How to Restore the One-Touch Up/Down Function for Mercedes-Benz Windows?

[KatherineDella]

To restore the one-touch up/down function for the windows, you can reset it. The window control has two positions. When you want to open the window partially, use the first position. To fully open the window, press the button all the way down until you hear a slight sound and feel a feedback force, then the window will automatically lower. Here are the methods to restore the one-touch up/down function for Mercedes-Benz windows: 1. Method One: Lift the window button to raise the window to the top, hold it for 3-5 seconds without releasing, then let go. Next, press the window button to lower the window completely, hold it for 3-5 seconds without releasing, then let go. After this, test the one-touch up/down function, and it should work. 2. Method Two: If the one-touch function still doesn't work, it might be due to other issues such as a malfunctioning door control module, faulty window control button, or damaged lift motor. In such cases, you need to take the car to a 4S shop for repair.
