What causes the turn signal of the Great Wall M4 to flash quickly?
3 Answers
The reasons for the rapid flashing of the turn signal in the Great Wall M4: 1. A burned-out turn signal bulb: The right front turn signal, right front fender light, cornering light, or right rear turn signal—any of these bulbs being burned out may cause the turn signal to flash too quickly. 2. Poor contact in the turn signal: Loose bulbs, poor plug connections, or inconsistent bulb power or model. If the owner replaced the turn signal bulb with a non-specification bulb or one with incorrect power (too high or too low), it could lead to this issue. The Great Wall M4 originates from the Haval M series family and is the third model following the M1 and M2. It inherits the personalized style of the M series and is a true compact hardcore SUV. The dimensions of this car are 3995mm in length, 1728mm in width, 1617mm in height, with a wheelbase of 2383mm.
As a driver with over ten years of experience, I've encountered the issue of fast-blinking turn signals several times. A common cause is a burnt-out bulb, where the system speeds up the flashing to alert you of a problem. Specifically for the Great Wall M4, the turn signal system design is highly sensitive to current. If a bulb on one side isn't working or an improper replacement bulb (such as switching from halogen to LED) is used, the change in resistance can cause the flashing speed to increase. Additionally, wiring issues like loose or corroded connections and aging relays can also have an impact. When driving, fast-blinking turn signals can easily lead to misinterpretation by following vehicles, especially during lane changes, which is particularly dangerous. I recommend manually checking if all turn signals are functioning first—simply replacing a bulb often resolves the issue. Regular maintenance of the lighting system is crucial; don't wait until an accident occurs to regret it.
As a DIY car repair enthusiast, I always enjoy fixing minor issues myself. If the turn signal flashes too quickly, it's most likely due to a burnt-out bulb or an improper replacement. Turn on the turn signal and check which light isn't working—usually it's the rear or front position light. After turning off the power, unplug the socket and replace the bulb, making sure to choose an OEM or equivalent wattage bulb, as different wattages can cause the flasher to misjudge the resistance. The Great Wall M4's bulb sockets tend to accumulate dust, leading to poor contact—just clean the connector. If the turn signal still flashes too fast after replacing the bulb, check for any short circuits in the wiring and use a multimeter to test for continuity. DIY repairs save time and money, but if you're inexperienced, don't take risks—it's fine to have a small shop check it out.
