How to Reset the Mercedes-Benz Window Switch?
2 Answers
Mercedes-Benz window one-touch up/down malfunction recovery method is as follows: 1. Directly pull up the window button to raise the window to the top, then hold for 3 to 5 seconds before releasing; 2. Then press the window button to lower the window to the bottom, hold for 3 to 5 seconds before releasing. Finally, test the one-touch function to complete the reset. Below is more information about the one-touch window function: 1. One-touch window refers to a system where the car window glass can be fully opened or closed with a single button press. 2. Cars equipped with one-touch windows have two positions on the window control switch: the first position operates like a normal power window; the second position automatically fully opens or closes the window when pressed and released.
Recently helped my sister with her Mercedes-Benz C-Class window issue. Resetting the power window switch isn't actually difficult. First, turn the key to the ignition-on position without starting the engine, then press and hold the window switch to lower the glass completely for about 10 seconds. Next, continue holding the switch while raising the window to the top and maintain for another 10 seconds. You'll hear a slight clicking sound from the door, indicating the system has successfully reset. I find Mercedes' reset logic quite interesting - many German cars use similar designs. If there's still no response after this procedure, check whether the window regulator motor is stuck or if oxidized wiring connections are causing poor contact. In winter, frosted window tracks often cause such issues too, so it's best to apply some window lubricant preventatively.
