Pardon me for being dense, but "where" is the thread which explains the update? I have a 2016 Journey which I purchased with a rebuilt title, so I don't get any assistance from Dodge dealer. Has been a wonderful vehicle with exception of map issue.
If you guys have not resolved the door lock problem, I am going to assume it is a wiring issue. I had the same issue on an older car of mine, and it was the wire from the relay to the actuator. The wire had gotten old and although it was getting a current when I pushed the button (and worked intermittently), it was not enough power to give it a full current. Just a thought.
