I have the same problem with my doors, but it's on all four! I brought it to the dealership and they want $1800 to fix it, said it was the actuators??? I brought it to another shop and they said $1600 to fix it. Apparently the actuators cost $1000 and labor was $600. That's a bit rediculous if you ask me.
As far as the window, I had that problem on all four windows and when I brought it in to have the doors looked at, I picked up the car and they mysteriously work now! :) Maybe something was loose, I don't have a clue.
