I have a 2016 Buick Lacrosse. About 6 months ago (in the heat of the Texas summer with 100 degree temps the norm) I started getting a message that my rear view camera system needed servicing. It was a message that appeared on my console screen. Eventually, the screen quit working. Now, with the cooler temps, the screen has begun working imtermittently, and will quit once the car warms up. The screen is now most likely to work when the car has been sitting longer in colder temps. So, I'm thinking it has to be some sort of relay or fuse, that is, hopefully easy to find and replace. What say you?
