Hello, I have a 2008 CTS without navigation. From time to time my radio and ac controls will randomly go black and stop working. Sometimes they will come right back on and other times they will stay off for a day or so then randomly come back on. It started with just the radio but now its the entire panel but the clock, traction control and hazards still work. Now they have all been off for more than a week. I cannot get it to record CDs either, when I push record it looks like its working but then says something about not being able access the HDD while initializing. It also seems like it is losing power or the memory isn't working when the car is off because sometimes when I start it the CD will start at the beginning and not where it left off. I love the car but these Radio/AC Control issues are driving me crazy. Any info will help.

Thanks

 

I have the exact same problem as this. I was just going to acquired a new panel from a parts car and see if that fix my problem.

 

My radio eventually went out and never came back on and had to replace it.

 

so i followed your lead and source a known working radio and control panel. Put in my car and they don't work. Do I have to take the car back to Cadillac dealer to have re-programmed or coded.

 

I was able to fix my problem by replacing the radio harness plug. I guess mine had a short circuit. I found another car and cut the harness plug and then splice it to my harness. Plug everything back up and bingo, everything working.

 

Lol sounds like mine but mine is so far the heater n AC just comes of some days it on off on off the whole time your driving. I'm thinking about trying a used one but not sure yet hope you get a answer on this one. Yea it drives you nuts
