Why is my 2012 Kia Sedona backup camera not working?

If the back-up camera in Your 2012 Kia Sedona is not working, then the first thing to check is a blown fuse. If the fuse is intact and the issue still persists then You should try cleaning the lens and checking the wires for any fault. The camera failure is due to loose or faulty wires in most cases. Another reason for the camera to stop working is damage to the lens. In this case, You will have to replace the camera and install a new one. The cost of the camera depends on the quality You select for the replacement. You can find universal aftermarket cameras for half the price that You will pay for the more recommended OEM ones.
