Door locks keep clicking dome lights activating

[dentom052]

Above about 20 mph, my door locks and dome lights keep activiating every couple seconds. Message says "door ajar". I can get it to stop most times by stopping and reshutting all doors. But the doors seem to be latched fine.

I can also get it to stop by using the drivers door lock and unlock button.

I'm a master light and heavy truck mechanic but don't have the software to look up body codes to troubleshoot. I assume a door shut switch is going bad!
