What are the reasons why the Baojun 730 window regulator is not working?
2 Answers
The reasons why the Baojun 730 window regulator is not working can be attributed to the following three aspects. Window regulator motor damage or poor contact in the electrical 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 regulator motor components are damaged. In this case, it is recommended to directly contact a 4S shop or auto repair shop to replace the window regulator motor. Motor overheating protection: To protect the power supply circuit, most window regulator motors are equipped with an overheating protection mechanism. If the components overheat for some reason, the motor will enter an overheating protection state, resulting in window regulator failure. Excessive resistance in the glass guide channel: The door glass guide channel is a detail that is often overlooked. During use, dust can accumulate in the glass guide channel, increasing resistance, which over time may make it difficult for the window to rise.
I've been driving for ten years, especially the Baojun series, and have encountered window regulator failures several times. Common causes include blown fuses, usually due to current overload, or worn-out switch buttons causing poor contact; the lifting motor may fail due to frequent use leading to aging or water damage; loose or corroded wiring connections can also interrupt power supply; dust accumulation or deformation in the glass tracks can prevent movement. I've fixed it myself before—simple issues like replacing a fuse can be resolved by spending a few dollars on a new one, with the fuse box located under the driver's seat. For more complex problems, such as a faulty motor indicated by a clicking sound, it's best to promptly visit a repair shop for inspection to avoid bigger issues affecting door locks or driving safety. Regular cleaning of window gaps can help reduce the occurrence of faults.
