2 Answers
Here are the reasons for the erratic jumping of the central lock in Baojun 730: 1. Damaged lock mechanism: A damaged lock mechanism causes the motor to keep working. 2. Sensor malfunction: A faulty sensor that detects whether the door is properly closed leads to confusion in the control computer, causing the motor to keep working. Here are the solutions for the erratic jumping of the central lock in Baojun 730: 1. Loose parts: Owners with some mechanical skills can remove the door panel and check if any components of the locking mechanism are loose or damaged. If any parts are found loose, they can be reinstalled. 2. Inspection and repair: If no specific fault is observed, it can be handed over to professionals for handling.
I've been driving the Baojun 730 for two years and encountered the issue of the door lock continuously jumping on its own. At first, I thought it was due to low battery in the remote key, but even after replacing it with a new one, the problem persisted. Later, I consulted a mechanic friend, who analyzed that it might be due to the door lock motor being stuck internally or oxidized contact points in the wiring causing repeated signal triggers. Dust and moisture can easily seep into the door interior, and over time, the wiring harness connectors can loosen. I personally removed the door panel to take a look and found that indeed, several wires had aged and broken. A simple soldering fix during the repair did the trick. I recommend first checking the wiring near the driver's side door lock and, if necessary, replacing the lock motor block, which isn't expensive—just a couple hundred yuan will cover it. Don't overlook small issues; a jumping lock not only drains the battery quickly but also affects driving safety. Addressing it promptly saves both peace of mind and money.
