What is the reason for the right window of the Focus not being able to go up or down?

[OSadie]

The reason the right window of the Focus cannot go up or down is due to a damaged window regulator motor. Precautions for using the window are as follows: 1. Clean the window glass: Dirty window glass not only affects appearance and visibility but also impacts the opening and closing of the power window. To prevent rainwater from entering the car, a rubber strip is attached to the upper part of the window frame, which is also the area that frequently contacts the glass. Excessive dirt on the glass increases friction with the rubber strip, affecting the window's operation, so it is essential to keep the glass clean. 2. Lubricate the lifting mechanism: The main reason for the power window switch not operating smoothly is often the depletion of lubrication oil inside the door's lifting mechanism. Therefore, the lifting mechanism should be regularly oiled and lubricated. 3. Check the rubber supports: After lubricating the lifting mechanism, inspect the rubber parts supporting both ends of the glass. If the glass slides poorly, apply a rubber protector.
