Why is my 2015 chevy equinox backup camera not working?

There are a number of reasons that Your 2015 Chevrolet Equinox's backup camera could be malfunctioning, so I'll try to help You narrow it down. The most common reasons seem obvious, but are worth giving a second look to regardless. You'll want to make sure that Your lens is in good condition, free of obstruction, and in working order. If the lens is clear, but You still can't see anything, Your most likely culprit is the wiring. It can be difficult to diagnose a backup camera's wiring, since there's so much of it (traveling the length of the vehicle). You'll want to first check where the wiring couples with the camera, and next where it couples with the display. If these both seem pristine, You'll want to trace as much of the visible wire as You can, ensuring that You can't see any burns, breaks, or crimps. Let us know how that goes, and if You'll need further guidance.
