The reason why the left rear door of the Focus cannot be locked and the window cannot be raised or lowered is due to a damaged window regulator motor. Precautions for using the window: Clean the window glass: Dirty window glass not only affects appearance and visibility but also interferes with the opening and closing of the power window. To prevent rainwater from entering the car, there is a rubber strip 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, thereby affecting the window's operation, so it is essential to keep the glass clean. Lubricate the lifting mechanism: The main reason for the power window switch not operating smoothly is often the depletion of lubricating oil inside the door's lifting mechanism. Therefore, the lifting mechanism should be regularly lubricated. The lubrication method is as follows: First, remove the inner cover, peel off the waterproof plastic sheet below, remove the hidden screws, and detach the quick-action switch; then spray grease inside the window gear, moving it up and down while spraying to ensure even the finest parts are lubricated. Check the rubber supports: After lubricating the lifting mechanism, inspect the rubber parts supporting both ends of the glass. If the sliding condition of the glass is poor, apply a rubber protector.
