Over the last couple weeks my backup camera is just showing a grey screen but still has a bit of the picture (see attached), not a clear colour one as it should be.
I ruled out the actual camera in the tailgate because when I used to take off my tailgate the screen would just go blue, now it stays grey when unplugged, so I'm thinking it must be the video in the mirror that has gone bad.
I'm just out of warranty (41,000 miles), so taking it to the dealer is not my first option. Has anybody experienced this before? I've searched for a wiring diagram, but I doubt this is an issue as it's all factory, and the video has momentarily come back for a few minutes, and then back to grey.
Any ideas? Thanks in advance!
