What to Do When the Turn Signal of BYD Surui Doesn't Work?

[StJoanna]

Check if the turn signal fuse is blown. Observe whether the road conditions allow overtaking. If overtaking is possible, first turn on the left turn signal and wait until after overtaking. If the turn signals do not light up at all when the turn signal switch is turned on after short-circuiting the two terminals of the flasher, observe whether the road conditions allow overtaking. If all turn signals light up when the hazard warning switch is turned on, it indicates a fault in the turn signal switch or the wiring from the turn signal switch to the flasher. If the turn signals still do not light up when the hazard warning switch is turned on, focus on checking the circuit faults according to the circuit diagram. In China, it is required to overtake on the left side of the vehicle in front.

I've been driving a BYD Surui for several years, and the turn signal not working is a minor but common issue. My first instinct is usually to check if the bulb has burned out—I pop open the hood or the rear light cover to see if the bulb glass has turned black. If it's faulty, I just buy a new bulb to replace it. The model is universal, but it's best to match the original to avoid compatibility issues. Next, I check if the fuse has blown. The fuse box in the BYD Surui is under a small cover to the left of the steering wheel. Locate the turn signal fuse and replace it with a new one—it only costs a few bucks. If these steps don’t fix it, the problem might be worn contacts in the turn signal switch or a stuck relay. The relay is in the engine compartment’s fuse box. A light tap might get it working again, or you can test the voltage to diagnose the issue. Aging wiring, like loose connections or corrosion, can also cause a circuit break. Over time, wires tend to develop minor issues. Driving with a faulty turn signal is risky—I’ve had a close call with a rear-end collision before—so never drive around with it broken. Pull over and turn on the hazard lights instead. Regularly checking all vehicle lights during maintenance can prevent such faults and save you from costly emergency repairs. Overall, fixing it isn’t hard, but it’s important to address it promptly.

I'm the kind of person who loves tinkering with cars and enjoys DIY repairs. When the turn signal on my BYD Surui doesn't work, I definitely try to fix it myself first. The most common issue is a burnt-out bulb—just remove the lamp cover, confirm the problem, and replace it with a new bulb, which is easy to find at any supermarket. Blown fuses are also not uncommon; the fuse box is located in a small panel next to the driver's seat. Find the turn signal fuse, pull it out, and replace it with a new one, and it should light up again. If the switch button is loose or unresponsive, the contacts might be dirty—just lightly sand them with sandpaper. For wiring issues, I often use a multimeter to check voltage and locate short circuits or breaks. If the connectors are rusty, clean them and see if that helps. However, if you're not confident in your skills, don't push it. Driving without functional turn signals is risky—you could get a ticket or even cause an accident. In such cases, it's better to leave it to a professional shop for peace of mind and safety. DIY repairs can save money, especially for small parts like bulbs and fuses, which are cheap and easy to replace. Just remember to turn off the power before working to avoid electric shocks. Once fixed, you can drive with confidence. Don't neglect the safety signal system—address it promptly.

I get nervous when the turn signal on my BYD Surui stops working, fearing a police check or an accident. I usually try turning the switch off and on a few times; sometimes it's just a brief poor contact and it comes back. If that doesn't work, I check under the hood to see if the rear bulb has dimmed or turned black, then buy a new bulb and replace it myself for convenience. If that still doesn't fix it, I immediately turn on the hazard lights, pull over, and find a repair shop to check—it might be a blown fuse or wiring issue that needs a professional's attention. Driving without turn signals makes lane changes dangerous, so I try to change lanes as little as possible to reach my destination safely. The repairs aren't expensive, but since it's about driving safety, it's best to fix it quickly and not delay.

At my age, I've seen plenty of driving experiences, and the BYD Surui's turn signal not working is a common sight. I'm used to giving the turn signal lever a few taps first—when there's poor contact, it can reconnect. If tapping doesn't work, then check the bulb and fuse; if the bulb is blackened, replace it, and if the fuse is blown, swap it out—it's easy to find in the box under the steering wheel. If that still doesn't fix it, it's likely an issue with the wiring or the switch internals, and you'll need a professional repair shop—don't try to fix it yourself. Driving without working lights is really dangerous—cars behind can easily rear-end you, so I just drive slower and use other lights to signal for safety. Regular maintenance and light checks can prevent issues early, saving money and hassle. Safe driving is the top priority—can't afford to be careless.

I'm an automotive technology enthusiast and have studied the BYD Suri turn signal controlled by the BCM module not lighting up, which might be a signal issue. First, I simply checked the bulb and the fuse inlet—burnt-out bulbs or blown fuses are the most common causes; replacing them yourself can often fix the issue. If those are normal, test the relay in the engine compartment fuse box using a multimeter to check for power. Short circuits or broken wires can also cause the problem—measure voltage at relevant points to locate the fault. BCM failure requires professional diagnostic tools, which 4S shops have for inspection. Fix it early to avoid driving hazards—use hazard lights to signal while driving to prevent accidents. BYD models have similar circuit structures, but consulting the manual is more accurate to avoid misjudgment. Safety first—address it quickly.
