Hey guys just wondering if you can help me with my rear power window. It will go down about half way then i have to force it down while pressing the button.....same thing on the way up, it will get to these certain points then i would have to force it up.

I have remove the door trim and seems like the motor and runners are ok from external view. At one stage i thought it might be something simple like lack of lubrication but i tried greaseing it up and it didnt help. I was thinking about taking the regulator out but dont know how i should go about doing it.

Hope these pics might help you see where i'm at:
