Doors Unlocking 2015 Silverado High Country

[DuckManiac]

The doors will unlock while driving and/or I can't use the key fob to lock doors when parked, I must use on door lock switch. This is intermittently. It may not do it for many weeks and then twice in a week and again not for some time.

It doesn't have passive door locks, only remote door lock/unloc/start.

I have changed the fob batteries and cleaned connections. No other problems.

I'm thinking a bad accuator or control module. How can a check?

Thank you for your attention.
