Why does the Buick Excelle's door lock keep jumping by itself?

Buick Excelle door lock keeps jumping may be caused by poor lock block actuator or poor line contact. In this case, you need to go to a 4S store for repair or replacement. Here is some relevant knowledge about the Buick Excelle: 1. Model: The Buick Excelle is a hatchback model. The Buick Excelle HRV is a type of general vehicle produced by Shanghai GM, belonging to the new standard of mid-size cars. 2. Appearance and interior: The appearance has a highly sculpted European style and refined and concise aesthetic elements. It is the latest globally developed mid-size car by General Motors. The interior of the Buick Excelle is high-end, not complicated, but very practical.
Regarding the issue of my Excelle's door locks randomly jumping after being locked, I suspect it might be a problem with the door lock control module. This component controls the locking and unlocking actions, and if there's an internal short circuit or aging, it can cause malfunctions leading to the locks jumping on their own. Another common cause is poor wiring connections, such as wear and tear on the wire harness at the junction between the door and the body, resulting in incorrect signal transmission and repeated jumping of the door locks. It could also be the door lock actuator, that small motor, getting stuck or encountering too much resistance, causing the system to mistakenly think the lock isn't engaged and repeatedly attempt to lock it. I've experienced a similar situation myself—first, I checked the fuse box and found the fuse for the door locks was intact. Then, using a multimeter, I tested the wiring and noticed unstable voltage. I recommend you visit a professional shop as soon as possible to read the fault codes with a diagnostic tool to avoid the risk of the locks unexpectedly popping open while driving. Alternatively, try cleaning the door locks and contacts, as accumulated dust or oxidation can sometimes cause such strange behavior.
