I searched for Vader's pdf file (I'm trying to replace the brushes in my window motor--never done this before), but his link was dead.

Please post if you have it. Also, can someone describe in detail how to properly pop the cap off that holds the brushes and reassemble it (with pictures if possible...I don't even know what a brush looks like aside from a few pictures). What GM cars use similar window motors if I go to a junkyard?

I usually stick to basic mechanical issues, but this is the first time I've ever taken a door panel off (it was really easy--can't believe I never did it before), and my center console trim (tried to replace a window switch).
