When I get in my 2011 Dodge Ram 1500 and close the door, the flashers blink twice. This just started this week. No key in the ignition, blinkers not on, etc,.
Just a guess but that sounds like your alarm system arming or disarming.
I thought about that but it happens first thing in the morning when i get in my truck in the garage so the alarm isn't on.
