A slower up or down window action, no movement at all or a grinding noise when the window switch button is pressed will indicate there is problem with the car window regulator.
If the vehicle window regulator is electric, the problem could be caused by the following:
- The mechanism (you hear the sound of the motor, but it does not move the window. Also if the regulator has failed the glass may drop into the door panel)
- The electric motor (there is no sound at all when you press the window switch. This could mean the motor has seized or has worn over time)
- Electrical fuse or wiring (Nothing happens when you press the window switch button but the glass is still in position)
To replace a damaged or a failed window regulator you will need to remove the inner door card panel to gain access to the internal components of the door. All vehicles are different and we have made a number of videos to help assist and show the removal process of the regulators we supply:
