I changed mine this past Saturday. I paid $280.00 and it took 2.5 hours to change. The screen is held in by 8 screws. One of the screw mounts was broken. This is what caused the issue. You Tube has some very good videos on how to do it.I had the exact same problem. It gradually quit working until it wouldn’t work at all. I have less then 60,000 miles and of course was told that it would cost 1500 with installation and on top of that there are no new ones so I had to get a refurbished one. WHAT....,,,,paying this price to basically get one just like the one they took out. Come on we all know this one won’t last long. I talked to the parts manager and he told me there is no new ones available. He told me they get 3-4 in a week that have to be replaced. Are you kidding me? Just another racket at to how Cadillac gets more money from the consumer. Based on 1000 dealerships across the county think about their additionally income to there bottom line. $400,000 a month. If Cadillac was the reputable dealer they should of been they would of done a recall. When mine gets fixed it’s gone. Will never own a Cadillac again and I suggest you not either.
