Same car, same problem. It's a broken wire, yep both sides. You will have to take off the piller trim between the frt & bk doors, find the wiring harness, open it and look for a broken wire. While your at it you should also remove the door panel and check there as well, take it easy as the panel is held in with plastic clips. Also make sure to remove all the screws from panel (arm rest etc.). Worse case, you might need a new window lift motor (junk yard), but you wont know that until you look inside the doors. Good Luck!
