Reviving this thread for some help. A few months ago I first noticed my doors would occasionally randomly start locking while driving. That stopped and a few months later started having an issue where the doors would not unlock with the remote and now the interior lock buttons don't work either. What is odd is this is completely intermittent. Everything will work one day and then, everything will not work the next day. This is a regular cab, that I added the electronic tailgate lock to, when it is not working, this includes both doors AND the tailgate. Remote will get the lights to flash as normal but absolutely nothing unlocking and no mechanical noise of anything trying to move. Give how it is either all working or all not working, I don't believe it is anything inside the doors but something ahead of that. Any thoughts on where I should start?
