- Carefully disconnect the connections. Use wire strippers to carefully strip away any insulation.
- Clean corroded terminals. Use a wire brush or a cleaning solution to remove any corrosion or oxidation from the terminals. Be cautious not to damage the metal.
- Tighten the connections. Ensure that all connections are secure and tight.
- Apply electrical tape to the connections to ensure a secure and water-resistant seal.
- Reconnect the connections and test the cigarette lighter.
Malfunctioning Switch Troubleshooting
A faulty cigarette lighter switch can prevent the lighter from working. Diagnosing the issue involves testing the switch’s functionality.
- Test the switch’s operation. Ensure the switch is properly engaging when pressed.
- Inspect the switch for visible damage or wear.
- If the switch is faulty, consider replacing the entire cigarette lighter assembly.
- If the switch is operational but not activating the circuit, it might be an issue in the electrical wiring.
Replacing the Cigarette Lighter Switch
Replacing the cigarette lighter switch might be necessary if the switch itself is faulty. This involves disconnecting wiring, removing the old switch, and installing the new switch. Follow the instructions in your vehicle’s repair manual for specific procedures.
- Disconnect the negative terminal of the battery.
- Locate the switch connections and carefully disconnect the wiring from the old switch.
- Remove the old switch from its mounting location.
- Install the new switch, ensuring proper alignment and secure connections.
