1. Checking the Fuse

The first and most important step in troubleshooting a BMW cigarette lighter not charging is to check the fuse.

The fuse is responsible for protecting the electrical circuit of the cigarette lighter from excessive current flow.

If the fuse is blown, it can disrupt the power supply to the cigarette lighter and prevent it from charging any devices.

Following are the steps to check the fuse:

1. Locate the Fuse Box In Your BMW:

The fuse box is typically located in the glove compartment, under the dashboard, or in the trunk, depending on the BMW model.

Refer to your vehicle’s manual or consult the manufacturer’s website for the exact location.

2. Identify the Fuse Corresponding to the Cigarette Lighter:

Look for the fuse labeled specifically for the cigarette lighter or accessory power outlet. The fuse box cover or the manual should provide a diagram or description of the fuse layout.

3. Check If the Fuse Is Blown:

Start by turning off the vehicle’s ignition to prevent any electrical hazards. Remove the fuse in question from its socket.

Inspect the fuse visually to see if the metal strip inside is intact or broken. Alternatively, you can use a multimeter to test the fuse.

4. Replace the Blown Fuse:

If the fuse is blown, replace it with a new fuse of the same rating. The fuse rating is usually indicated on the fuse itself or in the owner’s manual.

Make sure to use the correct amperage fuse to prevent electrical damage or hazards. Carefully insert the new fuse into the appropriate socket, ensuring it is fully seated.

2. Checking the Wiring

Checking the wiring of the cigarette lighter is an essential step in troubleshooting charging issues.

Here’s how you can perform this task:

1. Visual Inspection:

Carefully examine the wiring leading to the cigarette lighter for any signs of damage, such as frayed or worn-out insulation, exposed wires, or loose connections.

Look for any physical abnormalities that could be affecting the charging functionality.

2. Repair or Replace Damaged Wires:

If you spot any damaged wires, it’s crucial to repair or replace them. Cut out the damaged section of the wire, ensuring to leave enough length for reconnection.

Strip off a small portion of the wire insulation at both ends and use electrical connectors or soldering techniques to join the wires securely.

Alternatively, if the damage is extensive, it might be necessary to replace the entire wiring harness.

3. Secure Connections:

Ensure that all connections, including those between the wiring and the cigarette lighter, are secure and properly connected.

Double-check the tightness of the screws or connectors to eliminate any loose connections that can interfere with the charging process.

By thoroughly inspecting the wiring and addressing any issues, you can ensure a reliable electrical connection for your cigarette lighter and maximize its charging capabilities.
