ACCEPTED

You need to pull the door panel to diagnose the actuator.One question can you hear anything happen in the front doors when you hit the lock button?If you can the acuators are weak and need replaced.If you can't you need to check for power and ground at the actuator with a test light.Place one end of the test light on each terminal in the connector of the actuator after you unplug it.Operate the switch if it lights replace the actuator if it doesn't you have a bad wire.We will get into how to check that if need be.

Yes unless you can see of feel some mechanical binding in the latch.There is one other possibility the power or ground to the actuator could be weak.To check that you need to make a test light from an old sealed beam headlight.Then operate the switch both ways.If it can operate the headlight and make it shine bright the electrical is good.That can be a handy tool for any electric motor test or light test. on a vehicle.Saves time and misdiagnosis.
