Vehicle Application: 2000 Mazda MPV 2.5L
Customer Concern: Driver's power door lock is inoperative. The other power door locks operate and can unlock this one with a key, but the power door lock actuator isn't doing anything.
Tests/Procedures: 1. Check for power and ground across the Red and Blue wires at the actuator and if it has power when operating the switch, the actuator is bad. If there is no power, check for broken wires in the door jamb harness.
Potential Causes: Door Lock Actuator
Tech Tips: All of the actuators are controlled, but the same circuits. Since the other doors are operating, it will not be a controller problem.
