Hi, im new here, and i am having some problems with my rear window driver side rolling up. I have purchased a new motor and regulator and that is not the problem. i have also tried a new switch and that is not the problem. i think it has to do with some type of cable or something. any one know what it might be?

 

See if the motor will spin (both directions) when not attached to the regulator. I think there is a power window control box under the dash.
