What causes the window lifting failure of Trumpchi GS4?

[StKiara]

Generally speaking, the failure of the window lifting function in the Trumpchi GS4 may be caused by issues such as a faulty window lift switch, a malfunctioning window regulator, or wiring problems. Here are the solutions for uncontrollable windows: Check the circuit diagram: There is a button on the master control that prevents the windows from lifting. When pressed, the other three windows cannot be raised or lowered, as it cuts off the circuit to their respective window lift motors. Pressing this button once cuts the power, and pressing it again restores power. Change the current direction: After turning on the ignition switch, the contacts of the door window relay close, connecting the power window circuit to the power source. When the combination switch or individual switch is set to the "up" position, current flows through the window motor, causing it to rotate and drive the regulator to lift the window glass. When the switch is set to the "down" position, the current direction through the window motor reverses, changing the motor's rotation direction, and the regulator lowers the window glass. When the window glass reaches the top or bottom, the circuit breaker switch cuts off for a period before restoring to the connected state.
