shaanxi, this is strictly for the "what its worth dept."

When doing my 52 windows I had some of the same problems. The driver side was really hard to roll up. So much so that I broke it. Standing back looking at the door outline I could see that the door, or window, is not really square. The latch side of the door has a "slant" to it as the window rolled up.
I took both the side windows back to the shop that cut them with the SAME pattern I had given them. Turns out the glass cutters had let the glass pattern slip a little making the glass out of proportion. They cut me two new glasses without charge and wow, what a difference. The driver side is a breeze and the passenger side is OK.
Maybe over the years someone cut new glass to old worn out window channel and now with new stuff its tighten up?

...........just a thought.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
