Problem :
locks cycle randomly and getting worse either unlock (in park) locked (driving)
parking lights turn on & off with locks
What I’ve tried :
main battery connections. Remote FOB. Main grounds. Mega fuse. Pulled BCM apart to look for obvious burns.
Symptoms will duplicate with key turned once. I’m suspecting the ignition switch or remote receiver??

Door lock switch in the driver's door would be my first thing to check. It is the master control for all the locks. Especially if you got the truck used and previous owners left a window open in the rain, so switch got drowned.
