I'm having an issue with my power door locks. When I press down on the buttons to lock and unlock the doors, I hear the relay and the passenger lock actuator working, but no sound from the driver lock actuator and both locks aren't unlocking. I can unlock the doors with a key and pulling on the door handles from inside. I don't have a button box on my key ring to test that method. I can fix this issue, but I just need to know what it is or where to start. I bought the truck like this. Can someone please help me figure this out so I can fix it instead of my family looking at me funny because of this issue?

 

Over time the door lock actuators get weak. When this happens they don't push hard enough or far enough to fully unlock. To fix them, replace the door lock actuators.

 

Thank you. I will get these parts.��
