Using the key remote the drivers door wont lock. All the others lock, but the drivers door remains unlocked and there is no beep or flashing lights. I doublechecked that all the doors are closed all the way, what could be the problem here? Is there something I'm doing wrong? I sure hope the door lock actuator didn't break already, it was working fine a few days ago. the car only has 71k miles on it.

 

it's a good possibility that the motor went bad.
