Passenger window issues

[gixxerss]

i have a strange window issue I’m hoping someone can shed some light on. Passenger window stops when going up and goes back down. If I inch the window up little by little it goes all the way up. It’s almost like it’s catching on something but the motor works fine and doesn’t go up slow. Removed the door panel and all seems as it should.
Any insight is appreciated.

Try greasing the railings in the door and the rubber surrounding the glass with some silicon grease.
