What causes the random clicking sound from the lock button after locking the Excelle?

It could be due to a damaged small switch inside the central control motor of the left front door. Unplug the connector; if the issue stops, replacing the left front door central control motor should resolve it. Below is more information about the Excelle: Exterior: The all-new Excelle adopts Buick's next-generation family design language, featuring a new Buick family-style winged grille with dark mesh texture and a high-gloss electroplated shield-shaped outer contour, exuding youthful vitality. The winged headlights and grille form a diving angle, creating a dynamic appearance. Powertrain: The new vehicle is equipped with a next-generation 1.3L Ecotec dual injection engine, paired with a CVT intelligent continuously variable transmission, delivering a maximum power of 79kW and a maximum torque of 133Nm, with a combined fuel consumption as low as 4.6L per 100km.
I had a similar issue with my Excelle. After locking the car, the lock button kept clicking rapidly, which made me think it was haunted. Later, I found out it was due to the aging door lock motor getting stuck and repeatedly triggering the action, causing signal confusion in the button. This situation might occur because the door wasn’t fully closed, the sensor was falsely triggered, or there was a short circuit in the wiring. At the time, I tried restarting the car key, but it didn’t help. Then, I checked if the doors were completely closed and inspected the fuses—everything seemed fine. Eventually, I went to a professional shop recommended by a friend. They used a diagnostic tool and identified it as a motor failure. Replacing the motor cost a few hundred yuan and solved the problem. If the key button itself is faulty, like being clogged with dust, you can gently blow on it to clean it. Regularly inspecting door lock components during maintenance can prevent issues before they arise—don’t wait until you encounter problems at night when driving. Safety first. In short, there are many common causes, but before attempting any fixes, it’s best to consult someone knowledgeable.
