What is the reason for the unresponsive tailgate button on Changan Oushang?

If it cannot open automatically or cannot be opened with the remote control, it might be an issue with the motor. Below is a related introduction to Changan Oushang: 1.

My car is also a Changan Oushang. Once the tailgate button didn't respond, and it really worried me. It might be a blown fuse, which is the most common issue. Check the fuse box for the corresponding label and try replacing it. Wiring problems could also be the cause, like loose or aged button connections, or short circuits from rainwater exposure. The tailgate system might also have sensor or control module failures, which are more noticeable with temperature changes. I tried restarting the car myself, but it didn't help. In the end, I had to go to a repair shop to get it fixed, which didn't cost more than a few hundred yuan. Regular maintenance can prevent this—check the button interface for dust buildup monthly, and avoid pressing it too hard to prevent further damage. Safe driving is crucial; if the button fails, don't force the door open, as the tailgate could fall and injure someone.

From a repair perspective, there are generally several scenarios when the rear tailgate button is unresponsive: the button itself is damaged, or excessive wear causes the button to jam; wiring issues such as short circuits or breaks, which can be detected with a multimeter showing no current flow; relay problems are common in control circuits, where a burnt relay prevents signals from reaching the tailgate motor; system issues like low battery voltage or alternator problems affecting power supply; corroded button interfaces causing poor contact; and smart system failures, which are common in high-end models. I recommend first checking the fuse, located in the driver-side fuse box and marked with the tailgate symbol. If that's not the issue, it's best not to disassemble it yourself to avoid causing additional faults—take it to a professional shop for quick and safe diagnosis.

I'm quite familiar with automotive electronic systems. Unresponsive buttons often stem from simple issues. Blown fuses are common due to current overload - replacing them usually solves the problem. Button wear or oxidation affects sensitivity; try cleaning with alcohol. A faulty tailgate motor or control logic errors in the ECU module may cause more frequent issues during cold starts. Additionally, unstable vehicle voltage, aged/worn wiring, or external interference can trigger malfunctions. Maintain sufficient battery charge and prevent dust/water ingress on buttons. Most faults are easily repairable - don't delay repairs to avoid tailgate lockouts that could hinder luggage loading or emergency access.
