I had a similar problem some time back on my high-mileage car. In my 
case the root cause was that the door lock switch on the one side was 
too sloppy to make a reliable connection when the switch is thrown. 
The door lock switches a really quite cheezy and consist of a metal 
wiper that rotates on a riveted pivot across a baseplate that has 
three bumps on it. The wiper is wide enough to touch two of the three 
bumps and the center bump is the ground circuit. The problkem I had 
was that over time the wiper had lost some of its tension and was not 
pressing securely against the bumps. Also the whole wiper had a lot 
of slop in it.

You can veryify whether your door switches are bad without 
dismantling your door by checking your wiring diagram and measuring 
at the door lock module by unplugging it and measuring from the 
connector contacts.
