This morning I tried to unlock the doors with the remote. The locks just went up and down. I could unlock the hatch with the key. I could unlock the passenger door with the key if when I turned the key I hurried up and pushed in the door knob. Once in the car (from the passenger door) I tried to unlock from the driver's door control. The locks did the same thing, up and down quickly. It was cold this morning with some snow. I have never had this problem before in the same kind of weather.
Seems the door lock power switch is failing, due to overtravel of the contact lever. A stopper inside is worn but there is no replacement part for this. You either replace the door lock actuator assy or modify the stopper.
