It first started out that the drivers door would not lock after putting truck in gear, then gradualy got to the point where you had to push the door button 2 or 3 times to get the door to lock, it did try moving a little bit each time but now it won`t work at all, I have to push the button down by hand and use the key to unlock door and there seems to be no problem with passenger side door lock. driver side lock switch still works on passenger door. Passenger side door lock switch works but only on that door.
