Why are the turn signals of Wuling Zhiguang not working?

[DeBennett]

It may be that the relay of the turn signal or the fuse of the turn signal is blown. These two reasons are important factors for the turn signal not working. The relay of the car turn signal can be replaced by yourself, but the fuse needs to be replaced by a professional. Acting rashly by yourself may cause greater car failure. The following is the relevant introduction: Definition of turn signal: The turn signal is an important indicator light that is turned on when the motor vehicle is turning to alert the vehicles and pedestrians around. The turn signal tube uses a xenon tube, and the single-chip microcomputer controls the circuit, working alternately left and right with uninterrupted flashing. The turn signal uses a flasher to achieve light flashing. It can be mainly divided into three types: resistance wire type, capacitor type, and electronic type. Function of turn signal: The turn signal is the most important device to indicate the dynamic information of the car. It is installed at the front and rear of the car body and is turned on when the car turns. It provides a guarantee for driving safety. For safety, please use the turn signal as required, so that people can know the movement of the car in advance and make correct judgments.

My Wuling Zhiguang also experienced turn signal failure before, and it turned out to be a burnt-out bulb. Turn signals blink all day long and have a short lifespan, especially when driving on rough roads carrying cargo—the constant jolting makes them more prone to failure. After opening the lamp cover, I found the tungsten filament was broken, and replacing it with a 10-yuan bulb solved the problem. If both sides stop working, it might be a blown fuse—the 10A mini fuse in the black box under the steering wheel is critical, so it’s best to keep a few spares in the car. Sometimes, humid weather can cause connector rust; just sand it lightly with sandpaper. For long trips with this vehicle, remember to carry spare bulbs—driving on the highway without turn signals is like driving blind, which is extremely dangerous.

Last time during maintenance, the mechanic said that the turn signal issues in the Wuling Zhiguang are mostly due to wiring problems. The wiring in this vehicle is rough, especially at the rear where frequent loading can squeeze the wire harness, and loading/unloading can easily loosen the connectors. After removing the rear light housing, I saw the plug wobbling—just pushing it tight fixed the issue. The turn signal switch is also quite fragile; in older cars, the copper contacts inside the lever can wear out over time, causing the switch to click but not light up when toggled. Also, listen for the flasher relay's sound—if the clicking is abnormal or absent, it's likely the culprit. I make it a habit to tap the light covers before each weekly haul to check if they light up. Maintaining a car is all about prevention.

Last month, the turn signals on my friend's Wuling Zhiguang suddenly all went out, and it turned out that the fuse box under the steering wheel had burned out. These vans have simple but fragile electrical systems; improperly wiring a sound system can easily blow the turn signal fuse. Check the diagram on the inside of the fuse box cover to locate the 10A position labeled for the turn signals. Some owners have also found the rear light wiring chewed through by mice, especially when parked in rural areas. Aging wiring is another concern—a mechanic used a multimeter to trace the circuit backward from the bulb and found a section of frayed wiring behind the dashboard. If the turn signals aren’t working, they must be fixed promptly, as changing lanes without them is downright scary.

When the Wuling Zhiguang's turn signal doesn't work, it's best to troubleshoot step by step. First, check if the green arrow icon on the dashboard lights up. If not, it indicates an issue with the entire circuit. Next, open the hood and inspect the connector of the lighting control module. Once, my car had a short circuit due to rainwater entering the interface. Then, test the flasher relay—a mechanic can use a jumper wire to check if it's functioning properly. Oxidized contacts on the turn signal switch are also common; spraying some rust remover can provide a temporary fix. The most troublesome issue is internal damage to the wiring harness. Last time, it took three days to locate the cracked wire at the door hinge area from repeated bending. During the rainy season, pay special attention to whether the waterproof sleeves on the wiring connectors have come off.

The veteran mechanic said that diagnosing a Wuling Zhiguang's turn signal issue depends on the symptoms. If the left side doesn't light up while the right side works fine, it's definitely a left circuit problem—check the bulb and socket. If both sides suddenly go out, check the fuse box first. If the turn signal lights up but flashes unusually fast, it's most likely due to incorrect bulb wattage or poor grounding. I've encountered cases where the turn signal stays lit without flashing, and it turned out to be a burned-out flasher relay chip. There was also a situation where the turn signal automatically lit up when the driver turned the steering wheel, which ended up being a clock spring issue. The turn signal wiring harness in this car is tightly routed, so after repairs, remember to re-secure and bundle it properly to prevent vibration-induced loosening and poor contact. Lighting issues shouldn't be delayed—I've seen accidents caused by turn signal failures.
