Need help!! Power door locks cycle by themselves

[Bushwookie1]

Ok..here goes.. took 2 1999 yukons and totally swapped EVERYTHING from one frame to the other. Everything works .well maybe to well..door locks cycle themselves every 20 to 30 minutes. Even when no key in ignition. I opted to install a duel battery. Anyone have any idea why this is happening?? Could the dead key fob by my culprit?? Thanks for ANY answers guys. Still scratching my head

Welcome to your first post on the forum.

Whenever strange electrical problems pop up, lots of threads here recommend checking all grounds.

Personally I'd unplug all of the door lock switches and see if that eliminates the problem. Then connect them one at a time to see if you can locate the culprit.
