The proper functioning of a car's turn signals is crucial, and any malfunction should be promptly addressed to avoid safety hazards. If your car's turn signals work intermittently, what could be the issue?
1：Poor contact between the turn signal bulb and the socket can cause intermittent issues. Reinstalling the turn signal bulb securely onto the socket is necessary to address the on-and-off behavior.
2：Mismatched turn signal bulbs with the vehicle can lead to intermittent problems. If a higher wattage bulb was installed after a previous burnout, the turn signal may work intermittently. In such cases, it's advisable to visit a dealership (4S store) to replace the bulb with one that matches the vehicle's specifications.
3：Burned-out filaments in the bulb can also result in intermittent turn signal operation. As bulbs age, their filaments may deteriorate, requiring replacement with new bulbs.
4：A faulty flasher relay in the car's turn signal system can be the culprit. Using a multimeter to measure voltage is recommended. Normal voltage output should be a consistent 12V. If there is a continuous or no output, it indicates a damaged flasher relay, necessitating replacement, which can be done at a 4S store.
