It may be covered by a plastic panel that you need to remove. Once you have located the fuse panel, consult your vehicle’s owner’s manual to identify the fuse that is responsible for the cigarette lighter.
Fuse panels can vary in location and design depending on the make and model of your vehicle. Here are some general tips for finding the fuse panel:
- Check the owner’s manual for the location of the fuse panel.
- Look under the dashboard, on the driver’s side.
- Check the engine compartment for a fuse box (usually near the battery).
- If you can’t find the fuse panel, consult with a mechanic.
Once you have located the fuse panel, you need to identify the fuse that is responsible for the cigarette lighter. The fuse will be labeled with a number or a symbol that corresponds to the circuit that it protects. The owner’s manual will provide a diagram of the fuse panel that will help you identify the correct fuse.
Using a Test Light
A test light is a handy tool for checking fuses, as it provides a quick and easy way to determine if a fuse is blown or not. To use a test light to check a cigarette lighter fuse:
- Turn off the engine and disconnect the negative battery terminal.
- Locate the fuse box, which is typically located under the dashboard or in the engine compartment.
- Identify the fuse that corresponds to the cigarette lighter. This information can usually be found in the owner’s manual or on the fuse box cover.
- Remove the fuse from the fuse box using a fuse puller or needle-nose pliers.
- Connect the test light to the battery terminal that you disconnected in step 1. The test light should illuminate if it is working properly.
- Touch the other end of the test light to one of the terminals on the fuse. If the test light illuminates, then the fuse is blown and needs to be replaced.
- Repeat step 6 for the other terminal on the fuse. If the test light does not illuminate for either terminal, then the fuse is most likely good and does not need to be replaced.
- Reconnect the battery terminal and turn on the engine to verify that the cigarette lighter is working properly.

Checking with a Multimeter
Checking the Fuse with a Multimeter
Using a multimeter to test the cigarette lighter fuse is a straightforward process that requires minimal tools and experience. Here’s a detailed guide on how to do it step-by-step:
- Gather your tools: You will need a multimeter and a pair of probe leads.
- Prepare the multimeter: Set the multimeter to the “Continuity” or “Ohms” mode, which is typically denoted by a symbol resembling an inverted horseshoe.
- Identify the fuse terminals: Locate the fuse box, usually situated beneath the dashboard or in the engine bay. Identify the specific fuse responsible for the cigarette lighter and note its location.
- Connect the probes: Touch one probe to one terminal of the fuse and the other probe to the other terminal. If the fuse is intact, the multimeter will emit a continuous beep or display a reading of 0 ohms, indicating electrical continuity.
- Interpret the results: If the fuse is blown, the multimeter will not display any reading or beep. This indicates a break in the fuse’s conductive path, and the fuse needs to be replaced.
Additional Tips
- Before attempting any electrical work, ensure the vehicle is parked and the engine is turned off.
- If you are not comfortable working with electrical components, consult a qualified mechanic for assistance.
- If the fuse is blown, replace it with a fuse of the same amperage rating to avoid potential electrical hazards.
Testing the Power Source
The most common cause of a cigarette lighter fuse blowing is a short circuit in the power source. To test the power source, you will need a multimeter.
1. Set the multimeter to DC volts.
2. Connect the black lead of the multimeter to the negative terminal of the battery.
3. Connect the red lead of the multimeter to the positive terminal of the battery.
4. The multimeter should read 12 volts.
If the multimeter does not read 12 volts, then there is a problem with the power source. You will need to troubleshoot the power source to find the problem.
Here is a table of possible problems and solutions:
| Problem | Solution |
|---|---|
| Battery is dead | Replace the battery |
| Battery terminals are corroded | Clean the battery terminals |
