So my drivers side power window will only go down about a quarter of the way, but I hear the motor continue to try to take it down. And when I roll it up it makes a grinding sound when the window reaches the top. Anyone know if this is the motor or something else? I originally thought the motor, but the fact that it stops at a specific point and once to keep going up makes me wonder. Thanks in advance!

 

sounds to me that you have a bad window regulater. only one way to find out and that is to take the door panel off and check out to see what everything is doing

 

My passenger side window is doing the same exact thing. I have my door panel off, I can see the motor and the track, but that's about it. What am I looking for?

 

have someone move that window up and down. Look to see if you can see where it is binding or making noise. make sure your regulator moves freely
