Circuit breakers in cars automatically reset themselves, so the owner would
have no need to find them - therefore their location is not always given in
manuals, the way fuses are. Most likely, the power source to the breaker
has burned out or become disconnected. If you have the service manual for
the car, it should include a wiring diagram. That will show where the power
door lock circuit gets its power. Go there and make sure all is OK. Find
the wire (the manual will tell you the size and color) and follow it to the
breakers (they are probably in the left kick panel). Inspect the breakers
and all the connections involved with a test light (available at your local
auto parts store for a few bucks) and you will find what is not making
contact.

> Well, I did check the fuses. But according to the owners manual the power
door locks are protected by a circuit breaker. There is no fuse on the fuse
block for it. All fuses for the other systems are fine. Apparently, the
writers of the manual assumed that no one would ever trip those circuit
breakers, and therefore didn't need to know where they are. How thoughtful
of them.
