2001 Power Door Lock Quit

I was driving my son's Blazer and noticed his power door lock does not work. Nothing else seems amiss. There is a click when the button is togggled. Fuses ? Any help would be greatly appreciated. Thanks.

The click you hear is the relay that operates the lock actuator, which means the switch is able to power the relay. Could be a broken wire between the relay and the lock actuator in the door, or a faulty lock actuator. Common place for broken wires is in the rubber boot between the door jamb and the door on the driver side.
