I just got a 2017 Prime advanced from carvana. I'm still figuring it out. Tonight there was a bright blue light flashing from the top of the dash near the driver's side door. It stops when the car is unlocked and the door opened. It starts again when the door is closed and the car is locked. I can't find anything about it in the manual. Any clues? Guesses? Sorry, I'm new to this. If someone can tell me how to do it I will post a short video of the flashing blue light.
Probably the charging indicator. There are 3. As the traction battery charges additional lights blink. When fully charged they all turn off. Did you mean the passenger side?
1st guess: it's an aftermarket alarm system. There won't be anything about this in the manual- it would have had its own manual that somehow was not included in the transfer.
