Where is the cigarette lighter fuse located in a Mercedes-Benz?
3 Answers
Mercedes-Benz cigarette lighter fuse is located under the side cover panel in the vehicle's trunk. Location of Mercedes-Benz fuse boxes: There are a total of six fuse boxes in Mercedes-Benz vehicles. The main circuit fuse box is located at the upper right of the engine compartment, while the others are positioned on the left side of the trunk. They feature a rotary switch mechanism - simply turn to open and access the fuse box inside. Function of automotive fuses: Automotive fuses serve as current protection devices. When circuit current exceeds twice the rated current, they automatically melt and break within seconds. This safeguards the circuit by preventing excessive current flow, thereby avoiding circuit failures or fire hazards. As temperatures rise, fuses become more prone to burning out.
As a Mercedes-Benz owner, my car's cigarette lighter suddenly stopped working, and I found out it was due to a blown fuse. The fuse box location varies by model: commonly found under the dashboard on the driver's side, where a small cover can be lifted to reveal a cluster of fuses; for example, in the C-Class, it's at the left corner of the glove box, while the S-Class may have it moved to the right front side under the hood. The manual indicates the corresponding number for the cigarette lighter, usually marked with an 'F' followed by a number. Use a plastic clip to pull it out and inspect—if it's broken, replace it with a new fuse of the same amperage, typically 10A or 15A. DIY replacement is simple, but make sure to turn off the engine and remove the key first, waiting a few minutes to avoid short circuits. The cigarette lighter isn't just for lighting cigarettes; nowadays, it's often used for phone chargers, and overload can easily cause it to blow. I recommend regularly checking the fuse condition—safety first. Getting it fixed at a 4S shop costs very little, but don’t delay too long as it might affect nighttime driving illumination.
As a DIY car repair enthusiast, troubleshooting cigarette lighter issues usually starts with the fuse. Mercedes fuse box locations vary: older models have them under the dashboard with a flip-up cover, while newer models like the GLE might have them in the trunk compartment lining; check the manual diagrams or use a multimeter to test continuity. Once you identify the correct fuse number (e.g., Fuse 15), make sure to match the amperage when replacing it. Simple tools like small pliers and a test light are sufficient. Remember to turn off the power to prevent circuit damage; if the fuse blows repeatedly, inspect the cigarette lighter socket for debris or wear. Cigarette lighters often use USB adapters, and exceeding the power limit can cause issues; I prefer searching model-specific guides on online forums for precise troubleshooting. DIY fixes save time and money, but non-experts should always keep manual diagrams as backup.
