Hi, recently my front driver side door lock no longer locks or unlocks electronically. If I press the button on the dash or remote, I hear a feint grind or moaning noise. As I was looking online it appears to be my door actuator. Does this sound correct? If so, how hard would it be to replace? I was looking at parts and found part #[FONT="]931-314[/FONT] at autozone. Is that the only thing I would need? The door still functions with the key and pulling the handle, just not electronically. I have a 2013 Chevy Cruze 1LT RS.
