I recently replaced the central vacuum pump (with used one-210 800 0648) which controls the rear headrest, trunk lock and door locks. Everthing worked fine for a while. Now the rear driver's side door and the trunk won't lock when I turn the key. they will unlock however. The other doors lock fine. Any ideas? Does the same line control both these locks? Does anyone know exactly what is controled by the various vacuum lines from the pump? Thanks

This sounds like the same problem I'm currently experiencing, and in my case it's due to a faulty actuator inside the door. When I try to lock/unlock, I can hear the hissing of an air leak in the door. Part is about $30.
