But really if the only problem you are having is with the power door locks then the solution is rather simple.

Just disconnect the vacuum module/servo in each door from the vacuum supply, plug the lines, and hey presto! You now have manual locks.

Plug only the lines going to the servo in the doors and leave the servo lines open. This way the air can enter and leave each side with ease. You could also disconnect the rods leading from the servos in the door to the lock assembly and the door locks would move even faster and easier.
