Car Window Fails

Car Window Fails


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:

  • Switch
  • Motor
  • Wiring
  • Window regulator (which transfers power from the window motor to the window glass).

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.
