Got 2 birds with one stone today. Discovered loose nut while replacing passenger mirror today. I noticed a 4th nut next to the 3 mirror mounting nuts backed way out. I saw the stud came through a slot as for adjustment. Lightly tightened nut. Then rolled window up and down a few times. All seemed good, so torque it. The original bad sound was as if the window mechanism had movement.
