Most likely a fault with the master switch.
This is rather complicated to explain so I don't know if I can get the message through.
When the master switch for the respective door is not providing continuity in the rest position, the rear switches would not work. Likewise it can also be the reverse condition.
When using the master switch to control, you are able to get the windows moving because the switch is being turned to open and close some connections therefore you have no problem.
