What Causes the Failure of Automatic Window Roll-up and Roll-down?

[DiNathan]

The failure of automatic window roll-up and roll-down can be attributed to several reasons: First, the aging and deformation of the glass sealing strip, which requires replacement of a new sealing strip or application of talcum powder for lubrication if not severe; second, the window lift guide rail being too dirty or obstructed by foreign objects, necessitating cleaning and application of grease; third, motor failure or low battery charge, requiring charging or motor replacement. Aging and Deformation of Glass Sealing Strip: Aging, excessive dirt, or deformation of the glass sealing strip can create resistance to the window's upward or downward movement. It is best to replace the sealing strip, or simply clean it if it's just dirty. Spraying some dashboard wax or applying talcum powder to the glass sealing strip can usually yield good results. Dirty Window Lift Guide Rail: This is also a lubrication issue. Cleaning the window lift guide rail and applying grease can eliminate the malfunction. Low Battery Charge or Motor Failure: When rolling up or down the window without the engine running, the power is drawn from the battery. If the battery charge is too low, difficulties in window movement may occur. If there is difficulty in rolling the window when the battery is sufficiently charged and there is no resistance, it is highly likely due to motor failure.
