I have had two repairs done for collision on my 14 cadenza, right rear quarter panel and front left. My radio quit working, nothing shows on display... Then magically, it's on, everything works perfectly, it did take a while for the display to come up to fill color. Then a few days later, it doesn't work again.. It has gone back and forth for our five times. It's been months now without working.. Other clues, my dime lights will light up if the depth is manually activated, they will not light up upon the doors being opened... The entrance lights and front floor lights work. I am thinking it is a faulty module not a fuse... Any ideas would be appreciated.
