Did you grease the track at the bottom of the window that the plastic guide runs in? Did you perhaps replace that?

I just finished replacing one of the plastic pieces that broke. I used a clevis pin in place of the supplied rivet. I did had to turn the pin in my lathe but you can enlarge the hole in the regulator arm instead.
