I have a 2020 Horizon 42Q. The turn signal and rear view cameras work great when it is cool outside. With summer temps greater than 90F, the cameras begin to grey out and I lose the video signal. The turn signal cameras access fine when I turn the signal on and the rear view camera accesses fine when I place the transmission in reverse. Depending on how high the outside temp is, I may have full video, partial gray video or no video at all. Thanks for your help.
