Window motor?

[white4d96]

My driver's side window keeps having these fits where the window won't go up or down. If I push down on the glass, it moves down a bit, feels like it tightens up, then I can operate it normally. Dead spot in the motor?

Does the track need to be greased?

I don't know, but I don't think that would make the whole window loose. If I put my window halfway down I can grab it and pull it like an inch up or down.
