When a car window fails to open or close, it can be more than an annoyance. A non-functioning power window compromises personal security. It may also allow precipitation to get inside the passenger compartment.
When all the windows are in shut-down mode, a faulty fuse may be the culprit. Otherwise, if the problem window does not produce the sound of a motor behind the door panel, the trouble may rest with a faulty:
If the plastic guides in the regulator break, the metal cable will come loose and allow the window to fall inside the door, requiring the regulator assembly to be replaced.
TIP: Replacing a window regulator is complicated by the fact that the inside of the car door must be dismantled in order to gain access to the part.
