Door will not lock or open

Passenger side door will not lock or open, while all other doors work by remote.

I have to come around open door press the knob in and then lock other doors with remote.

It will not lock or open by remote either, I have to get into the car and then pull door handle to open, driving off will lock other three doors, this one is not working nothing happens.

In short it is not working.

Window on the door works fine.

I do not have a problem of the locks hesitating up or down, it is a definite up or down, when you hit the lock switch, which I rarely do, as the doors are auto lock on ten mph, they lock themselves.

No tick or sound from that door lock, just silent, if it is trying, then I have not heard it, but I am sure no sound.
