ok boss if the window rolls down a little then stops try this. pull the inside door cover off and look at the motor and try and move the window up and down, some times a bolt will break and cause the motor to move causeing the gears to bind. if it dosent work at all check the fuse, if its not blown use a multireader on the up down button to see if your gettn power there, if your not then its most likely a faulty line, but if you do get power at the button in and not out then its probley button, and if your gettn juice from both in and out then its probley the motor or a faulty line from the button to the motor. hope this helps
