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.
