What to Do When the Windows of Baojun 730 Cannot Be Rolled Up or Down?
3 Answers
Solutions for the windows of Baojun 730 that cannot be rolled up or down are as follows: 1. The window lift motor is damaged or there is poor contact in the electrical control wiring harness. If there is a burnt smell or abnormal noise inside the door panel when holding down the window button for a long time, it is likely that the window lift motor components are damaged. In this case, it is recommended to directly contact a 4S shop or auto repair shop to replace the window lift motor. 2. Motor overheating protection. To protect the power supply circuit, most window lift motors have an overheating protection mechanism. If the components overheat for some reason, the motor will enter an overheating protection state, causing the window to fail to roll up or down. In this situation, simply wait for the motor to cool down. 3. Excessive resistance in the glass guide channel. The door glass guide channel is a detail that is easily overlooked. During use, dust can accumulate in the glass guide channel, increasing resistance, which may over time make it difficult for the glass to rise. Regularly clean debris from the window glass guide rails or use lubricating grease for lubrication.
If the windows of my Baojun 730 suddenly stop working, I usually start by checking the simplest parts. Open the fuse box to see if the fuse corresponding to the window has blown. The fuse location in the Baojun 730 might be under the steering wheel or near the engine. Pull it out and check if the black line is broken. A blown fuse is the most common issue—just replace it with a new one, and it should work. If the fuse is fine, try pressing the button to listen for any motor sound. If there's no sound, it might be due to poor switch contact. Test with other window buttons—if they work normally, the problem likely lies in the switch circuit. If none of the windows work, it could be a short circuit or a main control failure. A stuck window regulator or a faulty motor can also prevent the window from moving, which is more common in rainy or humid areas where metal tracks rust or wires degrade. In such cases, I personally make an emergency adjustment to open a small gap for ventilation and drive to a proper repair shop as soon as possible to check the circuit and prevent safety risks, since being unable to open or close windows while driving is a big issue. If you want to DIY, I’ve briefly watched YouTube tutorials on removing door panels, but doing it wrong could damage the car. Baojun parts are affordable, but I wouldn’t recommend beginners to tinker with them.
When encountering window lift failure, I directly troubleshoot the issue manually. Based on experience from the Baojun 730 owner forums, I would first test all window buttons to see if it's just one that's not working. If none respond, it might be a faulty master switch or a blown fuse. The fuse box is located near the glove compartment on the passenger side—pulling it out to inspect and replace costs just a few bucks. If a single window isn't moving but the button responds without any motor sound, the lift motor might be dead or the track could be jammed. Last time, I helped a friend remove the door panel to check for loose wiring connections—just carefully use a screwdriver to open the panel and inspect the tightness of the connections. Humid rainy seasons can easily cause track rust leading to jamming; try adding more lubricant. Short circuits are a headache and require a professional technician to test voltage with a meter. If you're handy, you can refer to the manual and do it yourself to save money, but safety first—avoid high-voltage areas. The window lift assembly for the Baojun 730 is relatively affordable, around 200 RMB, but it's recommended to choose OEM parts for durability. Usually, minimizing window operation while driving reduces wear and extends lifespan.
