I have a 2015 Traverse. Recently the passenger door auto lock will only work when the door is open. When all the doors are closed the lock switches and fob will lock or unlock all the doors except the passenger door. If the door is open then it locks and unlocks with no apparent issue. I have replaced the actuator and the inside door locking button. I am out of ideas. Has anybody experienced this issue and if so what ended up being the solution?
