Drivers side rear door lock does not react to the fob. Have to lock & unlock door manually. Shows no codes. Any suggestions?

don't know, but could it be the child safety switch on the door

 

Mine does that from time to time. Someone else had that problem awhile back. It's something binding in the linkage. Mine only does it when it gets real cold.

 

mine did the same. i bought a new actuator but that did nothing.. then i took apart the plug that comes out of the b pillar. its where all the wires for the back door come from. thats when i discovered that a wire was broken. i spliced the wires and viola it fixed the problem. the wire broke from opening and closing the door the wires are of poor quality
