Electrical problem
2008 Pontiac G6 6 cyl Front Wheel Drive Automatic 67668 miles

Hi, I own a pontiac g6 2008. All my power windows work except for one. The thing is i can hear the motor going up and down, but the window does not budge. i would have to manually pull it down. But wen the window is all the way down i use the switch to put the window back up it works. Is the window not attach to something?? and is it possible for me to fix it myself?
