Sorry I'll elaborate. The rear camera has not been working for 4 months. Last week before a road trip and after a oil change I cleaned the engine. After that the camera worked and the button did not. After the road trip and lots of KM on gravel roads I rinsed the engine off on the low wash setting and the button worked and the camera didn't. The wiring harness on the hatch is not in great shape and I have fixed several cracked wires in it. I just can't figure out how the two switched (button/camera) and the only link is the wash on the engine. How are the two connected and why or what would be a reason why only one can work at a time.
