What are the reasons why all four windows of the Teana cannot be raised or lowered?

[OscarFitz]

Introduction to the sudden inability to raise or lower the windows on all four sides of the Teana car: 1. Damage to the window lift motor or poor contact in the electrical control wiring: 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 are equipped with an overheating protection mechanism. If the components overheat for some reason, the motor will enter an overheating protection state, resulting in the failure of the window to raise or lower. 3. Excessive resistance in the glass guide channel: The door glass guide channel is a detail that is often overlooked. During use, dust accumulates in the glass guide channel, increasing resistance, which over time may make it difficult to raise the glass.
