These are off the window regulator.As you look at your window regulator - the clip is located on the part that slides up and down the rail. It is used to hold the tension of the cable ends together and allows your window to go up and down. You may have to bend the ends of the clip to make sure that it fits back snug. Now expect to have to play with this as you try to get the two ends of the cable into the clip and then the clip with the tensioned cable back into the slide. The best way to analigize it is to picture the end of a bicycle brake cable being pressed fit into the brake lever on the handle bar.
I believe the little white item goes inside the white square plastic part on the rail. The back clips into place and can be opened to reinstall.
On a different note - this deals with windows that go partially up and stops. You may notice many threads with people having window symptoms of only going part of the way up - but the motor seems fine and the switch is ok.
As you have the regu;ator off the car take a look at the aluminum part that is attached to the regulator jaw by way of a rivet.
I had the same problem. So while I had ithe window regulator out I reconected the power and observed the action of the window regulator jaw going up and down and sure enough it went 1/2 ro 2/3 way up and stopped. Motor was fine.
I observed that the larger aluminum piece connected by the rivet is supposed to hook onto the piece that rides up and down the track. I discovered that the aluminum was slightly bent (hardly noticeable) and allowed it to swing off the other piece and out of position. Nothing actually broken but while the regulator went to the top the alignment was thrown off and the window would not make it to the top.
I simply put it into position and slighlt bent the ends of this aluminum to make sure that it remained in place and no more problems for the past year.
Wish I could figure out how to attach pictures I took.
Good luck.
