Why did three of my window controls stop functioning? Gmc sierra 2007
3 or my 4 car windows don't currently work for unknown
reasons. The front passenger side door is currently the
only one that works. All the others fail to roll down and up
when using the door controls. The left passenger window
will also not work on the drivers window controls and only
works for the password window controls. The other
controls don't work. I am unsure why but earlier a few
months ago the driver side controls for the front
passenger window slowly stopped working. Then
yesterday they all stop working suddenly except for the
front passenger control on the passenger side. Not sure
why
