Why can the one-touch window lift of the new Sylphy only lower but not raise?

[LaGeorge]

If the one-touch window lift of the new Sylphy can only lower but not raise, it may be due to a damaged window lift motor, poor contact in the electrical control wiring harness, motor overheating, or excessive resistance in the glass guide channel. Damaged window lift motor or poor contact in the electrical control wiring harness: If there is a burnt smell or unusual noise inside the door panel when holding down the window button for a long time, it is highly likely that the window lift motor components are damaged. In this case, it is recommended to directly visit a 4S shop or auto repair shop to replace the window lift motor. 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, causing the window lift to malfunction. 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. Over time, this may make it difficult for the glass to rise.
