Mine is a 2019 Dodge Grand Caravan,I was driving this morning and all my idiot lights came on and the radio ,turn signals went off. The display showed no bu5(of course it meant no bus). I drove home and shut it down after 3 hours I cranked it back up ,same thing ,turned it off cranked up again everything is back to normal.This happened in January also, I unhooked the battery for 20 minutes and everything was ok. The dealer said it is the can bus ,I want to know how hard is it to fix that can bus? Photo enclosed ,also the wiper blades wont turn off either.

how do I attach a picture,manage attachments isn't

The wipers are going also.
working for me.
