The Mercedes E Class is a luxury vehicle renowned for its comfort and advanced features. Among its multiple components, the cigarette lighter is a part often overlooked until it stops functioning. A common cause for this issue is a blown fuse. Fortunately, locating and replacing the cigarette lighter fuse is a task that can be managed with ease, even without professional assistance.

Identifying the Fuse Box Location

Firstly, to address issues related to the cigarette lighter, you will need to locate the fuse box. In most Mercedes E Class models, the primary fuse box is located under the hood. Specifically, it’s near the driver’s side, mounted close to the windshield. However, there might also be additional fuse boxes located under the dashboard on the left side of the steering wheel for interior functionalities.

Accessing the Fuse Box

Gaining access to the fuse box is relatively straightforward. Open the driver’s door and locate the dashboard panel which can be gently pried open with minimal force. Once you remove this panel, you will see the fuses arranged in an orderly manner. To avoid any damages, ensure the car is turned off to prevent any electrical mishaps.

Finding the Correct Fuse

The Mercedes E Class manual typically provides a diagram of the fuse box layout. This diagram will indicate which fuse corresponds to the cigarette lighter. Typically, it is labeled with a specific number that you’ll need to identify. In the Mercedes E Class, the cigarette lighter fuse is often a 15-amp fuse, but it’s crucial to confirm this via your user manual to avoid confusion.

Upon locating the correct fuse, pull it out carefully using a fuse puller or a pair of tweezers. Inspect the metal wire inside; if it appears broken, the fuse needs replacing.

Replacement and Testing

Installing a New Fuse

Once you have removed the damaged fuse, you can replace it with a new one of the same amperage. Gently press the new fuse into the slot until it is fully seated. Make sure that the metal connectors are aligned properly to ensure it functions correctly.

After replacing the fuse, test the cigarette lighter by starting your vehicle and plugging in a compatible device. If the device powers on, the problem is resolved. If not, there may be further issues with the wiring or the lighter component itself, which may require professional attention.

Preventive Measures

To prevent future issues, avoid using devices that exceed the lighter’s power capabilities. Consistently check your vehicle’s power outlets and ensure plugs aren’t left inside when not in use. These simple steps can extend the longevity of your cigarette lighter fuse and maintain overall vehicle health.

For those unfamiliar with vehicle electronics, the user’s manual and fuse box diagram are invaluable resources. Utilizing these resources can simplify the troubleshooting process significantly.
