Make sure that the glass is the proper thickness. I ran into the same problem scratching my head because I replaced the channels and riser. It still bound up in a couple spots. I tried silicone grease on the riser etc. It wasn't until I removed the passenger side to replace the channels I noticed the passenger side glass seemed to be thinner. It was. Someone replaced the drivers side with a 1/16" thicker glass.

Now the right thing to do is to get the correct glass but I can't seem to find anyone that has that one piece. I took a small strip of 1/4" plywood and gently tapped it into both channels to widen them a bit. Worked perfect. Now if I ever break that glass I will be wondering why the new glass is so loose because of course I am going to forget.
