Sounds like you need a new master switch assembly (the drivers side switches). IIRC if they start to act up it will affect the use of the other independent switches. When you go to remove the switch panel from the door it would be best if you removed the entire drivers door panel to release it as the top edge of the switch bezel loves to break when you even look at it. Getting it out via removing the door panel seems to be the best way to avoid a broken bezel. Just pop the metal spring clip loose from the bottom and out it comes.
