The door lock is not a vacuum problem.
The vacuum pods in the front doors are partly electrical and the electrical has to take care of the sucking and blowing of the central locking vacuum pump.
If the passenger door reacts fine when opening and closing the car from the drivers side and the trunk, there is nothing wrong with the vacuum system.
The electrical part of the passenger doors locking system is out of order (it is possible that it is just the connector on the pod that went loose)...
An electrical adjusted seat that moves to fast or slow is something that might be adjusted underneath the seat. I don't know whether it is possible to adjust the speed of the adjusting-motors...
