Why can't the car window go up and down?

[LeHazel]

The reasons why the car window glass cannot go up and down: deformation or damage of the glass mud slot; loose screws fixing the lifter; damage to the window regulator; deviation in the installation position of the guide rail. For electric windows that cannot go up and down, first check whether it is a problem with some windows or all windows cannot go up and down. The following is an introduction to the car one-touch window function: 1. Function introduction: The one-touch window has two gears. When you want to open part of the window, you can use the first gear. To fully open the window, you can press it all the way down, and there will be a very small sound and feedback force. At this time, you can let it automatically lower the window. Generally, buttons with one-touch window function have anti-pinch function. For cars that often carry children, it is best to have this function, and the driver must lock all four windows on the control side while driving. 2. Definition: One-touch window refers to a system where the car window glass can be controlled to go up and down with one button. Ordinary electric windows require holding down the switch, and the window stops moving when the button is released at the desired position.
