Looking for some information on this issue of my doors locking and unlocking on their own. It happens when the vehicle is off and in park. I have replaced the actuator as of about a year ago. This problem just started in the past few weeks. Recently locked my wife out of the vehicle while it was running.

It does have a aftermarket starter placed in it. I’ve done some searching but can’t seem to find much. Thank you for any help.
 
I know it sounds weird, but search for threads about a connector in the tailgate. Mine was doing this, I cleaned the connector and it stopped. Did this more than a year ago and it hasn't come back. FYI - terminals were clean with no corrosion.
 
Which connector?
It's in the wiring to the tailgate locking mechanism. I think it is close to the middle, underneath the carpet cover thing. Let me know if that doesn't make sense.
