I pulled the pass side door panel off to have a looksee at the window regulator. That widow would go up a little and struggle the rest of the way. WELL... DO NOT use whatever that stuff is that WD40 calls silicone. After cleaning all the sticky gooey crap out and using CRC (real) silicone, I re-greased the slide for good measure and voila, nice even speed. Tomorrow is drivers side.
