The driver door was unlocking and locking and now it will not open at all

Hi,

Do you mean the door will no longer open or the lock actuator no longer works? If I'm understanding correctly, the issue is the lock assembly itself.

If that is correct, I attached directions below for testing. Take a look through them and let me know if you are comfortable doing them.

Also, let me know if other doors have been affected as well.

Take care and let me know what you find or if you have other questions.
