Car Electrician Repairing Cigarette Lighter
A malfunctioning cigarette lighter in your car can be a real nuisance, especially if you rely on it to power your devices. While it might seem like a minor issue, a broken cigarette lighter can sometimes indicate a more serious electrical problem. This comprehensive guide will walk you through the common causes of a broken car cigarette lighter and provide you with a step-by-step guide on how to repair it yourself.
Common Causes of a Broken Cigarette Lighter
Before diving into the repair process, it’s crucial to understand what might be causing the issue. Here are some of the most common culprits:
- Blown Fuse: The most frequent cause is a blown fuse, which acts as a safety measure to protect your car’s electrical system from power surges.
- Faulty Cigarette Lighter Socket: Over time, the cigarette lighter socket can wear out, become loose, or accumulate debris, hindering its functionality.
- Wiring Issues: Damaged or corroded wires connecting the cigarette lighter to the car’s electrical system can interrupt the power supply.
- Malfunctioning Cigarette Lighter: The heating element inside the cigarette lighter itself can burn out, rendering it useless.
Troubleshooting Your Car Cigarette Lighter
Before attempting any repairs, it’s essential to troubleshoot the problem to determine the root cause. Here’s how:
-
Check the Fuse: Locate your car’s fuse box (refer to your owner’s manual if needed). Look for a fuse labeled “cigarette lighter,” “accessory power outlet,” or something similar. Visually inspect the fuse for any signs of damage, such as a broken wire or a darkened glass tube. If you suspect a blown fuse, replace it with a new one of the same amperage.
-
Inspect the Socket: With the fuse removed, carefully examine the cigarette lighter socket for any visible debris, dirt, or foreign objects. Use a flashlight for better visibility. If you find any, gently remove them using a small brush, compressed air, or a cotton swab.
-
Test the Socket: After cleaning the socket, insert a different 12V device, such as a phone charger. If the device works, the issue lies with your cigarette lighter itself. If not, the problem might be with the socket or the wiring.
How to Repair a Car Cigarette Lighter
If troubleshooting reveals that the cigarette lighter itself is the problem, you can try repairing it. Here’s a step-by-step guide:
-
Gather Your Materials: You’ll need a replacement cigarette lighter heating element (available at auto parts stores), a screwdriver, pliers, and possibly some electrical tape.
-
Disconnect the Battery: For safety, disconnect the negative terminal of your car battery before proceeding. This will prevent any electrical shorts.
-
Remove the Lighter Assembly: Depending on your car model, you might need to remove a trim panel or pry open the console surrounding the cigarette lighter socket to access the assembly.
-
Disconnect the Wiring: Carefully disconnect the wiring harness connected to the back of the cigarette lighter assembly.
-
Disassemble the Lighter: Gently pry open the cigarette lighter’s outer casing using a screwdriver. Be careful not to damage the internal components.
-
Replace the Heating Element: Remove the old heating element and replace it with the new one, ensuring it’s properly seated and connected.
-
Reassemble and Test: Carefully reassemble the cigarette lighter, reconnect the wiring harness, and secure the assembly back into the dashboard. Reconnect the car battery and test the lighter.
