No, every lock has it's own vacuum line which work independently, all via the vacuum pump.
I had an air leak in my driver's side rear door and I could hear air hissing. It turned out to be the black rubbery thing (I think the actuator?). Yes, definitly listen for a hissing sound when it's struggling. But you have thick door panels and might not hear it as easy... more than likely you're going to need to take the door panel off anyway though... it's not that difficult. Keep us posted.
