Phantom Locking/Unlocking

See video attached. Doors unlock themselves constantly when opening/closing or when hitting bumps. Any insight? Might just remove the fuse if there is one.

 

Could be a bad ground or possible short in the wiring bundle where it passes through the door jambs. Check the driver door first as it gets the most use and also has the "master panel" for all four door locks. My 99 Avalon has window issues, they roll down but not back up and it's due to a problem in the pass-through wiring of the driver door which of course has the panel to operate all four side windows.

 

I think the locks are negative trigger so if a wire is grounding out it would maybe do that.

 

Each door latch has a little switch in it that tells the position of the latch (open or closed). Sometimes the switch will get stuck halfway between the two positions, even tho the door latch is still latching and working.. since the switch is hovering between open and closed it will jump back and forth and make the locks cycle. Try spraying silicone lube or penetrating oil directly into the latch and work it back and forth by opening and closing the door.. work the lube back in there where it can hopefully free up the switch. This switch is inside the latch, not the door ajar switch on the door jamb..

Also open the door panels up and look for chafed or exposed wiring. Check the loom where it goes from the door and jumps across to the a-pillar. The constant flexing can damage wiring in that area..
