance are key in prolonging the life of your vehicle’s electrical components.
