Blinking lights 2005 Dodge minivan



My 2005 Dodge minivan lights (interior, dash and all exterior) flash (blink) on random occasions. I cannot establish a cause or a cure. Sometimes they blink really fast, sometimes a more subtle speed. Dealer has checked out charging system and battery - but since it is a random problem, I can’t exhibit it when I have the car in. Anyone with a similar problem - and hopefully a cure?


Did they check the leads into the power distribution center under the hood?
