Rearview and Side view cameras.

[Cubanredneck]

Ok so i was driving down the highway and display for my cameras were working normal. At sunset turned on my lights and the display went crazy. When the lights are off the display shows the rear and respective sides with a turn signal. When i turn the coaches lights on the display gets stuck on the drivers side camera and wont change. If i turn on my emergency flashers the display jumps from driver side to passenger side camera non stop. What could possibly be causing this madness. Im about to take the whole thing apart on the dash but some insight before hand would be great. Has any one experienced this behavior before?
