Ok I findally got around to inspecting whats happening with my window not rolling up all the way, I see the moon shaped gear has 4 teeth broken apart, Thats why the window doesnt roll all the way up to the rubber seal. I am wondering if anyone has done this job, Ive never did this before, I am pretty confident I am of handling this task. And would any one have a part # and also wheres a good place to order it GM Dealer?.

thanks in advanced.

get the parts at a junk yard. Should be plenty. If you REALL wanna order parts, go to GMPARTSDIRECT.COM

They're cheaper than dealer prices.\

Although u should be able to call any chevy dealership (I'd visit them) to get the parts numbers and pictures
so u at least know what to look for.

Hope that hel[s.
