Why is the right turn signal not working?
2 Answers
There are several reasons why a car's turn signal may not be working: 1. No power to the flasher relay's live wire terminal: If there is no power, check for any breaks in the wire leading to the power source. If there is power, use a screwdriver to connect the two terminals of the flasher relay. If the turn signal lights up, it indicates a fault in the flasher relay, which should be replaced promptly. 2. Faulty flasher relay: Open the flasher relay cover and check if the coil and resistor are intact. If the resistor heats up and the contacts fail to close, press the movable contact. If the turn signal lights up, it indicates a fault in the relay. 3. Turn signal not lighting up: This could be due to a faulty turn signal switch. Use a screwdriver to connect the live wire of the turn signal switch to the left and right light wire terminals separately. If the light comes on, it means the turn signal switch is faulty and should be removed for repair or replacement.
A few days ago, I encountered an issue with the right turn signal not working while driving my colleague's car. When discussing repairs, I told him this is quite common—usually caused by an aging bulb or poor contact, but don’t rush to fix it yourself, as it’s easy to mess up. If the bulb looks intact, the fuse might be blown. Just open the fuse box, find the one corresponding to the turn signal, and replace it. Sometimes, a short circuit in the wiring can also be the culprit, like water seeping into the connector or aging wires. You’d need a multimeter to check, but I’d recommend going straight to a repair shop. A professional technician can fix it in minutes—after all, driving without a turn signal is risky and can easily lead to rear-end collisions. Safety first! I’ve seen many similar cases while working on cars. Remember to check these details during routine maintenance.
