What Causes a Car's Turn Signal to Suddenly Stop Working?
2 Answers
Possible reasons for a car's turn signal suddenly not working include wiring faults, a damaged flasher relay, or a burnt-out bulb. Below are detailed explanations: Wiring Faults: A broken circuit or a blown fuse in the wiring can cause the turn signal to stop working suddenly. It is necessary to check the continuity of the wiring. Damaged Flasher Relay: The flasher relay, also known as the flasher, generates intermittent current to supply the turn signal lights, causing them to flash on and off. If it is damaged, the turn signal will naturally fail to light up. Burnt-Out Bulb: If the turn signal bulb has reached the end of its lifespan or is burnt out due to excessive current, the turn signal will not function properly.
I recently experienced the sudden failure of my turn signal. One night while driving, I found that the turn signal didn't respond, which was quite alarming. The most common cause is a burnt-out bulb. Bulbs endure constant vibration and high temperatures, so it's normal for the filament to break. If the bulb is fine, check if the fuse has blown—the fuse box is located under the steering wheel, and it's easy to inspect. If that's not the issue, it might be poor wiring contact, like a loose plug or aged, cracked wires. I recommend starting with the simplest fixes: replacing the bulb or fuse costs just a few bucks and can be done yourself. But if the problem persists, it's best to visit a professional auto repair shop to check the circuit. Don't drive recklessly to avoid accidents due to signal failure. Regular checks of your lighting system can prevent such issues.
