You'll need to track down the electrical problem. Most likely it's related to the door lock circuit, meaning that it's probably not a single door lock actuator, but it could be. If one actuator is shorted, it could blow the fuse to the others. You'll need to track back to see where you loose power to the actuators. That may mean getting a book or visiting your dealer and begging for a copy of a few pages from theirs.

Yea, some dealers will actually help you if you're nice and act like you could actually do it yourself.
