My electric rear window on my '90 K5 has stopped working with the window rolled down about an inch (nice in the rain... at least it's not all the way down, right?). The electric motor is still working, so it's something to do with the regulator. I've been told either the regulator has gone bad, or it just needs adjustment to make the window work again. Unfortunately, the Haynes guide I checked out from my library had zero information on the electric rear window. Does anyone know of any good articles or manuals that'll help me tackle this myself? Or just know how to briefly explain the easiest fix? I'm semi mechanically-inclined, just haven't had much experience in the window department! Thanks for any advice!
