What causes the driver's window of the Besturn B50 to malfunction?

[TaylorRose]

The reasons for the malfunction of the driver's window in the Besturn B50 include deformation or damage to the window's mud channel, loose screws on the window regulator, or damage to the window regulator itself. The solutions are as follows: Diagnostic computer reset: After connecting to the vehicle, select 'Close and Lock Function,' click 'Windows,' choose the window that needs to be reset, and then click 'Next' to start the initialization setup. The window will automatically move up and down twice to learn its limit positions. After the reset is complete, exit the program and test the window function. Manual reset method: Turn on the ignition switch, pull and hold the switch up until the window reaches the top, then continue holding for more than 3 seconds. Release the switch and immediately press and hold it down to lower the window to the bottom for more than 3 seconds. Repeat the upward movement once more to complete the initialization process, restoring the window's functionality.
