Mercedes Benz C230 Turn Signal Light

Culprits behind Mercedes Benz C230 Turn Signal Light Problems

Turn signal lights on your Mercedes Benz C230 are there to alert other drivers when you are about to turn or stop. Keeping them in tiptop shape helps prevent road mishaps that are caused by miscommunication. Over time, these lights may lose their efficiency since they are not immune to wear and tear. One day, you might find them flashing too fast or too slow, or they may not even work at all. If you think your turn signal lights have already exceeded their service life, you'd better perform some troubleshooting right away. Listed below are the common culprits behind Mercedes Benz C230 turn signal light problems.

Turn signals blink too fast

A usual problem encountered with turn signal lights is that they blink really fast. Luckily, diagnosing this problem is easy because the most common culprit is bulb failure. To check your component, just look for damage in the bulbs. Faulty bulbs trigger the resistance switch to make the lights blink faster. If you find that the bulbs are in good shape, then it's time to check for a faulty combination switch because turn signal lights without enough voltage can also cause the lights to blink faster. However, if this is still not the case, then the ground connection for the combination switch should be the problem. Make sure that the connections are clean so that the turn signal lights can work efficiently.

Turn signals light but do not flash

If you find one of your Mercedes Benz C230's turn signal lights to be defective, the bulb or the electrical wiring is usually the culprit. But if both turn signals on the same side pose a problem, then you might have a flasher defect. The easiest way to test if the flasher is defective is by replacing the original flasher. Luckily, locating the flasher should be easy with your owner's manual. In addition, these parts are also inexpensive. If replacing the flasher does not solve the problem, then the problem lies on the bulbs or the wiring.

Turn signals do not work

Defective fuses also prevent turn signals from lighting. Aside from keeping the bulbs in good shape, the fuses must always be kept clean in order to work because these parts are more susceptible to corrosion, which can lead to faulty turn signal lights.

  • Tips to Keep Mercedes Benz C230 Turn Signal Lights in Top Shape 04 March 2014

    Even if your car's turn signal lights are engineered to provide optimum resistance to wear and tear, these parts should still be kept in good shape and cleaned regularly to prevent premature corrosion. Failing to perform regular maintenance can lead to several lighting issues like blinking too fast or too slow, which can compromise yours and your passengers' safety. So if you want to keep these dangers at bay, then follow these easy and trouble-free turn signal light maintenance tips:

    • Keep the wires, fuses, and connections clean.
    • If you want to keep your turn signal lights in top shape, you should look after not only the bulbs but also the wires, fuses, and connections. In fact, if these parts are left with dirt or with grime, they can greatly affect the lights' performance. Rust and corrosion should be swept away gently with a small brush or toothbrush so that the surface won't get damaged.
    • Keep the bulb sockets clean.
    • Keeping the housing clean can greatly extend the service life of the turn signal bulbs. Be sure to inspect for burn marks or signs of moisture so you can easily address replacement or cleaning. These signs of corrosion can easily be prevented by applying contact lubricant. In addition, look for cracks or small holes, and find time to apply a sealant. If you suspect any resistance defects, use an ohm meter or multimeter to test the turn signals.
    • Employ a twisting motion of your finger tip when wiping corrosion.
    • It is also important to take note of how you clean or wipe off the grime. You see, a twisting motion of your finger tips while wiping dirt is the most efficient way in cleaning off unwanted particles. This simple procedure ensures that no grime is left untouched.
    • Use the right type of cleaning materials.
    • When cleaning the disconnected socket, use only electrical contact cleaners to prevent further damage. Luckily, this cleaning material is readily available in auto supply stores. If you don't have time to buy one, white vinegar should work well as an alternative. Take note that if there is much dirt and grime present in the socket, soak it for around 10 minutes.
