I'm at dealer visit #6 to fix my power lock issue. They tested all wires as communicating fine. Changed the latch mechanism, the actuator and a control module so far. Anybody have any ideas? Truck is a 2017 with about 45000 miles on it. Been an ongoing problem for the last 2.5 years. I take it in when I have time or have something else that needs repairing, but I've had no luck on this issue. it's only the drivers door that doesn't work properly. Will lock eventually, but sometimes takes a half dozen or more tries with either the lock button or the remote. Once it locks properly it works perfectly until the truck is started. Once it's started it resets back to the improperly functioning state. The lock cycles through locked/unlocked multiple times when the button pressed just like when you try to lock it with keys in the truck. Keyless entry/go truck. Unlock always works, but not keyless if I had to press the lock more than a couple times to get it locked. Still under warranty. I did notice on this last attempt I lost the auto up/down feature on the drivers power window. Still works normally on passenger side.
