why won't my power window on my 2002 silverado close the last inch or so?

i bet you have to check the window mechanisim there is a plastic track with teeth on them i bet it slipped a couple of teeth and thats why its not going up all the way take door panel off you will see the plastic track in there where a gear on window frame that rolls up n down on that track i bet its off a couple of teeth easy fix if you know what you are doing

Thank you very much for the help. I will check and hopefully it's just that.
